CIMRM Supplement - Mithraeum and fragments. Septeuil-Les Yvelines, France.
The Septeuil Mithraeum was discovered in 1984 at a shrine dedicated to a spring, and near a large temple dedicated to the waters of Apollo and the mother goddesses. The site is flooded, so difficult to interpret. The Mithraeum was created within a nymphaeum, by repurposing one of the existing chambers at a later date. The statue of the nymph was reused within the mithraeum. Around 1300 coins were also found, covering a period of only 70 years.
The relief fragments are on display in Musée d’Archéologie nationale.
