Saint Sebastian was a 3rd-century Christian martyr and is venerated as a saint in the Roman Catholic, Eastern Orthodox, and some Protestant traditions. Originally from Milan, he became a soldier in the Roman army, where he secretly converted many soldiers to Christianity. His faith was discovered, leading to his arrest under Emperor Diocletian's persecution.

Legend has it that Sebastian was tied to a tree and shot with arrows by his fellow soldiers but survived this ordeal. He was later healed by a Christian widow, Irene of Rome. Despite his miraculous recovery, he continued to speak out against pagan practices, which led to his being beaten to death by orders of the emperor.

Saint Sebastian’s story is often depicted in art, showing him bound to a tree and pierced by arrows. His feast day is celebrated on January 20. His enduring image symbolizes faith and resilience, and he is invoked as a patron saint for protection against plagues and diseases.
