 As noted, it is now generally assumed that Probus was the official referred to in that inscription, even though his name has disappeared from the text.Indeed, he may have been Numidia's first equestrian governor.Therefore, it is highly likely that Probus was an early beneficiary of Gallienus's policy of giving equestrians military commands (over legions) and administrative posts (as governors of propraetorial provinces) that, prior to Gallienus' sole reign (260-268 AD), had been reserved almost exclusively for men of senatorial status.
