Flavius Antistianus

Flavius Antistianus was a Mithraic leader active in Rome, known from a dedication to Cautes discovered on the Capitoline Hill (TNMM 713). In the inscription he identifies himself as vir egregius de decem primis pater patrum, indicating both membership of the equestrian order and occupancy of the highest office attested within the Mithraic hierarchy.

The title vir egregius marks Antistianus as a man of elevated social standing, while the distinction de decem primissuggests inclusion within a select group of senior imperial officials. His inscription therefore provides valuable evidence for the participation of members of the Roman equestrian elite in the leadership of Mithraic communities.

The dedication was discovered near the Porta Arae Coeli on the Capitoline Hill and has sometimes been associated with the hypothetical Mithraeum of Lo Perso, although the existence and location of this sanctuary remain uncertain. Regardless of its precise archaeological context, the monument confirms the presence of a pater patrum of equestrian rank in Rome and illustrates the close relationship between social prestige and religious authority within Roman Mithraism.
