Saint Longinus is a figure in Christian tradition, often identified as the Roman centurion who pierced the side of Jesus during the Crucifixion. According to various accounts, he later converted to Christianity, moved by the events surrounding Jesus' death. Greek sources assert that he suffered martyrdom in Cappadocia after he changed faith. Longinus, who was said to have had poor eyesight, was healed when blood and water flowed from Jesus' side and splashed into his eyes.
