Marcus Valerius Maximianus

Marcus Valerius Maximianus was a senator, imperial legate and military commander from Poetovio in Pannonia Superior. After an exceptional equestrian career, he entered the senatorial order and served as legatus Augusti pro praetore, commanding Legio III Augusta in Numidia between AD 183 and 185. His career is known from several inscriptions, including the important dossier from Diana Veteranorum, Cuicul, Lambaesis and other African sites (Le Glay 1954; CIL VIII 4600; CIL VIII 8313; AE 1914, 25).

Maximianus is one of the most prominent high-ranking officials securely associated with the cult of Mithras. He dedicated monuments to Mithras both at Apulum in Dacia, where he served as legatus legionis of Legio XIII Gemina, and later at Lambaesis in Numidia, during his African command (TNMM 2029; CIMRM 138B; CIL III 1122; Le Glay 1954; Szabó 2018; Chalupa 2023). These dedications suggest a sustained personal devotion to Mithras rather than an isolated act of public piety.

His origin in Poetovio is significant, since the city was one of the important Mithraic centres of the Danubian provinces. Le Glay argued that Maximianus probably brought his devotion to Mithras from the Danubian world to North Africa, where the cult appears at Lambaesis under Commodus, in close connection with the military and administrative environment of Legio III Augusta (Le Glay 1954). This interpretation remains plausible, although it should be understood as a historical hypothesis rather than as a demonstrable fact.

Szabó has interpreted Maximianus as an example of the role of elite mobility, military networks and personal religious agency in the local spread of Mithraic worship. In this view, his dedications at Apulum and Lambaesis did not merely reflect private belief, but also helped to shape religious communities in places where he held authority. His case is especially important because, as a senator and Mithras worshipper, he seems to have interacted with religious groups that included soldiers and civilians of much lower social status, making him an unusually visible member of the senatorial elite within a Mithraic context (Szabó 2018).

No Mithraic grade is recorded for Maximianus. His senior social and political status may suggest an influential position within the communities he supported, but the evidence does not allow us to identify him as pater or as holder of any specific grade. His importance lies instead in the exceptional combination of senatorial rank, military command, provincial government and repeated Mithraic dedications across different provinces.
