Pinnes, whose full praenomen remains unknown, is recorded on a 2nd century AD altar from Grude, near Tihaljina in Bosnia and Herzegovina. As ’immunis miles’ in the Cohors I Belgarum, he was exempt from some standard military duties, possibly indicating a specialised role. Stationed in Dalmatia during the Antonine period, the Cohors I Belgarum mainly recruited ’peregrini’, non-citizens of Rome. Pinnes’ inscription, dedicated to Mithras, suggests his integration into the religious life of the Roman military. His name indicates a probable Dalmatian origin, reflecting the Roman army’s practice of recruiting from the local population.
This altar, discovered in Grude, near Tihaljina, Bosnia and Herzegovina, bears an inscription by Pinnes, a soldier of the Cohors Prima Belgica.
