Saint Christopher is a Christian martyr and is often recognized as the patron saint of travelers. According to legend, he was a giant who dedicated his life to helping people cross a dangerous river. One day, he carried a child across the water, who later revealed himself to be Jesus Christ. This act of service led to Christopher's conversion to Christianity. Saint Christopher is commonly depicted in art as a large man carrying the child on his shoulders. His feast day is celebrated on July 25, and many people wear Saint Christopher medals for protection during their travels.
