When the contract with Francesco Pellicia was cancelled, April 7, 1517, the project for developing the Florentine stone-quarries does not seem to have taken shape. We must assume, therefore, that the motive for this step was the abandonment of the tomb. The Ricordi show that Michelangelo was still buying marbles and visiting Carrara down to the end of February 1518. His correspondence from Pietra Santa and Serravezza, where he lived when he was opening the Florentine quarries of Monte Altissimo, does not begin, with any certainty, until March 1518. We have indeed one letter written to Girolamo del Bardella of Porto Venere upon the 6th of August, without date of year. This was sent from Serravezza, and Milanesi, when he first made use of it, assigned it to 1517. Gotti, following that indication, asserts that Michelangelo began his operations at Monte Altissimo in July 1517; but Milanesi afterwards changed his opinion, and assigned it to the year 1519. I believe he was right, because the first letter, bearing a certain date from Pietra Santa, was written in March 1518 to Pietro Urbano. It contains the account of Michelangelo’s difficulties with the Carraresi, and his journey to Genoa and Pisa. We have, therefore, every reason to believe that he finally abandoned Carrara, for Pietra Santa at the end of February 1518.
Pietra Santa is a little city on the Tuscan seaboard; Serravezza is a still smaller fortress-town at the foot of the Carrara mountains. Monte Altissimo rises above it; and on the flanks of that great hill lie the quarries Della Finocchiaja, which Michelangelo opened at the command of Pope Leo. It was not without reluctance that Michelangelo departed from Carrara, offending the Marquis Malaspina, breaking
