Saint Christopher is venerated by several Christian denominations as a martyr killed in the reign of the 3rd-century Roman emperor Decius (reigned 249–251) or alternatively under the emperor Maximinus Daia (reigned 308–313).
His most famous legend tells that he carried a child, who was unknown to him, across a river before the child revealed himself as Christ. Therefore, he is the patron saint of travellers, and small images of him are often worn around the neck, on a bracelet, carried in a pocket, or placed in vehicles by Christians.
