Mithréum de Septeuil

In the second half of the 4th century, a Mithraic temple was established within an earlier spring sanctuary at Septeuil, where the cult of the nymphs and Mithraic practices appear to have coexisted.
Near the village of Septeuil, in the Yvelines department (Île-de-France), lie the very faint remains of a Mithraic sanctuary discovered in the 19th century. The site sits directly along the modern national road linking Mantes-la-Jolie to Houdan — an unexpected location for a mithraeum, usually associated with caves, secluded areas or buildings set apart from traffic.

Today almost nothing is preserved: a slight depression in the ground, a few displaced stones, and a modern marker indicating the approximate position of the shrine. This near-complete disappearance gives the place a strangely elusive character, as if the sanctuary had slowly been absorbed by the contemporary landscape.

The photographs show what can still be seen on site. Despite the minimal remains, the location retains a quiet atmosphere, suspended between the flow of present-day traffic and the memory of a mystery cult once practiced here.

Glad to be helpful. I can share two additional photographs of the site, showing the overall layout and its unusual position along the modern road. They don’t add archaeological detail, but they may help convey the atmosphere and the spatial context of the sanctuary as it appears today.Glad to be helpful.

Re-interpreting the Mysteries of Mithras

Ernest Renan suggested that without the rise of Christianity, we might all have embraced the cult of Mithras. Nevertheless, it has had a lasting influence on secret societies, religious movements and popular culture.

Column of Callimorphus

Callimorphus dedicated this image of the sun god to the invincible sun ’Mythra’.
I am researching the Latin inscription dedicated by Callimorphus to Mithras (EDCS-27800570 / CIL III 12135). Could you please let me know if you have any information about the current location or custody of this inscription?

Thank you very much for your help.

Best regards,

Dilara.
Hello

I am currenty conducting a research about the widespread of Mithraism in Asia Minor and its possible influence on the society.
Do you know if there are other evidence on Callimorphus or Chresimus? Maybe other inscriptions?

Thank you very much for the help

Sincerely
