chapter is only apparent. It is quite clear, from the nature of the
reasoning which is here used to prove that it is more improving to
work with others than to work alone, that the studies of pupils only
are under consideration here.]
496.
OF STUDYING, IN THE DARK, WHEN YOU WAKE, OR IN BED BEFORE YOU GO TO
SLEEP.
I myself have proved it to be of no small use, when in bed in the
dark, to recall in fancy the external details of forms previously
studied, or other noteworthy things conceived by subtle speculation;
and this is certainly an admirable exercise, and useful for
impressing things on the memory.
497.
OF THE TIME FOR STUDYING SELECTION OF SUBJECTS.
Winter evenings ought to be employed by young students in looking
over the things prepared during the summer; that is, all the
drawings from the nude done in the summer should be brought together
and a choice made of the best [studies of] limbs and bodies among
them, to apply in practice and commit to memory.
OF POSITIONS.
After this in the following summer you should select some one who is
well grown and who has not been brought up in doublets, and so may
not be of stiff carriage, and make him go through a number of agile
and graceful actions; and if his muscles do not show plainly within
the outlines of his limbs that does not matter at all. It is enough
that you can see good attitudes and you can correct [the drawing of]
the limbs by those you studied in the winter.
[Footnote: An injunction to study in the evening occurs also in No.
524.]
On the productive power of minor artists (498-501).
498.
He is a poor disciple who does not excel his master.
499.
Nor is the painter praiseworthy who does but one thing well, as the
nude figure, heads, draperies, animals, landscapes or other such
details, irrespective of other work; for there can be no mind so
inept, that after devoting itself to one single thing and doing it
constantly, it should fail to do it well.
[Footnote: In MANZI'S edition (p. 502) the painter G. G. Bossi
indignantly remarks on this passage. "_Parla il Vince in questo
luogo come se tutti gli artisti avessero quella sublimita d'ingegno
capace di abbracciare tutte le cose, di cui era egli dotato"_ And he
then mentions the case of CLAUDE LORRAIN. But he overlooks the fact
that in Leonardo's time landscape painting made no pretensions to
independence but was reckoned among the details (_particulari_,
lines 3, 4).]
500.
THAT A PAINTER IS NOT ADMIRABLE UNLESS HE IS UNIVERSAL.
Some may distinctly assert that those persons are under a delusion
who call that painter a good master who can do nothing well but a
head or a figure. Certainly this is no great achievement; after
studying one single thing for a life-time who would not have
attained some perfection in it? But, since we know that painting
embraces and includes in itself every object produced by nature or
resulting from the fortuitous actions of men, in short, all that the
eye can see, he seems to me but a poor master who can only do a
figure well. For do you not perceive how many and various actions
are performed by men only; how many different animals there are, as
well as trees, plants, flowers, with many mountainous regions and
plains, springs and rivers, cities with public and private
buildings, machines, too, fit for the purposes of men, divers
costumes, decorations and arts? And all these things ought to be
regarded as of equal importance and value, by the man who can be
termed a good painter.
501.
OF THE MISERABLE PRETENCES MADE BY THOSE WHO FALSELY AND UNWORTHILY
ACQUIRE THE NAME OF PAINTERS.
Now there is a certain race of painters who, having studied but
little, must need take as their standard of beauty mere gold and
azure, and these, with supreme conceit, declare that they will not
give good work for miserable payment, and that they could do as well
as any other if they were well paid. But, ye foolish folks! cannot
such artists keep some good work, and then say: this is a costly
work and this more moderate and this is average work and show that
they can work at all prices?
A caution against one-sided study.
502.
HOW, IN IMPORTANT WORKS, A MAN SHOULD NOT TRUST ENTIRELY TO HIS
MEMORY WITHOUT CONDESCENDING TO DRAW FROM NATURE.
Any master who should venture to boast that he could remember all
the forms and effects of nature would certainly appear to me to be
graced with extreme ignorance, inasmuch as these effects are
infinite and our memory is not extensive enough to retain them.
Hence, O! painter, beware lest the lust of gain should supplant in
you the dignity of art; for the acquisition of glory is a much
greater thing than the glory of riches. Hence, for these and other
reasons which might be given, first strive in drawing to represent
your intention to the eye by expressive forms, and the idea
originally formed in your imagination; then go on taking out or
putting in, until you have satisfied yourself. Then have living men,
draped or nude, as you may have purposed in your work, and take care
that in dimensions and size, as determined by perspective, nothing
is left in the work which is not in harmony with reason and the
effects in nature. And this will be the way to win honour in your
art.
How to acquire universality (503-506).
503.
OF VARIETY IN THE FIGURES.
The painter should aim at universality, because there is a great
want of self-respect in doing one thing well and another badly, as
many do who study only the [rules of] measure and proportion in the
nude figure and do not seek after variety; for a man may be well
proportioned, or he may be fat and short, or tall and thin, or
medium. And a painter who takes no account of these varieties always
makes his figures on one pattern so that they might all be taken for
brothers; and this is a defect that demands stern reprehension.
504.
HOW SOMETHING MAY BE LEARNT EVERYWHERE.
Nature has beneficently provided that throughout the world you may
find something to imitate.
505.
OF THE MEANS OF ACQUIRING UNIVERSALITY.
It is an easy matter to men to acquire universality, for all
terrestrial animals resemble each other as to their limbs, that is
in their muscles, sinews and bones; and they do not vary excepting
in length or in thickness, as will be shown under Anatomy. But then
there are aquatic animals which are of great variety; I will not try
to convince the painter that there is any rule for them for they are
of infinite variety, and so is the insect tribe.
506.
PAINTING.
The mind of the painter must resemble a mirror, which always takes
the colour of the object it reflects and is completely occupied by
the images of as many objects as are in front of it. Therefore you
must know, Oh Painter! that you cannot be a good one if you are not
the universal master of representing by your art every kind of form
produced by nature. And this you will not know how to do if you do
not see them, and retain them in your mind. Hence as you go through
the fields, turn your attention to various objects, and, in turn
look now at this thing and now at that, collecting a store of divers
facts selected and chosen from those of less value. But do not do
like some painters who, when they are wearied with exercising their
fancy dismiss their work from their thoughts and take exercise in
walking for relaxation, but still keep fatigue in their mind which,
though they see various objects [around them], does not apprehend
them; but, even when they meet friends or relations and are saluted
by them, although they see and hear them, take no more cognisance of
them than if they had met so much empty air.
Useful games and exercises (507. 508).
507.
OF GAMES TO BE PLAYED BY THOSE WHO DRAW.
When, Oh draughtsmen, you desire to find relaxation in games you
should always practise such things as may be of use in your
profession, by giving your eye good practice in judging accurately
of the breadth and length of objects. Thus, to accustom your mind to
such things, let one of you draw a straight line at random on a
wall, and each of you, taking a blade of grass or of straw in his
hand, try to cut it to the length that the line drawn appears to him
to be, standing at a distance of 10 braccia; then each one may go up
to the line to measure the length he has judged it to be. And he who
has come nearest with his measure to the length of the pattern is
the best man, and the winner, and shall receive the prize you have
settled beforehand. Again you should take forshortened measures:
that is take a spear, or any other cane or reed, and fix on a point
at a certain distance; and let each one estimate how many times he
judges that its length will go into that distance. Again, who will
draw best a line one braccio long, which shall be tested by a
thread. And such games give occasion to good practice for the eye,
which is of the first importance in painting.
508.
