After the demise of Raffaello, legislation in Art was no longer disputed with M. Angelo; he not only became the oracle of youth, but appears to have inherited all the popularity of his great rival. A signal, though little known proof of this, is told by Bellori, in the Life of Federigo Barrocci, who, he says, used to tell, that when, drawing one day in company with Taddeo Zuccari a frieze of Polidoro, Michael Angelo, as usual, passed by on his little mule on his way to the palace, all the youths rose and ran to meet him with their drawings in their hands; Federigo alone remained bashfully behind in his place, which when Taddeo saw, he took his little portfolio to Michael Angelo, who attentively examined the designs, among which was a careful copy of his Moses; he praised it, and desiring to see the lad who had drawn that figure, animated him to pursue the method of study which he had begun. The deference which he paid to the unassuming and the humble, he amply redeemed by the full assumption of his rights, and conscious assertion of superiority, when provoked to the contest by those who considered themselves as his equals, entered into competition with him, or attempted to share in his labours. Thus he repaid the sarcasms of Pietro Perugino, by calling him publicly a dunce in art; and when Pietro smarting, impatient of the ridicule, summoned him to the Tribunal of the Eight, he made good his charge, and saw him dismissed with contempt. Thus he rejected all partnership with Jacopo Sansovino, in the execution of the Facciata of San Lorenzo at Florence, though Leone X. appears to have intended it, by sending both together to Pietra Santa to provide the marbles necessary for that purpose, and examining both their models. When Paolo III. had resolved on the fortifications of the Borgo, and, in order to ascertain the best mode of doing it, had assembled many persons of rank, with Antonio da Sangallo, Michael Angelo, as architect of the fortifications of S. Miniato at Florence, was likewise invited to join the assembly, and, after much contest, his opinion asked; he freely told it, though contrary to that of Sangallo and others present; and when the architect bade him to be content with the prerogatives of sculpture and painting without pretending to skill in fortification, he replied, that of the former two he knew little, but that of fortification, considering the time his mind had dwelt on it, and the proofs he had given of the solidity of his theory, he did not hesitate to claim more knowledge than what came to the share of Sangallo and all his relatives; and then proceeded, in the presence of all, to point out the many errors which Antonio had committed.
