Siena Cathedral: Baptistery Font: Overall view, set in a frescoed apse

The hexagonal basin bears six gilded bronze reliefs of the Life of St. John the Baptist, separated by six free-standing bronze Virtues set in shallow marble niches. The center panel is 'St. John the Baptist brought before Herod' , the panel to the right is 'The Feast of Herod.'\u000a\u000aIn the early 15th century a new type of font developed. This so-called Renaissance font is approached by a flight of steps, at the top of which is a polygonal, square or round basin, supported on a pedestal and covered by a lid. The side of the basin and the lid are usually ornamented. The most influential design in the type's development was the new font (1416-1431) for the Siena Baptistery, on which Lorenzo Ghiberti was commissioned to advise, with decoration by Ghiberti, Donatello, Jacopo della Quercia and others. This was innovative in its structure, with a lidless basin and a tabernacle, and in its combination of bronze and marble. The hexagonal basin bears six gilded bronze reliefs of the Life of St John the Baptist, separated by six free-standing bronze Virtues set in shallow marble niches. Gold and azure blue enamelled friezes and inscriptions decorate the rim of the basin and the steps. A cluster of columns in the middle of the basin supports the hexagonal marble tabernacle, which is fashioned after Florentine models. On five sides there is the figure of an Apostle, set within a niche, while on the sixth there is a small door, behind which are stored the baptismal ointments. Putti crown the corners of the tabernacle, and above these rise columns supporting a statue of St John the Baptist.
