Looking for a legionary

[Nathan Ross]

I wonder whether 'Arilius' might be a misprint of 'Aurelius'.

There's an Aurelius Genialis, duplicarius of Legio I Adiutrix, mentioned on a late Severan stone (AE 1909,146) from Brigetio. That's the only soldier by that name I can find. Perhaps Michael might have more luck?

There's also a Caius Atilius Genialis from Spain, but he doesn't seem to have been a soldier.
