Baths of Mithras Mithraeum

This is a passageway that leads down into the Mithraeum of the Baths of Mithras.

The Mithraeum of the Baths of Mithras was constructed in Regio I, Insula XVII at Ostia, in a service area of the baths.  It is 50 feet long and 15 feet wide.  The maximum height of the vault is about 6.9 feet high. There are two square skylights, one at the south end where a large statue of Mithras killing the bull was found.  It was probably constructed in the third century AD.

It was built to recall the cave in which the deity Mithras killed the sacred bull, releasing the secret of eternal life.
