This is in great measure due to the fact that he was now residing regularly part of the year in Rome and part in Florence.

We have good reason to believe that he went to Rome in September 1532, and stayed there through the winter.

It is probable that he then formed the friendship with Cavalieri, which played so important a part in his personal history.

A brisk correspondence carried on between him and his two friends, Bartolommeo Angelini and Sebastiano del Piombo, shows that he resided at Florence during the summer and early autumn of 1533.

From a letter addressed to Figiovanni on the 15th of October, we learn that he was then impatient to leave Florence for Rome.
