of Secundinius Amantius

TNMP 146
Secundinius Amantius was a cornicularius attached to the office of the prefect of Legio XXII Primigenia at Mogontiacum (Mainz). He is known from a marble altar dedicated jointly to Mithras and Mars, erected ex voto with the permission of Primulus, pater of the local Mithraic community (TNMM 513; AE 1979, 425; Herz 1978; Clauss 1992; Bricault and Roy 2021).
As a cornicularius, Amantius was a principalis, a military administrator serving in the officium of the legionary prefect. Clauss (1992) accordingly identifies him as a cornicularius from the office of the praefectus legionis of the legion stationed at Mogontiacum.
The dedication to Mars may indicate that Amantius held the Mithraic grade of Miles, for which Mars is traditionally regarded as the tutelary deity, although the inscription itself does not explicitly give him this grade. The dedication was made permittente Primulo patre, “with the permission of Primulus the pater”, providing evidence for both men belonging to the same Mithraic community.
