In a painting by Lorenzo 
In a painting by Lorenzo Lotto, this figure appears between Saint Rocco and the arrow-pierced Saint Sebastian.  While in prison, he converted two women who were assigned to seduce hime, and when one of his tormentors tried to shoot him the arrow rebounded and struck his attacker in the eye.  After he performed his most famous act, he was told to plant his staff in the ground, and the next day it grew flowers.  Martyred in Lycia during the persecutions of Decius, after he was beheaded his huge body was dragged through the city where he had preached, though before becoming a preacher he worked carrying people across a river.  FTP, name this patron saint of travellers, who famously carried the Christ child across the river.
