Galla was the daughter of Roman patrician Symmachus the Younger, who was appointed consul in 485. Galla was also the sister-in-law of Boethius. Her father, Symmachus the Younger, was condemned to death, unjustly, by Theodoric in 525. Galla was then married but was soon widowed, just over a year after marriage. It was believed that she grew a beard, to avoid further offers of marriage. Being wealthy, she decided to retreat to the Vatican Hill, and found a hospital and a convent, near St. Peter's Basilica. Galla is reputed to have once healed a deaf and mute girl, by blessing some water, and giving it to the girl to drink. Galla remained there for the rest of her life, tending to the sick and poor, before dying in 550, of breast cancer.
