Saint Sylvia of Aquitaine was a fourth century pilgrim from Aquitaine. She was the sister of Rufinus, the prime minister of the Eastern Empire under Theodosius and Arcadius. Palladius' Lausiac History tells she journeyed in the age of 60, and prided in her ascetic habits.
In the late 19th century she was thought the author of a detailed pilgrimage account, but it is now attributed to Egeria.
