plebeian, laid claim to high antiquity, since a Petronius Sabinus is said to have lived in the reign of Tarquinius Superbus. [PETRONIUS, No. 1.] The coins struck by Petronius Turpilianus, who was one of the triumvirs of the mint in the reign of Augustus, likewise contain reference to the real or supposed Sabine origin of the gens.
