The Baptist is very often shown on altarpieces designed for churches dedicated to him, or where the donor patron was named for him or there was some other patronage connection. John the Baptist is the patron saint of Florence and has often been depicted in the art of that city, and also frequently appears in baptistries, which are very often dedicated to him. Major works depicting St. John the Baptist can be found in the Baptistry (the mosaics on the vault, the bronze doors by Andrea Pisano, and the great silver altar now in the Museo dell'Opera del Duomo) in the frescoes by Giotto for the in the church of Santa Croce, those by Filippo Lippi in the cathedral of Prato and, the frescoes by Ghirlandaio for the Chancel, or Tornabuoni Chapel in Santa Maria Novella.
