13. M.Oppius, was proscribed together with his father in B. C. 43. The father was unable to leave the city of his own accord on account of his great feebleness through old age, but his son carried him on his shoulders and reached Sicily with him in safety. This instance of filial piety excited such admiration among the people, that he was afterwards elected aedile; and as he had not sufficient property to discharge the duties of the office, the people contributed the requisite money for the purpose, and on his death further testified their affection towards him by burying him in the Campus Martius. (Appian, App. BC 4.41; D. C. 48.53.) He is often said to be the same as the M. Oppius, whom Cicero calls in a letter to Pompeius (ad Att. 8.11, B) "vigilans homo et industrius," but the modern editions have M. Eppius and not M. Oppius.
