to Luca Martini. While Piero was thus working in Rome, and was occupied with the labours of which we have spoken, Luca Martini was appointed by the Duke of Florence to be Proveditore of Pisa, and in his new office he did not forget his friend, but wrote to him, on the contrary, telling him that he was preparing an abode for his reception, and had a piece of marble of three braccia ready for him to commence working on, so that he might return at his pleasure, seeing that he should want for nothing while he would remain with him.
Attracted by this promise and by the love which he bore to Luca, Piero determined to leave Rome and to make Pisa his dwelling place for some time, thinking he might there find opportunities for the exercise of his vocation, and the desired occasion for making trial of his ability.
