Margaret, known as Margaret of Antioch in the West, and as (, Hagía Marína) in the East, is celebrated as a saint by the Roman Catholic and Anglican Churches on July 20 and on July 17 in the Orthodox Church. Her historical existence has been questioned. She was declared apocryphal by Pope Gelasius I in 494, but devotion to her revived in the West with the Crusades. She was reputed to have promised very powerful indulgences to those who wrote or read her life, or invoked her intercessions; these no doubt helped the spread of her cultus.
