Soldier, bishop, saint. A career path which sounds a bit unusual. Martin was already a young soldier and only a catechumen when fully dressed in his military garb and on horseback, he happened upon cold and nearly naked beggar. His swift decision to split his cloak in half and give the beggar some warmth came back to him in his dreams later that night, when he saw a vision that Jesus himself was wearing the piece of the mantle Martin had given to the beggar.
This act of generosity has been reproduced hundreds of times and is no doubt the single most recognized event in long life of St. Martin of Tours.
Two paintings at the National Gallery in Washington, D.C. depict his youthful spontaneous generosity.