A WAY OF DEVELOPING AND AROUSING THE MIND TO VARIOUS INVENTIONS.
I cannot forbear to mention among these precepts a new device for
study which, although it may seem but trivial and almost ludicrous,
is nevertheless extremely useful in arousing the mind to various
inventions. And this is, when you look at a wall spotted with
stains, or with a mixture of stones, if you have to devise some
scene, you may discover a resemblance to various landscapes,
beautified with mountains, rivers, rocks, trees, plains, wide
valleys and hills in varied arrangement; or again you may see
battles and figures in action; or strange faces and costumes, and an
endless variety of objects, which you could reduce to complete and
well drawn forms. And these appear on such walls confusedly, like
the sound of bells in whose jangle you may find any name or word you
choose to imagine.
II.
THE ARTIST'S STUDIO.--INSTRUMENTS AND HELPS FOR THE APPLICATION OF
PERSPECTIVE.--ON JUDGING OF A PICTURE.
On the size of the studio.
509.
Small rooms or dwellings discipline the mind, large ones weaken it.
On the construction of windows (510-512).
510.
The larger the wall the less the light will be.
511.
The different kinds of light afforded in cellars by various forms of
windows. The least useful and the coldest is the window at _a_. The
most useful, the lightest and warmest and most open to the sky is
the window at _b_. The window at _c_ is of medium utility.
[Footnote: From a reference to the notes on the right light for
painting it becomes evident that the observations made on
cellar-windows have a direct bearing on the construction of the
studio-window. In the diagram _b_ as well as in that under No. 510
the window-opening is reduced to a minimum, but only, it would seem,
in order to emphasize the advantage of walls constructed on the plan
there shown.]
512.
OF THE PAINTER'S WINDOW AND ITS ADVANTAGE.
The painter who works from nature should have a window, which he can
raise and lower. The reason is that sometimes you will want to
finish a thing you are drawing, close to the light.
Let _a b c d_ be the chest on which the work may be raised or
lowered, so that the work moves up and down and not the painter. And
every evening you can let down the work and shut it up above so that
in the evening it may be in the fashion of a chest which, when shut
up, may serve the purpose of a bench.
[Footnote: See Pl. XXXI, No. 2. In this plate the lines have
unfortunately lost their sharpness, for the accidental loss of the
negative has necessitated a reproduction from a positive. But having
formerly published this sketch by another process, in VON LUTZOW'S
_Zeitschrift fur bildende Kunst_ (Vol. XVII, pg. 13) I have
reproduced it here in the text. The sharpness of the outline in the
original sketch is here preserved but it gives it from the reversed
side.]
On the best light for painting (513-520).
513.
Which light is best for drawing from nature; whether high or low, or
large or small, or strong and broad, or strong and small, or broad
and weak or small and weak?
[Footnote: The question here put is unanswered in the original MS.]
514.
OF THE QUALITY OF THE LIGHT.
A broad light high up and not too strong will render the details of
objects very agreeable.
515.
THAT THE LIGHT FOR DRAWING FROM NATURE SHOULD BE HIGH UP.
The light for drawing from nature should come from the North in
order that it may not vary. And if you have it from the South, keep
the window screened with cloth, so that with the sun shining the
whole day the light may not vary. The height of the light should be
so arranged as that every object shall cast a shadow on the ground
of the same length as itself.
516.
THE KIND OF LIGHT REQUISITE FOR PAINTING LIGHT AND SHADE.
An object will display the greatest difference of light and shade
when it is seen in the strongest light, as by sunlight, or, at
night, by the light of a fire. But this should not be much used in
painting because the works remain crude and ungraceful.
An object seen in a moderate light displays little difference in the
light and shade; and this is the case towards evening or when the
day is cloudy, and works then painted are tender and every kind of
face becomes graceful. Thus, in every thing extremes are to be
avoided: Too much light gives crudeness; too little prevents our
seeing. The medium is best.
OF SMALL LIGHTS.
Again, lights cast from a small window give strong differences of
light and shade, all the more if the room lighted by it be large,
and this is not good for painting.
517.
PAINTING.
The luminous air which enters by passing through orifices in walls
into dark rooms will render the place less dark in proportion as the
opening cuts into the walls which surround and cover in the
pavement.
518.
OF THE QUALITY OF LIGHT.
In proportion to the number of times that _a b_ goes into _c d_ will
it be more luminous than _c d_. And similarly, in proportion as the
point _e_ goes into _c d_ will it be more luminous than _c d;_ and
this light is useful for carvers of delicate work. [Footnote 5: For
the same reason a window thus constructed would be convenient for an
illuminator or a miniature painter.]
[Footnote: M. RAVAISSON in his edition of the Paris MS. A remarks on
this passage: _"La figure porte les lettres_ f _et_ g, _auxquelles
rien ne renvoie dans l'explication; par consequent, cette
explication est incomplete. La figure semblerait, d'ailleurs, se
rapporter a l'effet de la reflexion par un miroir concave."_ So far
as I can see the text is not imperfect, nor is the sense obscure. It
is hardly necessary to observe that _c d_ here indicate the wall of
the room opposite to the window _e_ and the semicircle described by
_f g_ stands for the arch of the sky; this occurs in various
diagrams, for example under 511. A similar semicircle, Pl III, No. 2
(and compare No. 149) is expressly called '_orizonte_' in writing.]
519.
That the light should fall upon a picture from one window only. This
may be seen in the case of objects in this form. If you want to
represent a round ball at a certain height you must make it oval in
this shape, and stand so far off as that by foreshortening it
appears round.
520.
OF SELECTING THE LIGHT WHICH GIVES MOST GRACE TO FACES.
If you should have a court yard that you can at pleasure cover with
a linen awning that light will be good. Or when you want to take a
portrait do it in dull weather, or as evening falls, making the
sitter stand with his back to one of the walls of the court yard.
Note in the streets, as evening falls, the faces of the men and
women, and when the weather is dull, what softness and delicacy you
may perceive in them. Hence, Oh Painter! have a court arranged with
the walls tinted black and a narrow roof projecting within the
walls. It should be 10 braccia wide and 20 braccia long and 10
braccia high and covered with a linen awning; or else paint a work
towards evening or when it is cloudy or misty, and this is a perfect
light.
On various helps in preparing a picture (521-530).
521.
To draw a nude figure from nature, or any thing else, hold in your
hand a plumb-line to enable you to judge of the relative position
of objects.
522.
OF DRAWING AN OBJECT.
When you draw take care to set up a principal line which you must
observe all throughout the object you are drawing; every thing
should bear relation to the direction of this principal line.
523.
OF A MODE OF DRAWING A PLACE ACCURATELY.
Have a piece of glass as large as a half sheet of royal folio paper
and set thus firmly in front of your eyes that is, between your eye
and the thing you want to draw; then place yourself at a distance of
2/3 of a braccia from the glass fixing your head with a machine in
such a way that you cannot move it at all. Then shut or entirely
cover one eye and with a brush or red chalk draw upon the glass that
which you see beyond it; then trace it on paper from the glass,
afterwards transfer it onto good paper, and paint it if you like,
carefully attending to the arial perspective.
HOW TO LEARN TO PLACE YOUR FIGURES CORRECTLY.
