Tauroctony from the Mithräum von Heddernheim

This relief is so well-known that it has been reproduced in nearly every handbook of archaeology and of history of religions.

As far as I can find the CIMRM number of this one is: 1083 and not 606.

Bronze medallion of Gordian III with tauroctony

The bronze medallion, from Cilicia, shows Mithras Tauroctonus on the revers.
Is the Date on the side correct? I guess it’s not 32 cm but 3,6 cm. Or am I wrong?
Indeed Yannick. The right size is 3.6 cm diameter. Thank you.

La grotta del Mitreo

The site was destroyed in the 5th century but some elements, including the benches, can still been seen.

This is actually in San Giovanni al Timavo, a little way along from Duino itself.

If you are in the area you can take a guided tour of the temple and it's surrounding area. This tour is described in detail on this page:

http://www.duinotourism.it/index.php?option=com_k2&view=item&id=1212:il-mitreo&Itemid=7&lang=en

There is also much more info here: http://www.gssg.it/index.php?module=subjects&func=printpage&pageid=28&scope=all (in italian)

According to wikipedia, mithraists always preferred natural caves to building things or expanding existing things so probably this area, known as the Carso, or Karst, is perfect for the original construction and long term preservation of this kind of temple in caves. They must have jumped for joy when they heard there was a mysterious river that popped out of the ground. I can't think of a better place for a mithra temple 🙂

The Rites of Hekate. From Dirt to the Divine

The Rites of Hekate is a personal yet deeply rooted academic account of the current understanding of this ambivalent goddess, presented as an arcane and liminal archetype.

Hekataion of Sidon

The Hekataion of Sidon, which depicts Hekate in her trimorphic form surrounded by three dancing girls, is the only example found to date in connection with the Mithraic cult.

He does indeed have a life jacket; it was mandatory for the Romans.

CIMRM 1017

A small limestone altar from Bandorf near Oberwinter dedicated to Deo Invicto Regi. Found in an isolated structure not resembling a mithraeum, its function remains uncertain.
Deo invicto regi; to God the invincible King. According to some relics, "lying down" means sea or river. Neptune or Oceanus. Both are archetypes of the Moon.

It’s like I’m being followed... but in a good way. ^__^
You’re doing a remarkable job (… and you’re the main reason I even venture onto fb 😉)
Honestly, thank you. Recognition helps.

🔥 UNDERGROUND RITUALS AND CANDLES – LIGHT IN THE DARKNESS 🕯️

Mithraea were not magnificent temples on hilltops. They were hidden underground — dark, elongated spaces with an altar at the end, symbolising the cave of the cosmos.

In such a place, light acquired a special meaning.

Worship took place by:

🕯️ the light of torches and oil lamps,
🍷 symbolic ritual meals,
🤝 oaths of loyalty among members of the brotherhood.

Mithraism was not a religion of the masses. It was a path of initiation, discipline, and quiet devotion.

For this reason it was especially popular among Roman soldiers — it taught brotherhood, trust, loyalty, and respect for order.

In the darkness of the mithraeum a light burned — not only a flame, but the idea that order overcomes chaos.

🏛️ In Poetovio too, a mithraeum once bore witness to these mysterious rites. In the very place where we walk today, torches once burned and oaths resounded.

Here, does the bas-relief come from Ptuj, or from Frankfurt-Heddernheim?
