Interior view

founded 1316
Baptistery, Siena

The interior is a rectangular hall, divided into a nave and two aisles by two columns. It contains a hexagonal baptismal font in bronze, marble and vitreous enamel, realized in 1417-1431 by the main sculptors of the time: Donatello, Lorenzo Ghiberti, Giovanni di Turino, Goro di Neroccio and Jacopo della Quercia. The panels of the baptismal font represent the Life of John the Baptist, and include: the Annunciation to Zacharias by Jacopo della Quercia; the Birth of John the Baptist by Giovanni di Turino; the Baptist Preaching by Giovanni di Turino; the Baptism of Christ by Ghiberti; the Arrest of John the Baptist by Ghiberti; the Feast of Herod by Donatello. These panels are flanked on the corners by six figures, two by Donatello (Faith and Hope); three by Giovanni di Turino (Justice, Charity and Providence), and the Fortitude by Goro di Ser Neroccio.

The marble shrine on the font, the five Prophets in the niches and the marble statuette of John the Baptist at the top were designed by Jacopo della Quercia.
