Plans of the Mithraeum.
The Mithraeum is a barrel-vaulted room, like that at Santa Maria Capua Vetere.
The site was discovered in 1936 and consists of a room, 11.85 x 6.25 m, with a barrel vault and side benches. It has a complex fresco decoration. At the top is the sky, with the zodiac. Around it are ten boxes (pinakes) which tell the sacred story of Mithras. Also the personifications of Sol and Luna. The focus is on the central scene of the tauroctony where Mithras, flanked as usual by Cautes and Cautopates, ritually kills the bull.
The monument is currently (2014) under restoration.
