Artists: this is a precise, highly mathematic book! Must be read and studied slowly, as Davinci has observed the world around him with painstaking care. In Chapter 74, for instance, I’ve no doubt he made a model walk against wind currents for hours… and just took notes.
Curious about how many cadavers he had access to, as his knowledge on subcutaneous tissues is massive. Most revealingly, he credits all artistic genius not to talent… but to consistent effort.

“Many are very desirous of learning to draw, and are very fond of it, who are, notwithstanding, void of a proper disposition for it. This may be known by their want of perseverance.”
“When you draw from Nature, you must be at the distance of three times the height of the object.”
“It reflects no great honor on a painter to be able to execute only one thing well… there is scarcely a person so void of genius as to fail of success, if he apply earnestly to one branch of study, and practice it continually.”
"A man has the greatest power in pulling, for in that action he has the united exertion of all the muscles of the arm, while some of them must be inactive when he is pushing."
"A man walking will always have the centre of gravity over the centre of the leg which rests upon the ground."
"That figure will appear the swiftest in its course which leans the most forwards."
"Perspective is to painting what the bridle is to a horse, and the rudder to a ship."
"A painter ought to aim at universal excellence; for he will be greatly wanting in dignity, if he do one thing well and another badly, as many do…"
"The painter ought always to form in his mind a kind of system of reasoning or discussion within himself on any remarkable object before him. He should stop, take notes, and form some rule upon it; considering the place, the circumstances, the lights and shadows."
"A painter should delight in introducing great variety into his compositions, avoiding repetition, that by this fertility of invention he may attract and charm the eye of the beholder."
"Observe decorum in every thing you represent, that is, fitness of action, dress, and situation, according to the dignity or meanness of the subject to be represented. "
"Old men must have slow and heavy motions… Old women, on the contrary, are to be represented bold and quick, with passionate motions."
"The painter who wishes to be universal, and please a variety of judges, must unite in the same composition, objects susceptible of great force in the shadows, and great sweetness in the management of them; accounting, however, in every instance, for such boldness and softenings."
"When you have acquired the habit, and formed your hand to accuracy, quickness of execution will come of itself."
"Those shadows which in Nature are undetermined, and the extremities of which can hardly be perceived, are to be copied in your painting in the same manner, never to be precisely finished, but left confused and blended. This apparent neglect will shew great judgment, and be the ingenious result of your observation of Nature."
"You must not mark any muscles with hardness of line, but let the soft light glide upon them, and terminate imperceptibly in delightful shadows: from this will arise grace and beauty to the face."
"Observe also, that snow appears to fall very quick and in a great quantity when near the eye; but when at some distance, it seems to come down slowly, and in a smaller quantity."
"Polished and glossy surfaces show least of their genuine colour. This is exemplified in the grass of the fields, and the leaves of trees, which, being smooth and glossy, will reflect the colour of the sun, and the air, where they strike, so that the parts which receive the light do not show their natural color."
"The lights are of two sorts; one is called original, the other derivative. The original light is that which comes from the sun, or the brightness of fire, or else from the air. The derivative is a reflected light."
"The only portion of air that will be seen reflected in the water, will be that which is reflected by the surface of the water to the eye between equal angles; that is to say, the angle of incidence must be equal to the angle of reflection."
"Objects appear smaller than they really are when they are distant from the eye…"
"It is evident that the air is in some parts thicker and grosser than in others, particularly that nearest to the earth; and as it rises higher, it becomes thinner and more transparent."
"A painter cannot be said to aim at universality in the art, unless he love equally every species of that art."
"One painter ought never to imitate the manner of any other; because in that case he cannot be called the child of Nature, but the grandchild. It is always best to have recourse to Nature, which is replete with such abundance of objects, than to the productions of other masters, who learnt every thing from her."
"If you excuse yourself by saying that you have not time for the study necessary to form a great painter, having to struggle against necessity, you yourself are only to blame; for the study of what is excellent is food both for mind and body. "
"We should derive more advantage from having our faults pointed out by our enemies, than by hearing the opinions of our friends, because they are too much like ourselves, and may deceive us as much as our own judgment."
"A painter ought to study universal Nature, and reason much within himself on all he sees, making use of the most excellent parts that compose the species of every object before him. His mind will by this method be like a mirror, reflecting truly every object placed before it, and become, as it were, a second Nature."
"The painter who entertains no doubt of his own ability will attain very little. "
