Arpineia gens
The gens Arpineia was an obscure plebeian family at ancient Rome. It is known chiefly from a single individual, Gaius Arpineius, an eques in the army of Caesar's army during the Gallic Wars. Origin. The nomen "Arpineius" belongs to a class of gentilicia formed using the suffix "-eius", typically formed from words or names ending in "-as". The root of the nomen is the cognomen "Arpinas", a surname indicating a relationship to the city of Arpinum in southern Latium, whence the ancestor of this family probably came.
