Baccio's calm devotional mind no doubt disliked the turmoil of this garden, crowded with spirited youths; the tone of pagan art was not in accordance with his ideal, and so he learned from Masaccio and Lippi that love of true form and harmonious composition, which he perfected afterwards by a close study of Leonardo da Vinci, whose principles of _chiaroscuro_ he seems to have completely carried out. With this training he rose to such great celebrity even in his early manhood, that Rosini [Footnote: Rosini, _Storia della Pittura_, chap. xvii. p. 48.] calls him "the star of the Florentine school in Leonardo and Michelangelo's absence," and he attained a grandeur almost equal to the latter, in the S. Mark and SS. Peter and Paul of his later years. Meanwhile Mariotto was revelling in the Eden of art, drawing daily beneath the Loggie--where the orange-trees grew close to the pillars--from the exquisite statues and "torsi," peopling the shades with white forms, or copying cartoons by the older masters, which hung against the walls. The _custode_ of all these treasures was Bertoldo, an old sculptor, who boasted of having been the scholar of Donatello, and also heir to his art possessions. He could also point to the bronze pulpits of San Lorenzo, which he finished, as proof of his having inherited a portion of his master's spirit. Bertoldo, having doubtless rendered to Duke Cosimo's keeping his designs by Donatello, which were preserved in the garden, obtained the post of instructor there; but his age may have prevented his keeping perfect order, and the younger spirits overpowered him. There were Michelangelo, with all the youthful power of passion and force which he afterwards imparted to his works, and the audacious Torrigiano, with his fierce voice, huge bulk, and knitted brows, who was himself a discord like the serpent in Eden. Easily offended, he was prompt in offering outrage. Did any other young man show talent or surpass him, revenge deep and mean as that of Bandinelli to Michelangelo was sure to follow, the envied work being spoiled in his rage. Then there were the fun-loving Francesco Granacci, and the witty Rustici, as full of boyish pranks as they were of genius--what could one old man do among so many?--and now comes the impetuous Mariotto to add one more unruly member to his class. How well one can imagine the young men--in loose blouses confined at the waist, or in buff jerkins and close-fitting hose, with jaunty cloaks or doublets, and little red or black caps, set on flowing locks cut square in front--passing beneath the shadows of the arches among the dim statues, or crossing the garden in the sunshine amid the orange-trees, under the splendid blue Italian skies.
