Half-sister of Constantine the Great
Half-sister of Constantine the Great and wife of Bassianus. She must have still been alive during the founding of Constantinople; the Thermae Anastasianae are named after her (Amm. Marc. 26,6,14). From time to time, her name, which refers to belief in the Resurrection, was regarded as circumstantial evidence of the fundamentally Christian convictions of her father Constantius (PLRE 1, 58, A.1).
