Fire destroys all sophistry, that is deceit; and maintains truth alone, that is gold.

As a day well spent procures a happy sleep, so a life well employed procures a happy death.

Here forms, here colours, here the character of every part of the universe are concentrated to a point; and that point is so marvellous a thing … Oh! marvellous, O stupendous Necessity - by thy laws thou dost compel every effect to be the direct result of its cause, by the shortest path. These are miracles...
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

The lover is moved by the beloved object as the senses are by sensual objects; and they unite and become one and the same thing. The work is the first thing born of this union; if the thing loved is base the lover becomes base.

Necessity is the mistress and guide of nature.

Truth at last cannot be hidden. Dissimulation is of no avail. Dissimulation is to no purpose before so great a judge. Falsehood puts on a mask. Nothing is hidden under the sun.

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.
Leonardo da Vinci
-
Painting embraces and contains within itself all the things which nature produces or which results from the fortuitous actions of men... he is but a poor master who makes only a single figure well.
Leonardo da Vinci

A shadow may be infinitely dark, and also of infinite degrees of absence of darkness. The beginnings and ends of shadow lie between the light and darkness and may be infinitely diminished and infinitely increased. Shadow is the means by which bodies display their form. The forms of bodies could not be understood in detail but for shadow.
Leonardo da Vinci
-
The spirit has no voice, because where there is a voice there is a body, and where there is a body space is occupied, and this prevents the eye from seeing what is placed behind that space; hence the surrounding air is filled by the body, that is by its image.
Leonardo da Vinci
-
Wherever good fortune enters, envy lays siege to the place and attacks it; and when it departs, sorrow and repentance remain behind.
Leonardo da Vinci
-
That is not riches, which may be lost; virtue is our true good and the true reward of its possessor. That cannot be lost; that never deserts us, but when life leaves us. As to property and external riches, hold them with trembling; they often leave their possessor in contempt, and mocked at for having lost them.
Leonardo da Vinci
-
Chi non punisce il male comanda che si faccia.
Leonardo da Vinci
-
Men born in hot countries love the night because it refreshes them and have a horror of light because it burns them; and therefore they are of the colour of night, that is black. And in cold countries it is just the contrary.
Leonardo da Vinci
-
Men are in error when they lament the flight of time, accusing it of being too swift, and not perceiving that it is sufficient as it passes; but good memory, with which nature has endowed us, causes things long past to seem present.
Leonardo da Vinci
-
The properties of the air are such that it may become condensed or rarefied.
Leonardo da Vinci
-
A shadow will appear dark in proportion to the brilliancy of the light surrounding it and conversely it will be less conspicuous where it is seen against a darker background.
Leonardo da Vinci
