Among these, says Vasari, were his friends Francesco Granacci and Giuliano Bugiardini, Bastiano da San Gallo surnamed Aristotele, Angelo di Donnino, Jacopo di Sandro, and Jacopo surnamed l'Indaco.

Vasari is probably accurate in his statement here; for we shall see that Michelangelo, in his _Ricordi_, makes mention of five assistants, two of whom are proved by other documents to have been Granacci and Indaco.

We also possess two letters from Granacci which show that Bugiardini, San Gallo, Angelo di Donnino, and Jacopo l'Indaco were engaged in July.

The second of Granacci's letters refers to certain disputes and hagglings with the artists.

This may have brought Michelangelo to Florence, for he was there upon the 11th of August 1508, as appears from the following deed of renunciation: "In the year of our Lord 1508, on the 11th day of August, Michelangelo, son of Lodovico di Lionardo di Buonarrota, repudiated the inheritance of his uncle Francesco by an instrument drawn up by the hand of Ser Giovanni di Guasparre da Montevarchi, notary of Florence, on the 27th of July 1508." When the assistants arrived at Rome is not certain.
