So he learned Latin with the man who had taught Dante,--and Dante was admitted to be the most learned man of his times,--and he ground the colours and washed the brushes for Cimabue, and drew under the master's eye everything that he saw, and became, as the chronicler Villani says of him, 'the most sovereign master of painting to be found in his time, and the one who most of all others took all figures and all action from nature.' And Villani was his contemporary, and knew him when he was growing old, and recorded his death and his splendid funeral. One-half of all permanent success in art must always lie in the mechanical part of it, in the understanding and use of the tools. They were primitive in Giotto's day, and even much later, according to our estimate. Oil painting was not dreamt of, nor anything like a lead pencil for drawing. There was no canvas on which to paint. No one had thought of making an artist's palette. Not one-tenth of the substances now used for colours were known then. A modern artist might find himself in great difficulties if he were called upon to paint a picture with Cimabue's tools. But to Giotto they must have seemed marvellous after his pointed stone pencil and his bit of untrimmed slate. Everything must have surprised and delighted him in his first days in Florence--the streets, the houses, the churches, the people, the dresses he saw; and the boy who had begun by copying the sheep that were before his eyes on the hillside, instantly longed to reproduce a thousand things that pleased him. So, when he was already old enough to understand life and its beauty, he was suddenly transported to the midst of it, just where it was most beautiful; and because he instantly saw that his master's art was unreal and far removed from truth, dead, as it were, and bound hand and foot in the graveclothes of Byzantine tradition, his first impulse was to wake the dead in a blaze of life. And this he did. And after him, from time to time, when art seemed to be stiffening again in the clumsy fingers of the little scholars of the great, there came a true artist, like Giotto, who realized the sort of deathlike trance into which art had fallen, and roused it suddenly to things undreamed of--from Giotto to Titian. And each did all that he meant to do. But afterwards came Tintoretto, who said that he would draw like Michelangelo and paint like Titian; but he could not, though he made beautiful things: and he was the first great artist who failed to go farther than others had gone before him; and because art must either advance or go backward, and no one could advance any more, it began to go backward, and the degeneration set in.
