An Inscription from Aquileia

[D B Campbell]

Servilianus is described as 'a militiis' - does this simply mean he was an equestrian officer?

a militiis seems to be a late-ish phrase (Severan+) to indicate that a man had completed his equestrian military service. As far as I can tell.

Does the last phrase mean something like 'commanders of the military forces in the protection of Aquileia'? Would this probably refer to the siege itself, or some more general activity?

I'd guess more generally. But the inscription is dated to AD 238 (the time of the siege). The milites who had been entrusted with the defence of Aquileia probably came from Adiutor's cohort. (I'd guess.)

Lastly, is it at all likely that the Flavius Salvianus named above is the same man who appears on this inscription from Mainz

Different name?
