Euphemia (; "well-spoken [of]"), known as the All-praised in the Eastern Orthodox Church, was a virgin, who was martyred for her faith at Chalcedon in 303 AD. According to tradition, Euphemia was arrested for refusing to offer sacrifices to Ares. After suffering various tortures, she died in the arena at Chalcedon from a wound sustained from a bear. Her tomb became a site of pilgrimages. She is commemorated on September 16. Historical background Euphemia's name and year of death are recorded in the 5th century Martyrologium Hieronymianum, the earliest extant list of Christian martyrs. The year, 303, was the first year of the Great Persecution under Roman emperor Diocletian. The Fasti vindobonenses, a collection of liturgical documents from the 4th to 6th centuries, says she died on the 16th of October. Other than this, there is no verifiable historical information about Euphemia. Egeria, who made a pilgrimage to the Holy Land about 381-384 and wrote an account of her travels, relates being shown the site of Euphemia's martyrdom in Chalcedon. Euphemia became a famous saint and stories about her accumulated; the Golden Legend, a collection of hagiographies from about 1260, includes an account of her martyrdom. Hagiography St. Euphemia lived on the cusp of the 3rd and 4th centuries AD. According to tradition, she was the daughter of a senator named Philophronos and his wife Theodosia in Chalcedon, located across the Bosporus from the city of Byzantium (modern-day Istanbul). From her youth she was consecrated to virginity. The governor of Chalcedon, Priscus, had made a decree that all of the inhabitants of the city take part in sacrifices to the deity Ares. Euphemia was discovered with forty-nine other Christians hiding in a house and worshipping God, in defiance of the governor's orders. Because of their refusal to sacrifice, they were tortured for a number of days, and then, all but Euphemia, sent to the Emperor for trial. Euphemia, the youngest among them, was separated from her companions and subjected to particularly harsh torments, including the wheel, in hopes of breaking her spirit. She was placed in the arena, where lions were sent out to kill her, but they instead licked her wounds. It is believed that she died of wounds from a wild bear in the arena.