If you want to acquire a practice of good and correct attitudes for
your figures, make a square frame or net, and square it out with
thread; place this between your eye and the nude model you are
drawing, and draw these same squares on the paper on which you mean
to draw the figure, but very delicately. Then place a pellet of wax
on a spot of the net which will serve as a fixed point, which,
whenever you look at your model, must cover the pit of the throat;
or, if his back is turned, it may cover one of the vertebrae of the
neck. Thus these threads will guide you as to each part of the body
which, in any given attitude will be found below the pit of the
throat, or the angles of the shoulders, or the nipples, or hips and
other parts of the body; and the transverse lines of the net will
show you how much the figure is higher over the leg on which it is
posed than over the other, and the same with the hips, and the knees
and the feet. But always fix the net perpendicularly so that all the
divisions that you see the model divided into by the net work
correspond with your drawing of the model on the net work you have
sketched. The squares you draw may be as much smaller than those of
the net as you wish that your figure should be smaller than nature.
Afterwards remember when drawing figures, to use the rule of the
corresponding proportions of the limbs as you have learnt it from
the frame and net. This should be 3 braccia and a half high and 3
braccia wide; 7 braccia distant from you and 1 braccio from the
model.
[Footnote: Leonardo is commonly credited with the invention of the
arrangement of a plate of glass commonly known as the "vertical
plane." Professor E. VON BRUCKE in his _"Bruchstucke aus der Theorie
der bildenden Kunste,"_ Leipzig 1877, pg. 3, writes on this
contrivance. _"Unsere Glastafel ist die sogenannte Glastafel des
Leonardo da Vinci, die in Gestalt einer Glastafel vorgestellte
Bildflache."_]
524.
A METHOD OF DRAWING AN OBJECT IN RELIEF AT NIGHT.
Place a sheet of not too transparent paper between the relievo and
the light and you can draw thus very well.
[Footnote: Bodies thus illuminated will show on the surface of the
paper how the copyist has to distribute light and shade.]
525.
If you want to represent a figure on a wall, the wall being
foreshortened, while the figure is to appear in its proper form, and
as standing free from the wall, you must proceed thus: have a thin
plate of iron and make a small hole in the centre; this hole must be
round. Set a light close to it in such a position as that it shines
through the central hole, then place any object or figure you please
so close to the wall that it touches it and draw the outline of the
shadow on the wall; then fill in the shade and add the lights; place
the person who is to see it so that he looks through that same hole
where at first the light was; and you will never be able to persuade
yourself that the image is not detached from the wall.
[Footnote: _uno piccolo spiracelo nel mezzo_. M. RAVAISSON, in his
edition of MS. A (Paris), p. 52, reads _nel muro_--evidently a
mistake for _nel mezzo_ which is quite plainly written; and he
translates it _"fait lui une petite ouverture dans le mur,"_ adding
in a note: _"les mots 'dans le mur' paraissent etre de trop.
Leonardo a du les ecrire par distraction"_ But _'nel mezzo'_ is
clearly legible even on the photograph facsimile given by Ravaisson
himself, and the objection he raises disappears at once. It is not
always wise or safe to try to prove our author's absence of mind or
inadvertence by apparent difficulties in the sense or connection of
the text.]
526.
TO DRAW A FIGURE ON A WALL 12 BRACCIA HIGH WHICH SHALL LOOK 24
BRACCIA HIGH.
If you wish to draw a figure or any other object to look 24 braccia
high you must do it in this way. First, on the surface _m r_ draw
half the man you wish to represent; then the other half; then put on
the vault _m n_ [the rest of] the figure spoken of above; first set
out the vertical plane on the floor of a room of the same shape as
the wall with the coved part on which you are to paint your figure.
Then, behind it, draw a figure set out in profile of whatever size
you please, and draw lines from it to the point _f_ and, as these
lines cut _m n_ on the vertical plane, so will the figure come on
the wall, of which the vertical plane gives a likeness, and you will
have all the [relative] heights and prominences of the figure. And
the breadth or thickness which are on the upright wall _m n_ are to
be drawn in their proper form, since, as the wall recedes the figure
will be foreshortened by itself; but [that part of] the figure which
goes into the cove you must foreshorten, as if it were standing
upright; this diminution you must set out on a flat floor and there
must stand the figure which is to be transferred from the vertical
plane _r n_[Footnote 17: _che leverai dalla pariete r n_. The
letters refer to the larger sketch, No. 3 on Pl. XXXI.] in its real
size and reduce it once more on a vertical plane; and this will be a
good method [Footnote 18: Leonardo here says nothing as to how the
image foreshortened by perspective and thus produced on the vertical
plane is to be transferred to the wall; but from what is said in
Nos. 525 and 523 we may conclude that he was familiar with the
process of casting the enlarged shadow of a squaring net on the
surface of a wall to guide him in drawing the figure.
_Pariete di rilieuo; "sur une parai en relief"_ (RAVAISSON). _"Auf
einer Schnittlinie zum Aufrichten"_ (LUDWIG). The explanation of
this puzzling expression must be sought in No. 545, lines 15-17.].
[Footnote: See Pl. XXXI. 3. The second sketch, which in the plate is
incomplete, is here reproduced and completed from the original to
illustrate the text. In the original the larger diagram is placed
between lines 5 and 6.
1. 2. C. A. 157a; 463a has the similar heading: '_del cressciere
della figura_', and the text begins: "_Se voli fare 1a figura
grande_ b c" but here it breaks off. The translation here given
renders the meaning of the passage as I think it must be understood.
The MS. is perfectly legible and the construction of the sentence is
simple and clear; difficulties can only arise from the very fullness
of the meaning, particularly towards the end of the passage.]
527.
If you would to draw a cube in an angle of a wall, first draw the
object in its own proper shape and raise it onto a vertical plane
until it resembles the angle in which the said object is to be
represented.
528.
Why are paintings seen more correctly in a mirror than out of it?
529.
HOW THE MIRROR IS THE MASTER [AND GUIDE] OF PAINTERS.
When you want to see if your picture corresponds throughout with the
objects you have drawn from nature, take a mirror and look in that
at the reflection of the real things, and compare the reflected
image with your picture, and consider whether the subject of the two
images duly corresponds in both, particularly studying the mirror.
You should take the mirror for your guide--that is to say a flat
mirror--because on its surface the objects appear in many respects
as in a painting. Thus you see, in a painting done on a flat
surface, objects which appear in relief, and in the mirror--also a
flat surface--they look the same. The picture has one plane surface
and the same with the mirror. The picture is intangible, in so far
as that which appears round and prominent cannot be grasped in the
hands; and it is the same with the mirror. And since you can see
that the mirror, by means of outlines, shadows and lights, makes
objects appear in relief, you, who have in your colours far stronger
lights and shades than those in the mirror, can certainly, if you
compose your picture well, make that also look like a natural scene
reflected in a large mirror.
[Footnote: I understand the concluding lines of this passage as
follows: If you draw the upper half a figure on a large sheet of
paper laid out on the floor of a room (_sala be piana_) to the same
scale (_con le sue vere grosseze_) as the lower half, already drawn
upon the wall (lines 10, 11)you must then reduce them on a '_pariete
di rilievo_,' a curved vertical plane which serves as a model to
reproduce the form of the vault.]
530.
OF JUDGING YOUR OWN PICTURES.
