A military diploma of 2 July a.d. 133 (RMD I, 35), first discovered in 1960 but published several times since, has provoked a debate concerning the origin of the discharged soldier, with commentators proposing either Corinium in Britain or the Cornacates in Lower Pannonia. The new reading presented here suggests that the soldier was actually Cornovian, allowing a reassessment of the recruitment of Brittones in the Roman auxilia.
