Crispin
a Roman martyr of noble family. Obliged to flee from Rome during the persecutions of Diocletian, Crispin maintained himself in what is now Soissons, France, by making shoes. He was so charitable, the legend runs, that he even stole leather to make shoes for the poor. He suffered martyrdom in 287. October 25th is St. Crispin's day. He is the patron saint of shoemakers, who are jocularly called knights of St. Crispin.