We know very well that errors are better recognised in the works of
others than in our own; and that often, while reproving little
faults in others, you may ignore great ones in yourself. To avoid
such ignorance, in the first place make yourself a master of
perspective, then acquire perfect knowledge of the proportions of
men and other animals, and also, study good architecture, that is so
far as concerns the forms of buildings and other objects which are
on the face of the earth; these forms are infinite, and the better
you know them the more admirable will your work be. And in cases
where you lack experience do not shrink from drawing them from
nature. But, to carry out my promise above [in the title]--I say
that when you paint you should have a flat mirror and often look at
your work as reflected in it, when you will see it reversed, and it
will appear to you like some other painter's work, so you will be
better able to judge of its faults than in any other way. Again, it
is well that you should often leave off work and take a little
relaxation, because, when you come back to it you are a better
judge; for sitting too close at work may greatly deceive you. Again,
it is good to retire to a distance because the work looks smaller
and your eye takes in more of it at a glance and sees more easily
the discords or disproportion in the limbs and colours of the
objects.
On the management of works (531. 532).
531.
OF A METHOD OF LEARNING WELL BY HEART.
When you want to know a thing you have studied in your memory
proceed in this way: When you have drawn the same thing so many
times that you think you know it by heart, test it by drawing it
without the model; but have the model traced on flat thin glass and
lay this on the drawing you have made without the model, and note
carefully where the tracing does not coincide with your drawing, and
where you find you have gone wrong; and bear in mind not to repeat
the same mistakes. Then return to the model, and draw the part in
which you were wrong again and again till you have it well in your
mind. If you have no flat glass for tracing on, take some very thin
kidts-kin parchment, well oiled and dried. And when you have used it
for one drawing you can wash it clean with a sponge and make a
second.
532.
THAT A PAINTER OUGHT TO BE CURIOUS TO HEAR THE OPINIONS OF EVERY ONE
ON HIS WORK.
Certainly while a man is painting he ought not to shrink from
hearing every opinion. For we know very well that a man, though he
may not be a painter, is familiar with the forms of other men and
very capable of judging whether they are hump backed, or have one
shoulder higher or lower than the other, or too big a mouth or nose,
and other defects; and, as we know that men are competent to judge
of the works of nature, how much more ought we to admit that they
can judge of our errors; since you know how much a man may be
deceived in his own work. And if you are not conscious of this in
yourself study it in others and profit by their faults. Therefore be
curious to hear with patience the opinions of others, consider and
weigh well whether those who find fault have ground or not for
blame, and, if so amend; but, if not make as though you had not
heard, or if he should be a man you esteem show him by argument the
cause of his mistake.
On the limitations of painting (533-535)
533.
HOW IN SMALL OBJECTS ERRORS ARE LESS EVIDENT THAN IN LARGE ONES.
In objects of minute size the extent of error is not so perceptible
as in large ones; and the reason is that if this small object is a
representation of a man or of some other animal, from the immense
diminution the details cannot be worked out by the artist with the
finish that is requisite. Hence it is not actually complete; and,
not being complete, its faults cannot be determined. For instance:
Look at a man at a distance of 300 braccia and judge attentively
whether he be handsome or ugly, or very remarkable or of ordinary
appearance. You will find that with the utmost effort you cannot
persuade yourself to decide. And the reason is that at such a
distance the man is so much diminished that the character of the
details cannot be determined. And if you wish to see how much this
man is diminished [by distance] hold one of your fingers at a span's
distance from your eye, and raise or lower it till the top joint
touches the feet of the figure you are looking at, and you will see
an incredible reduction. For this reason we often doubt as to the
person of a friend at a distance.
534.
WHY A PAINTING CAN NEVER APPEAR DETACHED AS NATURAL OBJECTS DO.
Painters often fall into despair of imitating nature when they see
their pictures fail in that relief and vividness which objects have
that are seen in a mirror; while they allege that they have colours
which for brightness or depth far exceed the strength of light and
shade in the reflections in the mirror, thus displaying their own
ignorance rather than the real cause, because they do not know it.
It is impossible that painted objects should appear in such relief
as to resemble those reflected in the mirror, although both are seen
on a flat surface, unless they are seen with only one eye; and the
reason is that two eyes see one object behind another as _a_ and _b_
see _m_ and _n_. _m_ cannot exactly occupy [the space of] _n_
because the base of the visual lines is so broad that the second
body is seen beyond the first. But if you close one eye, as at _s_
the body _f_ will conceal _r_, because the line of sight proceeds
from a single point and makes its base in the first body, whence the
second, of the same size, can never be seen.
[Footnote: This passage contains the solution of the problem
proposed in No. 29, lines 10-14. Leonardo was evidently familiar
with the law of optics on which the construction of the stereoscope
depends. Compare E. VON BRUCKE, _Bruchstucke aus der Theorie der
bildenden Kunste_, pg. 69: "_Schon Leonardo da Vinci wusste, dass
ein noch so gut gemaltes Bild nie den vollen Eindruck der
Korperlichkeit geben kann, wie ihn die Natur selbst giebt. Er
erklart dies auch in Kap. LIII und Kap. CCCXLI_ (ed. DU FRESNE)
_des_ 'Trattato' _in sachgemasser Weise aus dem Sehen mit beiden
Augen_."

WHY OF TWO OBJECTS OF EQUAL SIZE A PAINTED ONE WILL LOOK LARGER THAN
A SOLID ONE.
The reason of this is not so easy to demonstrate as many others.
Still I will endeavour to accomplish it, if not wholly, at any rate
in part. The perspective of diminution demonstrates by reason, that
objects diminish in proportion as they are farther from the eye, and
this reasoning is confirmed by experience. Hence, the lines of sight
that extend between the object and the eye, when they are directed
to the surface of a painting are all intersected at uniform limits,
while those lines which are directed towards a piece of sculpture
are intersected at various limits and are of various lengths. The
lines which are longest extend to a more remote limb than the others
and therefore that limb looks smaller. As there are numerous lines
each longer than the others--since there are numerous parts, each
more remote than the others and these, being farther off,
necessarily appear smaller, and by appearing smaller it follows that
their diminution makes the whole mass of the object look smaller.
But this does not occur in painting; since the lines of sight all
end at the same distance there can be no diminution, hence the parts
not being diminished the whole object is undiminished, and for this
reason painting does not diminish, as a piece of sculpture does.

536.
HOW HIGH THE POINT OF SIGHT SHOULD BE PLACED.
The point of sight must be at the level of the eye of an ordinary
man, and the farthest limit of the plain where it touches the sky
must be placed at the level of that line where the earth and sky
meet; excepting mountains, which are independent of it.
537.
OF THE WAY TO DRAW FIGURES FOR HISTORICAL PICTURES.
The painter must always study on the wall on which he is to picture
a story the height of the position where he wishes to arrange his
figures; and when drawing his studies for them from nature he must
place himself with his eye as much below the object he is drawing
as, in the picture, it will have to be above the eye of the
spectator. Otherwise the work will look wrong.
The apparent size of figures in a picture (538-539)
538.
OF PLACING A FIGURE IN THE FOREGROUND OF A HISTORICAL PICTURE.
You must make the foremost figure in the picture less than the size
of nature in proportion to the number of braccia at which you place
it from the front line, and make the others in proportion by the
above rule.
539.
PERSPECTIVE.
You are asked, O Painter, why the figures you draw on a small scale
according to the laws of perspective do not appear--notwithstanding
the demonstration of distance--as large as real ones--their height
being the same as in those painted on the wall.
And why [painted] objects seen at a small distance appear larger
than the real ones?
The right position of the artist, when painting, and of the
spectator (540-547)
540.
OF PAINTING.
When you draw from nature stand at a distance of 3 times the height
of the object you wish to draw.
541.
OF DRAWING FROM RELIEF.
