As a well-spent day brings happy sleep, so life well used brings happy death. - Leonardo da Vinci

The abbreviators of works do injury to knowledge and to love.Of what value is he who,in order to abbreviate the parts of those things of which he professes to give complete knowledge,leaves out the greater part of the things of which the whole is composed?Oh human stupidity!You don’t see that you are falling into the same error as one who strips a tree of its adornment of branches full of leaves,intermingled with fragrant flowers or fruit in order to demonstrate that the tree is good for making planks

The eye, which is called the window of the soul, is the principal means by which the central sense can most completely and abundantly appreciate the infinite works of nature; and the ear is the second, which acquires dignity by hearing of the things the eye has seen. If you, historians, or poets, or mathematicians had not seen things with your eyes you could not report of them in writing. And if you, O poet, tell a story with your pen, the painter with his brush can tell it more easily, with simpler completeness and less tedious to be understood. And if you call painting dumb poetry, the painter may call poetry blind painting. Now which is the worse defect? to be blind or dumb? Though the poet is as free as the painter in the invention of his fictions they are not so satisfactory to men as paintings; for, though poetry is able to describe forms, actions and places in words, the painter deals with the actual similitude of the forms, in order to represent them. Now tell me which is the nearer to the actual man: the name of man or the image of the man. The name of man differs in different countries, but his form is never changed but by death.

Art lives from constraints and dies from freedom.
