You will perhaps say that the sinews and muscles of a bird are incomparably more powerful than those of a man... But the reply to this is that such great strength gives it a reserve of power beyond what it ordinarily uses...

Leonardo da Vinci
Oysters open completely when the moon is full; and when the crab sees one it throws a piece of stone or seaweed into it and the oyster cannot close again so that it serves the crab for meat. Such is the fate of him who opens his mouth too much and thereby puts himself at the mercy of the listener.

Leonardo da Vinci
Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.

Leonardo da Vinci
After painting comes Sculpture, a very noble art, but one that does not in the execution require the same supreme ingenuity as the art of painting, since in two most important and difficult particulars, in foreshortening and in light and shade, for which the painter has to invent a process, sculpture is helped by nature. Moreover, Sculpture does not imitate color which the painter takes pains to attune so that the shadows accompany the lights.

Leonardo da Vinci
The atmosphere is blue by reason of the darkness above it because black and white make blue.

Leonardo da Vinci
When that which loves is united to the thing beloved it can rest there; when the burden is laid down it finds rest there. There will be eternal fame also for the inhabitants of that town, constructed and enlarged by him.

Leonardo da Vinci
The vine that has grown old on an old tree falls with the ruin of that tree, and through that bad companionship must perish with it.

Leonardo da Vinci
The body of the atmosphere is full of infinite radiating pyramids produced by the objects existing in it. These intersect and cross each other with independent convergence without interfering with each other and pass through all the surrounding atmosphere; and are of equal force and value — all being equal to each, each to all. And by means of these, images of the body are transmitted everywhere and on all sides, and each receives in itself every minutest portion of the object that produces it.

Leonardo da Vinci
All the elements will be seen mixed together in a great whirling mass, now borne towards the centre of the world, now towards the sky; and now furiously rushing from the South towards the frozen North, and sometimes from the East towards the West, and then again from this hemisphere to the other.

Leonardo da Vinci
The body which is nearest to the light casts the largest shadow, and why? If an object placed in front of a single light is very close to it you will see that it casts a very large shadow on the opposite wall, and the farther you remove the object from the light the smaller will the image of the shadow become.

Leonardo da Vinci
Shadow is the diminution alike of light and of darkness, and stands between darkness and light.

Leonardo da Vinci
Threats alone are the weapons of the threatened man.

Leonardo da Vinci
Nature is full of infinite causes that have never occurred in experience.

Leonardo da Vinci
A bird makes the same use of wings and tail in the air as a swimmer does of his arms and legs in the water.

Leonardo da Vinci
Experience shows us that the air must have darkness beyond it and yet it appears blue. If you produce a small quantity of smoke from dry wood and the rays of the sun fall on this smoke, and if you then place behind the smoke a piece of black velvet on which the sun does not shine, you will see that all the smoke which is between the eye and the black stuff will appear of a beautiful blue colour. And if instead of the velvet you place a white cloth smoke, that is too thick smoke, hinders, and too thin smoke does not produce, the perfection of this blue colour. Hence a moderate amount of smoke produces the finest blue.

Leonardo da Vinci
Men will seem to see new destructions in the sky. The flames that fall from it will seem to rise in it and to fly from it with terror. They will hear every kind of animals speak in human language. They will instantaneously run in person in various parts of the world, without motion. They will see the greatest splendour in the midst of darkness. O! marvel of the human race! What madness has led you thus! You will speak with animals of every species and they with you in human speech. You will see yourself fall from great heights without any harm and torrents will accompany you, and will mingle with their rapid course.

Leonardo da Vinci
Take a piece of glass of the size of a half sheet of royal folio paper, and fix it... between your eye and the object you wish to portray. Then move it away until your eye is two-thirds of a braccio away from the piece of glass, and fasten your head by means of an instrument in such a way as to prevent any movement of it whatsoever. Then close or cover up one eye, and with a brush or a piece of red chalk finely ground mark out on the glass what is visible beyond it; afterwards, copy it by tracing on paper from the glass, then prick it out upon paper of a better quality and paint it if you so desire, paying special attention to the aerial perspective.

Leonardo da Vinci
Obstacles do not bend me. Every obstacle is destroyed through rigor.

Leonardo da Vinci
In many cases one and the same thing is attracted by two strong forces, namely Necessity and Potency. Water falls in rain; the earth absorbs it from the necessity for moisture; and the sun evaporates it, not from necessity, but by its power.

Leonardo da Vinci
He who possesses most must be most afraid of loss.

Leonardo da Vinci
Nature is constrained by the cause of her laws which dwell inborn in her. Variant: Nature is constrained by the order of her own law which lives and works within her.

Leonardo da Vinci
I have found that, in the composition of the human body as compared with the bodies of animals, the organs of sense are duller and coarser. Thus, it is composed of less ingenious instruments, and of spaces less capacious for receiving the faculties of sense.

Leonardo da Vinci
Obstacles cannot crush me. Every obstacle yields to stern resolve. He who is fixed to a star does not change his mind.

Leonardo da Vinci
Darkness is absence of light. Shadow is diminution of light.

Leonardo da Vinci
Like a whirling wind which rushes down a sandy and hollow valley, and which, in its hasty course, drives to its centre every thing that opposes its furious course... No otherwise does the Northern blast whirl round in its tempestuous progress...

Leonardo da Vinci
A luminous body will appear more brilliant in proportion as it is surrounded by deeper shadow.

Leonardo da Vinci
Nothing is that which fills no space. If one single point placed in a circle may be the starting point of an infinite number of lines, and the termination of an infinite number of lines, there must be an infinite number of points separable from this point, and these when reunited become one again; whence it follows that the part may be equal to the whole.

Leonardo da Vinci
What is called Nothingness is to be found only in time and in speech. In time it stands between the past and future and has no existence in the present; and thus in speech it is one of the things of which we say: They are not, or they are impossible.

Leonardo da Vinci
Shadow is the obstruction of light. Shadows appear to me to be of supreme importance in perspective, because, without them opaque and solid bodies will be ill defined; that which is contained within their outlines and their boundaries themselves will be ill-understood unless they are shown against a background of a different tone from themselves.

Leonardo da Vinci
Mechanics is the paradise of the mathematical sciences because by means of it one comes to the fruits of mathematics.
