same man, that the first inscription provides the proper order he held those two provinces, and that he was governor in Britain before it was divided into two provinces (which happened by 217), he must have been governor of Britain during the sole reign of Caracalla. But if the order of the two provinces are reversed -- he was governor of Britain then Hispania Tarraconensis -- as Géza Alföldy argues, he was governor of Britain between 207 and 211, then governor in Spain c. 211–214. Or, if he was governor after Britain was divided into two provinces, he might have been the first consular governor of Britannia Superior. Lastly, if his career properly belongs to the later reigns of Valerian and Gallienus, then he could have been governor of either British province in the mid- to late 250s.
