Helena Augusta, mother of *Constantine I. Born of humble origins at Drepanum in Bithynia, she became c. ce 270 the first wife (or perhaps concubine) of the future emperor Constantius I. On Constantius’ later dynastic marriage to Theodora, Helena lapsed into obscurity, returning to prominence after her son's elevation as emperor in 306; she followed Constantine in adopting Christianity. In 324 she was given the title Augusta, and c.327 made a celebrated imperial progress through the eastern provinces as far as Jerusalem, where she engaged in charitable activities and was associated with the building of Constantine's new churches at the holy places. In Christian tradition her journey became a model of Holy Land pilgrimage, and by the later 4th cent. she was believed to have discovered relics of the True Cross.
