Arezzo, who learned design from Agnolo and Agostino of Siena, were the first who executed great works of any excellence with the chisel; for they made for the head priest of the Pieve of Arezzo a silver head of life-size, in which was put the head of St Donato, bishop and protector of that city, a work which was certainly praiseworthy, if only because they introduced into it some figures in enamel, which were, as I have said, among the first things executed with the chisel. About the same time, or shortly before, the art of the Calimara at Florence, entrusted to Master Cione, an excellent goldsmith, the greater part, if not the whole, of the silver altar of S. Giovanni Batista, which contains many scenes from the life of that saint, engraved in a very creditable manner on a silver plate. This work, on account of its dimensions, and the novelty of its execution, was considered marvellous by everyone who saw it. The same Master Cione, in 1330, when the body of St Zenobius was found under the vaults of St Reparata, placed in a silver head of life-size, the piece of the head of that saint which is still preserved therein, and is carried in procession. This head was considered a most beautiful thing at the time, and brought much reputation to the artist, who died soon after, a wealthy man, and held in high esteem. Master Cione left many pupils, and among others, Forzore di Spinello of Arezzo, who did all manner of engraving excellently, but was especially good in making scenes in enamel on silver, such as may be seen in the Vescovado at Arezzo, for which he made a mitre with a beautiful border of enamel, and a fine pastoral staff in silver. He also executed many things in silver for the Cardinal Galeotto da Pietramala, who bequeathed them to the friars of la Vernia, where he wished to be buried, and where, besides the wall, which the Count Orlando, lord of Chiusi, a small castle below la Vernia, had caused to be set up, he built the church and many rooms in the convent, and all this without leaving any notice or other memorial of himself in any part of that place. Another pupil of Master Cione was Lionardo di Ser Giovanni of Florence, who executed a number of works with the chisel and with solder, with a better design than those who preceded him, especially the altar and silver bas-reliefs of S. Jacopo at Pistoia, where, beside a large number of subjects, the half-length figure of St James, more than a braccia high, is much admired. It is in full relief, and finished with such elaboration, that it seems to have been cast rather than engraved. The figure is placed in the midst of the scenes of the altar table, about which runs a legend in letters of enamel: Ad honorem Dei et S. Jacobi Apostoli, hoc opus factum fuit tempore Domini Franc.
