About Temple of Jupiter
A Roman temple to Jupiter, now the cathedral's baptistery, its coffered stone ceiling is one of antiquity's finest, and a headless Egyptian sphinx still guards the door.
The Temple of Jupiter is a well-preserved Roman temple within Diocletian's Palace, built in the late third or early fourth century AD down a narrow lane just west of the Peristyle, facing the mausoleum. It was dedicated to Jupiter, the god whose name Diocletian carried in his imperial title Jovius. In the early Middle Ages it was converted into the cathedral's baptistery, the Baptistery of Saint John the Baptist, and it remains in religious use. Its barrel vault carries a richly carved coffered stone ceiling, one of the best-preserved of its kind from Roman antiquity.
A headless black granite Egyptian sphinx, another of Diocletian's imports, guards the doorway. Inside stands an eleventh-century cruciform baptismal font assembled from carved pre-Romanesque stone panels; one bears a relief of an enthroned ruler, traditionally identified as a medieval Croatian king and cited among the earliest stone depictions of a European sovereign, though the identification is debated. A bronze statue of Saint John the Baptist by the sculptor Ivan Meštrović also stands within.
Did you know? The temple's barrel-vaulted ceiling is carved into deep stone coffers and counts among the best-preserved Roman ceilings anywhere, it has hung essentially intact above the room since roughly 300 AD.
