Galla Placidia is one of the most interesting figures of the late Roman history. Daughter of Theodosius I and his second wife Galla, she grew up in the house of Stilicho and following his death she was captured by the invading Goths of Alaric. Alaric's successor Ataulf married Galla while being allied with her brother Honorius. After the Visigothic throne was usurped, she was passed to her brother and then married Constantius III. The future emperor Valentinian III was born, and Galla's influence steadily increased over the years, until Aetius became Magister Militum in 433. She remained a regent until 437 and died in 450. She is also known for the famous mausoleum in Ravenna, a perfectly preserved small chapel housing magnificent mosaics and three sarcophagi said to belong to her, Constantius III and Valentinian III.