In drawing from the round the draughtsman should so place himself
that the eye of the figure he is drawing is on a level with his own.
This should be done with any head he may have to represent from
nature because, without exception, the figures or persons you meet
in the streets have their eyes on the same level as your own; and if
you place them higher or lower you will see that your drawing will
not be true.
542.
WHY GROUPS OF FIGURES ONE ABOVE ANOTHER ARE TO BE AVOIDED.
The universal practice which painters adopt on the walls of chapels
is greatly and reasonably to be condemned. Inasmuch as they
represent one historical subject on one level with a landscape and
buildings, and then go up a step and paint another, varying the
point [of sight], and then a third and a fourth, in such a way as
that on one wall there are 4 points of sight, which is supreme folly
in such painters. We know that the point of sight is opposite the
eye of the spectator of the scene; and if you would [have me] tell
you how to represent the life of a saint divided into several
pictures on one and the same wall, I answer that you must set out
the foreground with its point of sight on a level with the eye of
the spectator of the scene, and upon this plane represent the more
important part of the story large and then, diminishing by degrees
the figures, and the buildings on various hills and open spaces, you
can represent all the events of the history. And on the remainder of
the wall up to the top put trees, large as compared with the
figures, or angels if they are appropriate to the story, or birds or
clouds or similar objects; otherwise do not trouble yourself with it
for your whole work will be wrong.
543.
A PICTURE OF OBJECTS IN PERSPECTIVE WILL LOOK MORE LIFELIKE WHEN
SEEN FROM THE POINT FROM WHICH THE OBJECTS WERE DRAWN.
If you want to represent an object near to you which is to have the
effect of nature, it is impossible that your perspective should not
look wrong, with every false relation and disagreement of proportion
that can be imagined in a wretched work, unless the spectator, when
he looks at it, has his eye at the very distance and height and
direction where the eye or the point of sight was placed in doing
this perspective. Hence it would be necessary to make a window, or
rather a hole, of the size of your face through which you can look
at the work; and if you do this, beyond all doubt your work, if it
is correct as to light and shade, will have the effect of nature;
nay you will hardly persuade yourself that those objects are
painted; otherwise do not trouble yourself about it, unless indeed
you make your view at least 20 times as far off as the greatest
width or height of the objects represented, and this will satisfy
any spectator placed anywhere opposite to the picture.
If you want the proof briefly shown, take a piece of wood in the
form of a little column, eight times as high as it is thick, like a
column without any plinth or capital; then mark off on a flat wall
40 equal spaces, equal to its width so that between them they make
40 columns resembling your little column; you then must fix,
opposite the centre space, and at 4 braccia from the wall, a thin
strip of iron with a small round hole in the middle about as large
as a big pearl. Close to this hole place a light touching it. Then
place your column against each mark on the wall and draw the outline
of its shadow; afterwards shade it and look through the hole in the
iron plate.
[Footnote: In the original there is a wide space between lines 3 and
4 in which we find two sketches not belonging to the text. It is
unnecessary to give prominence to the points in which my reading
differs from that of M. RAVAISSON or to justify myself, since they
are all of secondary importance and can also be immediately verified
from the photograph facsimile in his edition.]
544.
A diminished object should be seen from the same distance, height
and direction as the point of sight of your eye, or else your
knowledge will produce no good effect.
And if you will not, or cannot, act on this principle--because as
the plane on which you paint is to be seen by several persons you
would need several points of sight which would make it look
discordant and wrong--place yourself at a distance of at least 10
times the size of the objects.
The lesser fault you can fall into then, will be that of
representing all the objects in the foreground of their proper size,
and on whichever side you are standing the objects thus seen will
diminish themselves while the spaces between them will have no
definite ratio. For, if you place yourself in the middle of a
straight row [of objects], and look at several columns arranged in a
line you will see, beyond a few columns separated by intervals, that
the columns touch; and beyond where they touch they cover each
other, till the last column projects but very little beyond the last
but one. Thus the spaces between the columns are by degrees entirely
lost. So, if your method of perspective is good, it will produce the
same effect; this effect results from standing near the line in
which the columns are placed. This method is not satisfactory unless
the objects seen are viewed from a small hole, in the middle of
which is your point of sight; but if you proceed thus your work will
be perfect and will deceive the beholder, who will see the columns
as they are here figured.
Here the eye is in the middle, at the point _a_ and near to the
columns.
[Footnote: The diagram which stands above this chapter in the
original with the note belonging to it: "a b _e la ripruova_" (_a b_
is the proof) has obviously no connection with the text. The second
sketch alone is reproduced and stands in the original between lines
22 and 23.]
545.
If you cannot arrange that those who look at your work should stand
at one particular point, when constructing your work, stand back
until your eye is at least 20 times as far off as the greatest
height and width of your work. This will make so little difference
when the eye of the spectator moves, that it will be hardly
appreciable, and it will look very good.
If the point of sight is at _t_ you would make the figures on the
circle _d b e_ all of one size, as each of them bears the same
relation to the point _t_. But consider the diagram given below and
you will see that this is wrong, and why I shall make _b_ smaller
than _d e_ [Footnote 8: The second diagram of this chapter stands in
the original between lines 8 and 9.].
It is easy to understand that if 2 objects equal to each other are
placed side by side the one at 3 braccia distance looks smaller than
that placed at 2 braccia. This however is rather theoretical than
for practice, because you stand close by [Footnote 11: Instead of
'_se preso_' (=_sie presso_) M. RAVAISSON reads '_sempre se_' which
gives rise to the unmeaning rendering: '_parceque toujours_ ...'].
All the objects in the foreground, whether large or small, are to be
drawn of their proper size, and if you see them from a distance they
will appear just as they ought, and if you see them close they will
diminish of themselves.
[Footnote 15: Compare No. 526 line 18.] Take care that the vertical
plan on which you work out the perspective of the objects seen is of
the same form as the wall on which the work is to be executed.
546.
OF PAINTING.
The size of the figures represented ought to show you the distance
they are seen from. If you see a figure as large as nature you know
it appears to be close to the eye.
547.
WHERE A SPECTATOR SHOULD STAND TO LOOK AT A PICTURE.
Supposing _a b_ to be the picture and _d_ to be the light, I say
that if you place yourself between _c_ and _e_ you will not
understand the picture well and particularly if it is done in oils,
or still more if it is varnished, because it will be lustrous and
somewhat of the nature of a mirror. And for this reason the nearer
you go towards the point _c_, the less you will see, because the
rays of light falling from the window on the picture are reflected
to that point. But if you place yourself between _e_ and _d_ you
will get a good view of it, and the more so as you approach the
point _d_, because that spot is least exposed to these reflected
rays of light.
III.
THE PRACTICAL METHODS OF LIGHT AND SHADE AND AERIAL PERSPECTIVE.
Gradations of light and shade.
548.
OF PAINTING: OF THE DARKNESS OF THE SHADOWS, OR I MAY SAY, THE
BRIGHTNESS OF THE LIGHTS.
Although practical painters attribute to all shaded objects--trees,
fields, hair, beards and skin--four degrees of darkness in each
colour they use: that is to say first a dark foundation, secondly a
spot of colour somewhat resembling the form of the details, thirdly
a somewhat brighter and more defined portion, fourthly the lights
which are more conspicuous than other parts of the figure; still to
me it appears that these gradations are infinite upon a continuous
surface which is in itself infinitely divisible, and I prove it
thus:--[Footnote 7: See Pl. XXXI, No. 1; the two upper sketches.]
