On May 5 the Greek Orthodox Church commemorates the Feast Day of Agia Eirini, the Great Martyr.
Saint Irene was the daughter of a princelet called Licinius; named Penelope by her parents, through a divine revelation she was brought to faith in Christ and at Baptism was renamed, Irene.
In her zeal for piety, she broke in pieces all her father's idols, who commanded that she be trampled underfoot by horses. But while she remained unharmed, one of the horses rose up and cast down her father, killing him. She raised him to life again by her prayer, and he believed and was baptized.
Afterwards, in many journeyings, Saint Irene suffered torments and punishments for her faith but was preserved by the power of God, while working dread miracles and converting many thousands of souls.
At last, she came to Ephesus, where she fell asleep in peace, in the first half of the fourth century. Two days after her death, her gravestone was found lifted off, and her grave empty.
At least two churches were dedicated to Saint Irene in Constantinople, and she is also the patroness of the Aegean island of Thera, which is commonly called Santorin (or Santorini), a corruption of "Saint Irene."
