Saint Helena († c. 330), was the consort of the future Roman Emperor Constantius Chlorus (reigned 293-306) and the mother of the Emperor Constantine the Great (reigned 306-337). She ranks as an important figure in the history of Christianity and of the world due to her significant influence on her son. Tradition credits her with a pilgrimage to Syria Palaestina, particularly to Jerusalem, during which she allegedly discovered the True Cross.
