Saint Sebastian (in Latin: Sebastianus; Narbo, Gallia Narbonensis, Roman Empire c. AD 255 – Rome, Italia, Roman Empire 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 Saint 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 was clubbed to death. He is venerated in the Catholic Church and the Orthodox Church. The oldest record of the details of Sebastian's martyrdom is found in the Chronograph of 354, which mentions him as a martyr, venerated on January 20. He is also mentioned in a sermon on Psalm 118 by 4th-century bishop Ambrose of Milan (Saint Ambrose): 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. Saint Sebastian is a popular male saint, especially today among athletes. In medieval times, he was regarded as a saint with a special ability to intercede to protect from plague, and devotion to him greatly increased when plague was active. Early life The ancient source mentioning Sebastian is found in the Chronograph of 354, a compilation of chronological and calendrical texts produced in 354 AD by the calligrapher and illustrator Furius Dionysius Filocalus, which mentions him as a martyr who was venerated on January 20. His cult is also mentioned by Ambrose of Milan in his Expositio in Psalmum CXVIII, a theological and exegetical commentary of Psalm 118 dated to 386-390 AD; Ambrose states that Sebastian came from Milan and that he was venerated as a Saint there. The first surviving account of Sebastian's life and death is the Passio Sancti Sebastiani, long thought to have been written by Ambrose in the 4th century, but now regarded as a 5th-century account by an unknown author (possibly Arnobius the Younger). This includes the "two martyrdoms", and the care by Irene in between, and other details that remained part of the story. According to
