Saint Sebastian 

Saint Sebastian (c. AD 256 – 288) was an early Christian saint and martyr. According to traditional belief, he was killed during the Roman emperor Diocletian's 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 Roman Catholic Church and the Orthodox Church.
The details of Saint Sebastian's martyrdom were first spoken of by 4th-century bishop Ambrose of Milan (Saint Ambrose), in his sermon on Psalm 118. Ambrose stated that Sebastian came from Milan and that he was already venerated there at that time. Saint Sebastian is a popular male saint, especially today among athletes. In historical 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.
