About Arria Galla

Atria Galla was a woman of ancient Rome related to various imperial intrigues by her husband, and reputed as "beautiful but low-born". She was first the wife of Domitius Silus but eventually left him for his friend Gaius Calpurnius Piso, whom she later became the second wife of. She may have been the mother of Piso's son, Calpurnius Piso Galerianus, though he also may have been adopted.
