Some modern scholars question parts of the story of Coriolanus. It is notable that accounts of Coriolanus' life are first found in works from the third century BC, some two hundred years after Coriolanus' life, and there are few authoritative historical records prior to the Gallic sack of Rome in 390 BC. Whether or not Coriolanus himself is a historical figure, the saga preserves a genuine popular memory of the dark, unhappy decades of the early 5th century BC when the Volscians overran Latium and threatened the very existence of Rome.
