Mithraeum of Circus Maximus - Underground Rome
A large structure of the second century was discovered in good state of conservation and with a special and accurate decoration in marble. This structure changed several times and turned into a Mithraeum during the third century. The Mythraeum is a place used during the rituals of the mystery god Mithra.
During ancient times, the current entrance was the secondary one, while the main one was in correspondence of Circus Maximus. The first room on the right was intended to be an apparitorium, a sort of sacristy, while the second room appears to be a typical element of the Mithraeum: the pulpit, made of masonry, where the initiates sat during the functions and the ceremony of the sacred banquet. This sort of counter reappears in the last and most important compartment, the sacred place itself, the spelaeum, the cave in which the meeting with the god happened, through various degrees of purification.
