Biography of Valerius Magio
Inscriptions are almost entirely lacking in Künzing, but a small altar records an honourably discharged veteran ('missus honesta missione'), Valerius Magio, as a worshipper of the 'Undefeated Mithras' (Mithras Invictus).
Veterans, that is to say soldiers who had been discharged honourably with all attendant privileges and financial settlements, can occasionally be foud as dedicants in the record. Howsever, these instances mostly refer to legionary veterans and in few instances to alae or Roman city troop veterans. Ocasionally, as in Künzing, the honourable discharge – honesa missio – is mentioned, but that practice was widespread and not unique to this cult.
