Note 17 — GOLD AND SILVER WORK.

This is a literal rendering of the text of M. Labarte; but the artists to whom allusion is made were only two, Niccola and Giovanni, sculptors and architects of Pisa. According to Vasari, Niccola, father of Giovanni (Jean or John), first worked under certain Greek sculptors who were executing the figures and other sculptural ornaments of the Duomo of Pisa and the Chapel of San Giovanni.—[Ed.]
