Helena, mother of Constantine I

Flavia Julia Helena (Ancient Greek: Ἑλένη, romanized: Helénē; AD c. c. 250 – c. 329), or Saint Helena was Constantine the Great's mother and a Roman empress (Latin: augusta). Helena was a wife or concubine of Constantius I before he became a Roman emperor.[1] In Christianity, Helena is a saint because Christian historians during Late Antiquity wrote that she found the relics of the True Cross in Jerusalem. Helena's tomb was the Mausoleum of Helena outside Rome.
