The calling of the apostles St. Peter and St. Andrew

According to tradition, St. Andrew was crucified on an X-shaped cross, known as a Saint Andrew's Cross. This distinctive form of crucifixion is said to have been chosen as a reflection of St. Andrew's humility, as he felt unworthy to be crucified in the same manner as Jesus Christ. The image of St. Andrew holding the X-shaped cross has been a popular subject in Christian art and is a symbol of the saint's martyrdom. St. Andrew is the patron saint of Scotland and is revered by the Roman Catholic, Orthodox, and Anglican Churches.
