Flavia Julia Helena Augusta (also known as Saint Helena and Helena of Constantinople, /ˈhɛlənə/; Greek: Ἑλένη, Helénē; c. AD 246/248– c. 330) was an Augusta and Empress of the Roman Empire and mother of Emperor Constantine the Great. She was born in the lower classes traditionally in the Greek city of Drepanon, Bithynia, in Asia Minor, which was renamed Helenopolis in her honor, though several locations have been proposed for her birthplace and origin.
