Late Roman Army Questions

[Nathan Ross]

their Roman names are probably good indicators that they and their families had become assimilated to Roman cultural norms.

Yes. Bonitus's father was presumably one of the various Frankish chiefs allied to Rome, and so gave his son a 'Roman' name as a mark of admiration for Roman ways (as with the Alemannic 'Serapio', who fought against Julian at Strasbourg). Unless, of course, Bonitus adopted a new name when he took up Roman military service. Since he was a prominent soldier in AD316-324, he would probably have been born in the closing decades of the 3rd century; so this sort of exchange goes further back than the 4th century.

Either way, it's a good illustration of the cultural permeability of the Roman/Germanic frontier at this point.
