Rais, also known as Iraida, Irais, Herais or Rhais, is a martyr venerated by the Roman Catholic and the Eastern Orthodox churches. According to one account, she was the daughter of a Christian priest living in Alexandria, Egypt. At age twelve, she was sent to live in a women's monastery at Tamman. One day in 303 AD, during a time of widespread persecution of Christians during the reign of the Roman emperor Diocletian, she went to a well to draw water with other nuns.
