Raised under Diocletian, certainly in connection with the creation of the new province of Pontus Polemoniacus in AD 297. The legion’s headquarters was at Trapezus, where the inscription CIL III.6746 “dedicavit leg(io) I P(ontica) vestra agent(e) Trocnudo pr(a)efaec(to)” was consecrated by Diocletian and his co-ruler after AD 293. The legion was still in this camp during the period of the Notitia Dignitatum Orientis XXXVIII v.16: “praefectus legionis primae Ponticae, Trapezunta”. It was then under the command of the dux Armeniae. Originally, the command structure in the North-East of Asia Minor was organized differently (see also 1351, 48).
