Biography 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.