Let _a g_ be a continuous surface and let _d_ be the light which
illuminates it; I say--by the 4th [proposition] which says that that
side of an illuminated body is most highly lighted which is nearest
to the source of light--that therefore _g_ must be darker than _c_
in proportion as the line _d g_ is longer than the line _d c_, and
consequently that these gradations of light--or rather of shadow,
are not 4 only, but may be conceived of as infinite, because _c d_
is a continuous surface and every continuous surface is infinitely
divisible; hence the varieties in the length of lines extending
between the light and the illuminated object are infinite, and the
proportion of the light will be the same as that of the length of
the lines between them; extending from the centre of the luminous
body to the surface of the illuminated object.
On the choice of light for a picture (549-554).
549.
HOW THE PAINTER MUST PLACE HIMSELF WITH REFERENCE TO THE LIGHT, TO
GIVE THE EFFECT OF RELIEF.
Let _a b_ be the window, _m_ the point of light. I say that on
whichever side the painter places himself he will be well placed if
only his eye is between the shaded and the illuminated portions of
the object he is drawing; and this place you will find by putting
yourself between the point _m_ and the division between the shadow
and the light on the object to be drawn.
550.
THAT SHADOWS CAST BY A PARTICULAR LIGHT SHOULD BE AVOIDED, BECAUSE
THEY ARE EQUALLY STRONG AT THE ENDS AND AT THE BEGINNING.
The shadows cast by the sun or any other particular light have not a
pleasing effect on the body to which they belong, because the parts
remain confuse, being divided by distinct outlines of light and
shade. And the shadows are of equal strength at the end and at the
beginning.
551.
HOW LIGHT SHOULD BE THROWN UPON FIGURES.
The light must be arranged in accordance with the natural conditions
under which you wish to represent your figures: that is, if you
represent them in the sunshine make the shadows dark with large
spaces of light, and mark their shadows and those of all the
surrounding objects strongly on the ground. And if you represent
them as in dull weather give little difference of light and shade,
without any shadows at their feet. If you represent them as within
doors, make a strong difference between the lights and shadows, with
shadows on the ground. If the window is screened and the walls
white, there will be little difference of light. If it is lighted by
firelight make the high lights ruddy and strong, and the shadows
dark, and those cast on the walls and on the floor will be clearly
defined and the farther they are from the body the broader and
longer will they be. If the light is partly from the fire and partly
from the outer day, that of day will be the stronger and that of the
fire almost as red as fire itself. Above all see that the figures
you paint are broadly lighted and from above, that is to say all
living persons that you paint; for you will see that all the people
you meet out in the street are lighted from above, and you must know
that if you saw your most intimate friend with a light [on his face]
from below you would find it difficult to recognise him.
552.
OF HELPING THE APPARENT RELIEF OF A PICTURE BY GIVING IT ARTIFICIAL
LIGHT AND SHADE.
To increase relief of a picture you may place, between your figure
and the solid object on which its shadow falls, a line of bright
light, dividing the figure from the object in shadow. And on the
same object you shall represent two light parts which will surround
the shadow cast upon the wall by the figure placed opposite [6]; and
do this frequently with the limbs which you wish should stand out
somewhat from the body they belong to; particularly when the arms
cross the front of the breast show, between the shadow cast by the
arms on the breast and the shadow on the arms themselves, a little
light seeming to fall through a space between the breast and the
arms; and the more you wish the arm to look detached from the breast
the broader you must make the light; always contrive also to arrange
the figures against the background in such a way as that the parts
in shadow are against a light background and the illuminated
portions against a dark background.
[Footnote 6: Compare the two diagrams under No. 565.]
553.
OF SITUATION.
Remember [to note] the situation of your figures; for the light and
shade will be one thing if the object is in a dark place with a
particular light, and another thing if it is in a light place with
direct sunlight; one thing in a dark place with a diffused evening
light or a cloudy sky, and another in the diffused light of the
atmosphere lighted by the sun.
554.
OF THE JUDGMENT TO BE MADE OF A PAINTER'S WORK.
First you must consider whether the figures have the relief required
by their situation and the light which illuminates them; for the
shadows should not be the same at the extreme ends of the
composition as in the middle, because it is one thing when figures
are surrounded by shadows and another when they have shadows only on
one side. Those which are in the middle of the picture are
surrounded by shadows, because they are shaded by the figures which
stand between them and the light. And those are lighted on one side
only which stand between the principal group and the light, because
where they do not look towards the light they face the group and the
darkness of the group is thrown on them: and where they do not face
the group they face the brilliant light and it is their own darkness
shadowing them, which appears there.
In the second place observe the distribution or arrangement of
figures, and whether they are distributed appropriately to the
circumstances of the story. Thirdly, whether the figures are
actively intent on their particular business.
555.
OF THE TREATMENT OF THE LIGHTS.
First give a general shadow to the whole of that extended part which
is away from the light. Then put in the half shadows and the strong
shadows, comparing them with each other and, in the same way give
the extended light in half tint, afterwards adding the half lights
and the high lights, likewise comparing them together.
The distribution of light and shade (556-559)
556.
OF SHADOWS ON BODIES.
When you represent the dark shadows in bodies in light and shade,
always show the cause of the shadow, and the same with reflections;
because the dark shadows are produced by dark objects and the
reflections by objects only moderately lighted, that is with
diminished light. And there is the same proportion between the
highly lighted part of a body and the part lighted by a reflection
as between the origin of the lights on the body and the origin of
the reflections.
557.
OF LIGHTS AND SHADOWS.
I must remind you to take care that every portion of a body, and
every smallest detail which is ever so little in relief, must be
given its proper importance as to light and shade.
558.
OF THE WAY TO MAKE THE SHADOW ON FIGURES CORRESPOND TO THE LIGHT AND
TO [THE COLOUR] OF THE BODY.
When you draw a figure and you wish to see whether the shadow is the
proper complement to the light, and neither redder nor yellower than
is the nature of the colour you wish to represent in shade, proceed
thus. Cast a shadow with your finger on the illuminated portion, and
if the accidental shadow that you have made is like the natural
shadow cast by your finger on your work, well and good; and by
putting your finger nearer or farther off, you can make darker or
lighter shadows, which you must compare with your own.
559.
OF SURROUNDING BODIES BY VARIOUS FORMS OF SHADOW.
Take care that the shadows cast upon the surface of the bodies by
different objects must undulate according to the various curves of
the limbs which cast the shadows, and of the objects on which they
are cast.
The juxtaposition of light and shade (560, 561).
560.
ON PAINTING.
The comparison of the various qualities of shadows and lights not
infrequently seems ambiguous and confused to the painter who desires
to imitate and copy the objects he sees. The reason is this: If you
see a white drapery side by side with a black one, that part of the
white drapery which lies against the black one will certainly look
much whiter than the part which lies against something whiter than
itself. [Footnote: It is evident from this that so early as in 1492
Leonardo's writing in perspective was so far advanced that he could
quote his own statements.--As bearing on this subject compare what
is said in No. 280.] And the reason of this is shown in my [book on]
perspective.
561.
OF SHADOWS.
Where a shadow ends in the light, note carefully where it is paler
or deeper and where it is more or less indistinct towards the light;
and, above all, in [painting] youthful figures I remind you not to
make the shadow end like a stone, because flesh has a certain
transparency, as may be seen by looking at a hand held between the
eye and the sun, which shines through it ruddy and bright. Place the
most highly coloured part between the light and shadow. And to see
what shadow tint is needed on the flesh, cast a shadow on it with
your finger, and according as you wish to see it lighter or darker
hold your finger nearer to or farther from your picture, and copy
that [shadow].
