forces in his genius; curiosity often in conflict with the desire of beauty, but generating, in union with it, a type of subtle and curious grace.
The movement of the fifteenth century was twofold; partly the Renaissance, partly also the coming of what is called the "modern spirit," with its realism, its appeal to experience: it comprehended a return to antiquity, and a return to nature. Raphael represented the return to antiquity, and Leonardo the return to nature. In this return to nature, he was seeking to satisfy a boundless curiosity by her perpetual surprises, a microscopic sense of finish by her finesse, or delicacy of operation, that subtilitas naturae which Bacon notices. His observations and experiments fill thirteen volumes of manuscript; and those who can judge describe him as anticipating long before, by rapid intuition, the later ideas of science.
He who thus penetrated into the most secret parts of nature preferred always the more to the less remote, what, seeming exceptional, was an instance of law more refined, the construction about things of a peculiar atmosphere and mixed lights. In him first appears the taste for what is bizarre or recherché in landscape, hollow places full of the green shadow of bituminous rocks, ridged reefs of trap-rock, which cut the water into quaint sheets of light—their exact antitype is in our own western seas; all the solemn effects of moving water. His landscape is the landscape, not of dreams or of fancy, but of places far withdrawn, and hours selected from a thousand with a miracle of finesse. Through Leonardo's strange veil of sight things reach him so; in no ordinary night or day, but as in faint light of eclipse, or in some brief interval of falling rain at daybreak, or through deep water.
And not into nature only; but he plunged also into human personality, and became above all a painter of portraits: faces of a modelling more skilful than has been seen before or since, embodied with a reality which almost amounts to illusion, on dark air. To take a character as it was, and delicately sound its stops, suited one so curious in observation, curious in invention.
Sometimes this curiosity came in conflict with the desire of beauty; it tended to make him go too far below that outside of things in which art begins and ends. This struggle between the reason and its ideas, and the senses, the desire of beauty, is the key to Leonardo's life at Milan—his restlessness, his endless re-touchings, his odd experiments with color. How much must he leave unfinished, how much recommence! His problem was the transmutation of ideas into images. What he had attained so far had been the mastery of that earlier Florentine style, with its naive and limited sensuousness. Now he was to entertain in this narrow medium those divinations of a humanity too wide for it, that larger vision of the opening world, which is only not too much for the great, irregular art of Shakespeare.

THE world, perhaps, contains no example of a genius so universal as Leonardo's, so creative, so incapable of self-contentment, so athirst for the infinite, so naturally refined, so far in advance of his own and of subsequent ages. His countenances express incredible sensibility and mental
