Siena Baptistery of San Giovanni

The Battistero di San Giovanni (Italian: "Baptistry of St. John") is a religious building in Siena, Italy.

In the interior, the rectangular hall, divided into a nave and two aisles by two columns, contains a hexagonal baptismal font in bronze, marble and vitreous enamel, realized in 1417-1431 by the main sculptors of the time: Donatello (panel of "Herod's Banquet" and statues of the "Faith" and "Hope"), Lorenzo Ghiberti, Giovanni di Turino, Goro di Neroccio and Jacopo della Quercia (statue of John the Baptist and other figures).

The panels represent the Life of John the Baptist, and include: These panels are flanked on the corners by six figures, two by Donatello ("Faith" and "Hope") in 1429; three by Giovanni di Turino ("Justice", "Charity" and "Providence", 1431); and the "Fortitude" is by Goro di Ser Neroccio (1431).

The five "Prophets" in the niches and the marble statuette of "John the Baptist" at the top are equally by his hand.

Two of the bronze angels are by Donatello, three by Giovanni di Turino (the sixth is by an unknown artist).
