The year 1483--the year of the birth of Raphael and the thirty- first of Leonardo's life--is fixed as the date of his visit to Milan by the letter in which he recommends himself to Ludovico Sforza, and offers to tell him, for a price, strange secrets in the art of war. It was that Sforza who murdered his young nephew by slow poison, yet was so susceptible of religious impressions that he blended mere earthly passion with a sort of religious sentimentalism, and who took for his device the mulberry-tree-- symbol, in its long delay and sudden yielding of flowers and fruit together, of a wisdom which economises all forces for an opportunity of sudden and sure effect. The fame of Leonardo had gone before him, and he was to model a colossal statue of Francesco, the first Duke of Milan. As for Leonardo himself, he came not as an artist at all, or careful of the fame of one; but as a player on the harp, a strange harp of silver of his own construction, shaped in some curious likeness to a horse's skull. The capricious spirit of Ludovico was susceptible also to the power of music, and Leonardo's nature had a kind of spell in it. Fascination is always the word descriptive of him. No portrait of his youth remains; but all tends to make us believe that up to this time some charm of voice and aspect, strong enough to balance the disadvantage of his birth, had [109] played about him. His physical strength was great; it was said that he could bend a horseshoe like a coil of lead.
The Duomo, work of artists from beyond the Alps, so fantastic to the eye of a Florentine used to the mellow, unbroken surfaces of Giotto and Arnolfo, was then in all its freshness; and below, in the streets of Milan, moved a people as fantastic, changeful, and dreamlike. To Leonardo least of all men could there be anything poisonous in the exotic flowers of sentiment which grew there. It was a life of brilliant sins and exquisite amusements: Leonardo became a celebrated designer of pageants; and it suited the quality of his genius, composed, in almost equal parts, of curiosity and the desire of beauty, to take things as they came.
Curiosity and the desire of beauty--these are the two elementary forces in Leonardo's genius; curiosity often in conflict with the desire of beauty, but generating, in union with it, a type of subtle and curious grace.
