Learning acquired in youth arrests the evil of old age; and if you understand that old age has wisdom for its food, you will so conduct yourself in youth that your old age will not lack for nourishment. (Leonardo da Vinci)
I love those who can smile in trouble, who can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink, but they whose heart is firm, and whose conscience approves their conduct, will pursue their principles unto death. View quote

Small rooms or dwellings discipline the mind, large ones weaken it. View quote

Painting is poetry which is seen and not heard, and poetry is a painting which is heard but not seen. These two arts, you may call them both either poetry or painting, have here interchanged the senses by which they penetrate to the intellect. View quote

The water of the river you touch is the last of the one that went and the first of the one that comes. Thus the present tense. (referring to the movements underlying the mountains around Lierna and the Fiumelatte connected to the Moncodeno cave) View quote
Leonardo da Vinci
At once two things came to mind: fear and desire: fear of the threatening dark cave, desire to see if there was anything miraculous within it.(referring to the "Cave of Acquabianca" or "La Ferrera" on Lake Comuntain). View quote
Leonardo da Vinci
Opposite to Bellagio is the Fiumelatte, which falls from over 100 meters from the source where it is born, plumb over the lake, with inestimable clamor and noise. This vein of water pours only in August and September. View quote

Grigna is the highest mountain I've seen in these countries, and it's bald. View quote
Leonardo da Vinci
Those men who are inventors and interpreters between Nature and Man, as compared with boasters and declaimers of the works of others, must be regarded and not otherwise esteemed than as the object in front of a mirror, when compared with its image seen in the mirror. For the first is something in itself, and the other nothingness. - Folks little indebted to Nature, since it is only by chance that they wear the human form and without it I might class them with the herds of beasts. (Leonardo da Vinci)
The eye - which sees all objects reversed - retains the images for some time. This conclusion is proved by the results; because, the eye having gazed at light retains some impression of it. After looking (at it) there remain in the eye images of intense brightness, that make any less brilliant spot seem dark until the eye has lost the last trace of the impression of the stronger light.

The boundaries of bodies are the least of all things. The proposition is proved to be true, because the boundary of a thing is a surface, which is not part of the body contained within that surface; nor is it part of the air surrounding that body, but is the medium interposted between the air and the body, as is proved in its place. View quote
Leonardo da Vinci
The air is filled with endless images of the objects distributed in it; and all are represented in all, and all in one, and all in each, whence it happens that if two mirrors are placed in such a manner as to face each other exactly, the first will be reflected in the second and the second in the first. The first being reflected in the second takes to it the image of itself with all the images represented in it, among which is the image of the second mirror, and so, image within image, they go on to infinity in such a manner as that each mirror has within it a mirror, each smaller than the last and one inside the other. Thus, by this example, it is clearly proved that every object sends its image to every spot whence the object itself can be seen; and the converse: That the same object may receive in itself all the images of the objects that are in front of it.

Shadow is not the absence of light, merely the obstruction of the luminous rays by an opaque body. Shadow is of the nature of darkness. Light is of the nature of a luminous body; one conceals and the other reveals. They are always associated and inseparable from all objects. But shadow is a more powerful agent than light, for it can impede and entirely deprive bodies of their light, while light can never entirely expel shadow from a body, that is from an opaque body. View quote
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
A picture or representation of human figures, ought to be done in such a way as that the spectator may easily recognise, by means of their attitudes, the purpose in their minds. Thus, if you have to represent a man of noble character in the act of speaking, let his gestures be such as naturally accompany good words; and, in the same way, if you wish to depict a man of a brutal nature, give him fierce movements; as with his arms flung out towards the listener, and his head and breast thrust forward beyond his feet, as if following the speaker's hands. Thus it is with a deaf and dumb person who, when he sees two men in conversation - although he is deprived of hearing - can nevertheless understand, from the attitudes and gestures of the speakers, the nature of their discussion.

Leonardo da Vinci
Experience does not err; only your judgments err by expecting from her what is not in her power. Men wrongly complain of Experience; with great abuse they accuse her of leading them astray but they set Experience aside, turning from it with complaints as to our ignorance causing us to be carried away by vain and foolish desires to promise ourselves, in her name, things that are not in her power; saying that she is fallacious. Men are unjust in complaining of innocent Experience, constantly accusing her of error and of false evidence. View quote
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. View quote
Leonardo da Vinci
He who suffers time to slip away and does not grow in virtue the more one thinks about him the sadder one becomes. No man has a capacity for virtue who sacrifices honour for gain. Fortune is powerless to help one who does not exert himself. That man becomes happy who follows Christ. There is no perfect gift without great suffering. Our triumphs and our pomps pass away; gluttony and sloth and enervating luxury have banished every virtue from the world; so that as it were wandering from its course our nature is subdued by habit. Now and henceforth it is meet that you cure yourself of laziness. The Master has said that sitting on down or lying under the quilts will not bring thee to fame. He who without it has frittered life away leaves no more trace of himself upon the earth than smoke does in the air or the foam on the water. View quote
Leonardo da Vinci
Knowing is not enough; we must apply. Being willing is not enough; we must do. (Leonardo da Vinci)