On the lighting of the background (562-565).
562.
OF THE BACKGROUNDS FOR PAINTED FIGURES.
The ground which surrounds the forms of any object you paint should
be darker than the high lights of those figures, and lighter than
their shadowed part: &c.
563.
OF THE BACKGROUND THAT THE PAINTER SHOULD ADOPT IN HIS WORKS.
Since experience shows us that all bodies are surrounded by light
and shade it is necessary that you, O Painter, should so arrange
that the side which is in light shall terminate against a dark body
and likewise that the shadow side shall terminate against a light
body. And by [following] this rule you will add greatly to the
relief of your figures.
564.
A most important part of painting consists in the backgrounds of the
objects represented; against these backgrounds the outlines of
those natural objects which are convex are always visible, and also
the forms of these bodies against the background, even though the
colours of the bodies should be the same as that of the background.
This is caused by the convex edges of the objects not being
illuminated in the same way as, by the same light, the background is
illuminated, since these edges will often be lighter or darker than
the background. But if the edge is of the same colour as the
background, beyond a doubt it will in that part of the picture
interfere with your perception of the outline, and such a choice in
a picture ought to be rejected by the judgment of good painters,
inasmuch as the purpose of the painter is to make his figures appear
detached from the background; while in the case here described the
contrary occurs, not only in the picture, but in the objects
themselves.
565.
That you ought, when representing objects above the eye and on one
side--if you wish them to look detached from the wall--to show,
between the shadow on the object and the shadow it casts a middle
light, so that the body will appear to stand away from the wall.
On the lighting of white objects.
566.
HOW WHITE BODIES SHOULD BE REPRESENTED.
If you are representing a white body let it be surrounded by ample
space, because as white has no colour of its own, it is tinged and
altered in some degree by the colour of the objects surrounding it.
If you see a woman dressed in white in the midst of a landscape,
that side which is towards the sun is bright in colour, so much so
that in some portions it will dazzle the eyes like the sun itself;
and the side which is towards the atmosphere,--luminous through
being interwoven with the sun's rays and penetrated by them--since
the atmosphere itself is blue, that side of the woman's figure will
appear steeped in blue. If the surface of the ground about her be
meadows and if she be standing between a field lighted up by the sun
and the sun itself, you will see every portion of those folds which
are towards the meadow tinged by the reflected rays with the colour
of that meadow. Thus the white is transmuted into the colours of the
luminous and of the non-luminous objects near it.
The methods of aerial (567--570).
567.
WHY FACES [SEEN] AT A DISTANCE LOOK DARK.
We see quite plainly that all the images of visible objects that lie
before us, whether large or small, reach our sense by the minute
aperture of the eye; and if, through so small a passage the image
can pass of the vast extent of sky and earth, the face of a
man--being by comparison with such large images almost nothing by
reason of the distance which diminishes it,--fills up so little of
the eye that it is indistinguishable. Having, also, to be
transmitted from the surface to the sense through a dark medium,
that is to say the crystalline lens which looks dark, this image,
not being strong in colour becomes affected by this darkness on its
passage, and on reaching the sense it appears dark; no other reason
can in any way be assigned. If the point in the eye is black, it is
because it is full of a transparent humour as clear as air and acts
like a perforation in a board; on looking into it it appears dark
and the objects seen through the bright air and a dark one become
confused in this darkness.
WHY A MAN SEEN AT A CERTAIN DISTANCE IS NOT RECOGNISABLE.
The perspective of diminution shows us that the farther away an
object is the smaller it looks. If you look at a man at a distance
from you of an arrow's flight, and hold the eye of a small needle
close to your own eye, you can see through it several men whose
images are transmitted to the eye and will all be comprised within
the size of the needle's eye; hence, if the man who is at the
distance of an arrow's flight can send his whole image to your eye,
occupying only a small space in the needle's eye how can you
[expect] in so small a figure to distinguish or see the nose or
mouth or any detail of his person? and, not seeing these you cannot
recognise the man, since these features, which he does not show, are
what give men different aspects.
568.
THE REASON WHY SMALL FIGURES SHOULD NOT BE MADE FINISHED.
I say that the reason that objects appear diminished in size is
because they are remote from the eye; this being the case it is
evident that there must be a great extent of atmosphere between the
eye and the objects, and this air interferes with the distinctness
of the forms of the object. Hence the minute details of these
objects will be indistinguishable and unrecognisable. Therefore, O
Painter, make your smaller figures merely indicated and not highly
finished, otherwise you will produce effects the opposite to nature,
your supreme guide. The object is small by reason of the great
distance between it and the eye, this great distance is filled with
air, that mass of air forms a dense body which intervenes and
prevents the eye seeing the minute details of objects.
569.
Whenever a figure is placed at a considerable distance you lose
first the distinctness of the smallest parts; while the larger parts
are left to the last, losing all distinctness of detail and outline;
and what remains is an oval or spherical figure with confused edges.
570.
OF PAINTING.
The density of a body of smoke looks white below the horizon while
above the horizon it is dark, even if the smoke is in itself of a
uniform colour, this uniformity will vary according to the variety
in the ground on which it is seen.
IV.
OF PORTRAIT AND FIGURE PAINTING.
Of sketching figures and portraits (571-572).
571.
OF THE WAY TO LEARN TO COMPOSE FIGURES [IN GROUPS] IN HISTORICAL
PICTURES.
When you have well learnt perspective and have by heart the parts
and forms of objects, you must go about, and constantly, as you go,
observe, note and consider the circumstances and behaviour of men in
talking, quarrelling or laughing or fighting together: the action of
the men themselves and the actions of the bystanders, who separate
them or who look on. And take a note of them with slight strokes
thus, in a little book which you should always carry with you. And
it should be of tinted paper, that it may not be rubbed out, but
change the old [when full] for a new one; since these things should
not be rubbed out but preserved with great care; for the forms, and
positions of objects are so infinite that the memory is incapable of
retaining them, wherefore keep these [sketches] as your guides and
masters.
[Footnote: Among Leonardo's numerous note books of pocket size not
one has coloured paper, so no sketches answering to this description
can be pointed out. The fact that most of the notes are written in
ink, militates against the supposition that they were made in the
open air.]
572.
OF A METHOD OF KEEPING IN MIND THE FORM OF A FACE.
If you want to acquire facility for bearing in mind the expression
of a face, first make yourself familiar with a variety of [forms of]
several heads, eyes, noses, mouths, chins and cheeks and necks and
shoulders: And to put a case: Noses are of 10 types: straight,
bulbous, hollow, prominent above or below the middle, aquiline,
regular, flat, round or pointed. These hold good as to profile. In
full face they are of 11 types; these are equal thick in the middle,
thin in the middle, with the tip thick and the root narrow, or
narrow at the tip and wide at the root; with the nostrils wide or
narrow, high or low, and the openings wide or hidden by the point;
and you will find an equal variety in the other details; which
things you must draw from nature and fix them in your mind. Or else,
when you have to draw a face by heart, carry with you a little book
in which you have noted such features; and when you have cast a
glance at the face of the person you wish to draw, you can look, in
private, which nose or mouth is most like, or there make a little
mark to recognise it again at home. Of grotesque faces I need say
nothing, because they are kept in mind without difficulty.
The position of the head.
