the daughter of a man of consular rank, was first the wife of Vitellius, and subsequently of Dolabella. On the accession of Vitellius to the empire, A. D. 69, her husband Dolabella was put to death by his orders. She had a son by Vitellius named Petronianus, who was blind of one eye, and whom his father put to death. (Tac. Hist. 2.64; Suet. Vilell. 6.) The Ser. Cornelius Dolabella Petronianus, who was consul A. D. 86, in the reign of Domitian, may likewise have been a son of Petronia by her second husband.
