Marcus Petronius Sura Mamertinus

Marcus Petronius Sura Mamertinus (died between 190-192 AD) was a Roman consul who lived in the 2nd century and was one of the sons-in-law of the Emperor Marcus Aurelius.

Mamertinus came from a wealthy, well-connected family of African origin—possibly from Egypt. His father, Marcus Petronius Mamertinus, was suffect consul in 150 and his mother's name is unknown. He had a brother, Marcus Petronius Sura Septimianus, who served as consul in 190, and a sister whose husband was the illustrious senator Marcus Antoninus Antius Lupus. Mamertinus was a kinsman of the grammarian Marcus Cornelius Fronto.

During the reign of Marcus Aurelius (161-180) and Faustina the Younger (161-175), Mamertinus married their daughter Annia Cornificia Faustina Minor in Rome.

Sometime after 173, Cornificia Faustina bore Mamertinus a son, Petronius Antoninus.

Mamertinus and his family could have been at the winter camp of Marcus Aurelius in early 180. When Marcus Aurelius died later that year, Mamertinus' brother-in-law Commodus succeeded him as Emperor. In 182, Mamertinus served as consul. Sometime between 190-192, Commodus ordered the deaths of Mamertinus, his son, his brother and his sister’s family. Cornificia Faustina survived the political persecutions of her brother and later remarried.
