Saint Sebastian

Sebastian (Latin: Sebastianus; c. AD 255 – c. AD 288) was an early Christian saint and martyr. According to traditional belief, he was killed during the Diocletianic Persecution of Christians. He was initially tied to a post or tree and shot with arrows, though this did not kill him. He was, according to tradition, rescued and healed by Irene of Rome, which became a popular subject in 17th-century painting. In all versions of the story, shortly after his recovery he went to Diocletian to warn him about his sins, and as a result he was clubbed to death. He is venerated in the Catholic Church and the Eastern Orthodox Church as the patron saint of athletics, archery, and plagues.

The oldest mention of Sebastian's martyrdom is in the Chronograph of 354, which says he is venerated on January 20. He is also mentioned in a sermon on Psalm 118 by 4th-century bishop Ambrose of Milan: in his sermon, Ambrose stated that Sebastian came from Milan and that he was already venerated there at that time. The full account of his martyrdom comes from the Passio Sancti Sebastiani, a 5th-century text written by an anonymous author, possibly Arnobius the Younger.
