Battistero di San Giovanni in Fonte

The Baptistery of San Giovanni in Fonte survives beside Santa Restituta within Naples Cathedral. Its ancient basin and early Christian mosaics preserve a religious space established long before the Gothic cathedral around it.

Why it matters

The foundation is associated with Bishop Severo at the end of the fourth or beginning of the fifth century. The surviving decoration is an important witness to the visual language and baptismal traditions of early Christian Naples.

What to notice

Mosaics remain across the dome and its surrounding compartments. Scenes associated with Christ's ministry include the Wedding at Cana, the Samaritan woman and the Traditio Legis, in which Christ hands on the law. Richly coloured grounds and symbolic imagery connect narrative with the chamber's liturgical purpose. The sunken basin at the centre has a cocciopesto lining, a durable mortar used in ancient water structures.

Context and history

The baptistery belonged to the early cathedral complex associated with Santa Restituta. Medieval rebuilding incorporated these older spaces into the Angevin cathedral. Later repairs and losses changed the decorative ensemble, leaving fragments of an extensive mosaic programme rather than an entirely untouched early Christian room.
