Heath Wilson obtained legal opinion that Michael Angelo must have been in Florence in person when this deed was executed.

It runs: "In the year of our Lord, 1508, on the 11th day of August, Michael Angelo, the son of Ludovico Lionardo di Buonarroto, cancelled his lawful claim upon the estate of his uncle Francis by a deed drawn up by Ser Giovanni di Guasparre da Montevarchi, Florentine notary, on the 27th of the month of July, 1508." Another instance of Michael Angelo's generosity to his family.

If Michael Angelo at once proceeded to Rome, he and his assistants may have begun work towards the end of August.

During all this period we must notice how troubled he was by the affairs of his family and his household arrangements.

Michael Angelo, while living like a poor man in Rome, sent money to, and purchased land for, his family in Florence, and helped to establish Buonarroto in business, but they were never satisfied, and his letters to his father and Giovan Simone show how his mind was troubled.
There is a letter in the British Museum that belongs to this summer of 1508.
"MOST REVEREND FATHER,--I have learnt by your last how things go with you, and how Giovan Simone behaves himself.
