Another Florentine almost equals him in renown. Men watched and whispered when Dante passed through the streets of Florence; but Dante lives in his achievement, Leonardo in himself. Dante means to us an individual soul quivering through a system, a creed, inherited from the past. Leonardo is a spirit unstraitened; not consenting to any past nor rebelling against it, but newborn with a newborn universe around it, seeing it without memories or superstitions, without inherited fears or pieties, yet without impiety or irreverence. He is not an iconoclast, since for him there are no images to be broken; whatever he sees is not an image but itself, to be accepted or rejected by himself; what he would do he does without the help or hindrance of tradition. In art and in science he means the same thing, not a rebirth of any past, as the word Renaissance seems to imply, but freedom from all the past, life utterly in the present. He is concerned not with what has been thought, or said, or done, but with his own immediate relation to all things, with what he sees and feels and discovers. Authority is nothing to him, whether of Galen or of St. Thomas, of Greek or mediæval art. In science he looks at the fact, in art at the object; nor will he allow either to be hidden from him by the achievements of the dead. Giotto had struck the first blow for freedom when he allowed the theme to dictate the picture; Leonardo allowed the object to dictate the drawing. To him the fact itself is sacred, and man fulfils himself in his own immediate relation to fact.

All those who react and rebel against the Renaissance have an easy case against its great representative. What did he do in thought compared with St. Thomas, or in art compared with the builders of Chartres or Bourges? He filled notebooks with sketches and conjectures; he modelled a statue that was never cast; he painted a fresco on a wall, and with a medium so unsuited to fresco that it was a ruin in a few years. Even in his own day there was a doubt about him; it is expressed in the young Michelangelo's sudden taunt that he could not cast the statue he had modelled. Michelangelo was one of those who see in life always the great task to be performed and who judge a man by his performance; to him Leonardo was a dilettante, a talker; he made monuments, but Leonardo remains his own monument, a prophecy of what man shall be when he comes into his kingdom. With him, we must confess, it is more promise than performance; he could paint "The Last Supper" because it means the future; he could never, in good faith, have painted "The Last Judgment," for that means a judgment on the past, and to him the past is nothing; to him man, in the future, is the judge, master, enjoyer of his own fate. Compared with his, Michelangelo's mind was still mediæval, his reproach the reproach of one who cares for doing more than for being, and certainly Michelangelo did a thousand times more; but from his own day to ours the world has not judged Leonardo by his achievement. As Johnson had his Boswell so he has had his legend; he means to us not books or pictures, but himself. In his own day kings bid for him as if he were a work of art; and he died magnificently in France, making nothing but foretelling a race of men not yet fulfilled.

Before Francis Bacon, before Velasquez or Manet, he prophesied not merely the new artist or the new man of science, but the new man who is to free himself from his inheritance and to see, feel, think, and act in all things with the spontaneity of God. That is why he is a legendary hero to us, with a legend that is not in the past but in the future. For his prophecy is still far from fulfilment; and the very science that he initiated tells us how hard it is for man to free himself from his inheritance. It seems strange to us that Leonardo sang hymns to causation as if to God. In its will was his peace and his freedom.

O marvellous necessity, thou with supreme reason constrainest all efforts to be the direct result of their causes, and by a supreme and irrevocable law every natural action obeys thee by the shortest possible process.

Who would believe that so small a space could contain the images of all the universe? O mighty process, what talent can avail to penetrate a nature such as thine? What tongue will it be that can unfold so great a wonder? Verily none. This it is that guides the human discourse to the considering of divine things.[1]

To Leonardo causation meant the escape from caprice; it meant a secure relation between man and all things, in which man would gain power by knowledge, in which every increase of knowledge would reveal to him more and more of the supreme reason. There was no chain for him in cause and effect, no unthinking of the will of man. Rather by knowledge man would discover his own will and know that it was the universal will. So man must never be afraid of knowledge. "The eye is the window of the soul." Like Whitman he tells us always to look with the eye, and so to confound the wisdom of ages. There is in every man's vision the power of relating himself now and directly to reality by knowledge; and in knowing other things he knows himself. By knowledge man changes what seemed to be a compulsion into a harmony; he gives up his own caprice for the universal will.

That is the religion of Leonardo, in art as in science. For him the artist also must relate himself directly to the visible world, in which is the only inspiration; to accept any formula is to see with dead men's eyes. That has been said again and again by artists, but not with Leonardo's mystical and philosophical conviction. He knew that it is vain to study Nature unless she is to you a goddess or a god; you can learn nothing from reality unless you adore it, and in adoring it he found his freedom. How different is this doctrine from that with which, after centuries of scientific advance, we intimidate ourselves. We are threatened by a creed far more enslaving than that of the Middle Ages. If the Middle Ages turned to the past to learn what they were to think or to do, we turn to the past to learn what we are. They may have feared the new; but we say that there is no new, nothing but some combination or variation of the old. Causation is to us a chain that binds us to the past, but to Leonardo it was freedom; and so he prophesies a freedom that we may attain to not by denying facts or making myths, but by discovering what he hinted—that causation itself is not compulsion but will, and our will if, by knowledge, we make it ours.

No one before him had been so much in love with reality, whatever it may be. He was called a sceptic, but it was only that he preferred reality itself to any tales about it; and his religion, his worship, was the search for the very fact. This, because he was both artist and man of science, he carried further than anyone else, pursuing it with all his faculties. In his drawings there is the beauty not of his character, but of the character of what he draws; he does not make a design, but finds it. That beauty proves him a Florentine—Dürer himself falls short of it—but it is the beauty of the thing itself, discovered and insisted upon with the passion of a lover. He draws animals, trees, flowers, as Correggio draws Antiope or Io; and it is only in his drawings now that he speaks clearly to us. The "Mona Lisa" is well enough, but another hand might have executed the painting of it. It owes its popular fame to the smile about which it is so easy to write finely; but in the drawings we see the experiencing passion of Leonardo himself, we see him feeling, as in the notebooks we see him thinking. There is the eagerness of discovery at which so often he stopped short, turning away from a task to further discovery, living always in the moment, taking no thought either for the morrow or for yesterday, unable to attend to any business, even the business of the artist, seeing life not as a struggle or a duty, but as an adventure of all the senses and all the faculties. He is, even with his pencil, the greatest talker in the world, but without egotism, talking always of what he sees, satisfying himself not with the common appetites and passions of men, but with his one supreme passion for reality. If Michelangelo thought him a dilettante, there must have been in his taunt some envy of Leonardo's freedom.