573.
HOW YOU SHOULD SET TO WORK TO DRAW A HEAD OF WHICH ALL THE PARTS
SHALL AGREE WITH THE POSITION GIVEN TO IT.
To draw a head in which the features shall agree with the turn and
bend of the head, pursue this method. You know that the eyes,
eyebrows, nostrils, corners of the mouth, and sides of the chin, the
jaws, cheeks, ears and all the parts of a face are squarely and
straightly set upon the face.
[Footnote: Compare the drawings and the text belonging to them on
Pl. IX. (No. 315), Pl. X (No. 316), Pl. XL (No. 318) and Pl. XII.
(No. 319).]
Therefore when you have sketched the face draw lines passing from
one corner of the eye to the other; and so for the placing of each
feature; and after having drawn the ends of the lines beyond the two
sides of the face, look if the spaces inside the same parallel lines
on the right and on the left are equal [12]. But be sure to remember
to make these lines tend to the point of sight.
[Footnote: See Pl. XXXI, No. 4, the slight sketch on the left hand
side. The text of this passage is written by the side of it. In this
sketch the lines seem intentionally incorrect and converging to the
right (compare I. 12) instead of parallel. Compare too with this
text the drawing in red chalk from Windsor Castle which is
reproduced on Pl. XL, No. 2.]
Of the light on the face (574-576).
574.
HOW TO KNOW WHICH SIDE OF AN OBJECT IS TO BE MORE OR LESS LUMINOUS
THAN THE OTHER.
Let _f_ be the light, the head will be the object illuminated by it
and that side of the head on which the rays fall most directly will
be the most highly lighted, and those parts on which the rays fall
most aslant will be less lighted. The light falls as a blow might,
since a blow which falls perpendicularly falls with the greatest
force, and when it falls obliquely it is less forcible than the
former in proportion to the width of the angle. _Exempli gratia_ if
you throw a ball at a wall of which the extremities are equally far
from you the blow will fall straight, and if you throw the ball at
the wall when standing at one end of it the ball will hit it
obliquely and the blow will not tell.
[Footnote: See Pl. XXXI. No. 4; the sketch on the right hand side.]
575.
THE PROOF AND REASON WHY AMONG THE ILLUMINATED PARTS CERTAIN
PORTIONS ARE IN HIGHER LIGHT THAN OTHERS.
Since it is proved that every definite light is, or seems to be,
derived from one single point the side illuminated by it will have
its highest light on the portion where the line of radiance falls
perpendicularly; as is shown above in the lines _a g_, and also in
_a h_ and in _l a_; and that portion of the illuminated side will be
least luminous, where the line of incidence strikes it between two
more dissimilar angles, as is seen at _b c d_. And by this means you
may also know which parts are deprived of light as is seen at _m k_.
Where the angles made by the lines of incidence are most equal there
will be the highest light, and where they are most unequal it will
be darkest.
I will make further mention of the reason of reflections.
[Footnote: See Pl. XXXII. The text, here given complete, is on the
right hand side. The small circles above the beginning of lines 5
and 11 as well as the circle above the text on Pl. XXXI, are in a
paler ink and evidently added by a later hand in order to
distinguish the text as belonging to the _Libro di Pittura_ (see
Prolegomena. No. 12, p. 3). The text on the left hand side of this
page is given as Nos. 577 and 137.]

Where the shadow should be on the face.
General suggestions for historical pictures (577-581).
577.
When you compose a historical picture take two points, one the point
of sight, and the other the source of light; and make this as
distant as possible.
578.
Historical pictures ought not to be crowded and confused with too
many figures.
579.
PRECEPTS IN PAINTING.
Let you sketches of historical pictures be swift and the working out
of the limbs not be carried too far, but limited to the position of
the limbs, which you can afterwards finish as you please and at your
leisure.
[Footnote: See Pl. XXXVIII, No. 2. The pen and ink drawing given
there as No. 3 may also be compared with this passage. It is in the
Windsor collection where it is numbered 101.]
580.
The sorest misfortune is when your views are in advance of your
work.
581.
Of composing historical pictures. Of not considering the limbs in
the figures in historical pictures; as many do who, in the wish to
represent the whole of a figure, spoil their compositions. And when
you place one figure behind another take care to draw the whole of
it so that the limbs which come in front of the nearer figures may
stand out in their natural size and place.
How to represent the differences of age and sex (582-583).
582.
How the ages of man should be depicted: that is, Infancy, Childhood,
Youth, Manhood, Old age, Decrepitude.
[Footnote: No answer is here given to this question, in the original
MS.]
583.
Old men ought to be represented with slow and heavy movements, their
legs bent at the knees, when they stand still, and their feet placed
parallel and apart; bending low with the head leaning forward, and
their arms but little extended.
Women must be represented in modest attitudes, their legs close
together, their arms closely folded, their heads inclined and
somewhat on one side.
Old women should be represented with eager, swift and furious
gestures, like infernal furies; but the action should be more
violent in their arms and head than in their legs.
Little children, with lively and contorted movements when sitting,
and, when standing still, in shy and timid attitudes.
[Footnote: _bracci raccolte_. Compare Pl. XXXIII. This drawing, in
silver point on yellowish tinted paper, the lights heightened with
white, represents two female hands laid together in a lap. Above is
a third finished study of a right hand, apparently holding a veil
from the head across the bosom. This drawing evidently dates from
before 1500 and was very probably done at Florence, perhaps as a
preparatory study for some picture. The type of hand with its
slender thin forms is more like the style of the _Vierge aux
Rochers_ in the Louvre than any later works--as the Mona Lisa for
instance.]
Of representing the emotions.
584.
THAT A FIGURE IS NOT ADMIRABLE UNLESS IT EXPRESSES BY ITS ACTION THE
PASSION OF ITS SENTIMENT.
That figure is most admirable which by its actions best expresses
the passion that animates it.
HOW AN ANGRY MAN IS TO BE FIGURED.
You must make an angry person holding someone by the hair, wrenching
his head against the ground, and with one knee on his ribs; his
right arm and fist raised on high. His hair must be thrown up, his
brow downcast and knit, his teeth clenched and the two corners of
his mouth grimly set; his neck swelled and bent forward as he leans
over his foe, and full of furrows.
HOW TO REPRESENT A MAN IN DESPAIR.
You must show a man in despair with a knife, having already torn
open his garments, and with one hand tearing open the wound. And
make him standing on his feet and his legs somewhat bent and his
whole person leaning towards the earth; his hair flying in disorder.
Of representing imaginary animals.
585.
HOW YOU SHOULD MAKE AN IMAGINARY ANIMAL LOOK NATURAL.
You know that you cannot invent animals without limbs, each of
which, in itself, must resemble those of some other animal. Hence if
you wish to make an animal, imagined by you, appear natural--let us
say a Dragon, take for its head that of a mastiff or hound, with the
eyes of a cat, the ears of a porcupine, the nose of a greyhound, the
brow of a lion, the temples of an old cock, the neck of a water
tortoise.
[Footnote: The sketch here inserted of two men on horseback fighting
a dragon is the facsimile of a pen and ink drawing belonging to
BARON EDMOND DE ROTHSCHILD of Paris.]
The selection of forms.
586.
OF THE DELUSIONS WHICH ARISE IN JUDGING OF THE LIMBS.
A painter who has clumsy hands will paint similar hands in his
works, and the same will occur with any limb, unless long study has
taught him to avoid it. Therefore, O Painter, look carefully what
