of Materninius Faustinus
Materninius Faustinus built on his property one of the last known to date. He also ordered the construction of several of the monuments that decorated his temple, including the main tauroctonic relief. In two of the inscriptions found, Materninius is mentioned as Carax (Corax), i.e. the first grade of the Mithraic scale. The sanctuary, called fanum, was consecrated by a Pater by the name of Potentianus.

On 23 January 325 AD, Materninius Faustinus, an initiate of the first grade, that of Corax, in the Mithraic cult, had a temple of Mithras built in the town of Gimmeldingen, Germany. His dedication is engraved on the base of the cult relief of the temple. He also erected two altars and possibly a third with a similar inscription. Remarkably, Faustinus’ dedication is one of the last epigraphic testimonies of the Mithraic cult in the north-western provinces of the Roman Empire.
Its fervour was all the more remarkable given that the religious landscape of the Empire was in a state of flux: the Mithraeum was built just four months after the accession of Constantine I, who was perhaps already sympathetic to Christianity. Although there are later inscriptions dedicated to Mithras in regions such as Numidia and perhaps Phoenicia, the Faustinus dedication provides an invaluable insight into the continuing appeal of the Mithraic mysteries in the face of a burgeoning Christian empire in the former Gimmeldingen and the wider Rhineland.
Corax Materninius Faustinus dedicated other monuments found in the same Mithraeum in Gimmeldingen.
This sandstone altar was dedicated to the god Invictus by a certain Faustinus from Gimmeldingen.
The inscription was located at the base of the main Tauroctony of the Gimmeldingen Mithraeum.
