St. Dominic, Founder of the Dominicans (1170-1221), who established the devotion of the Rosary being handed to him by Jesus (garland of roses).
The Latin word for Dominican is dominicanis, meaning Dog of God. According to legend, St. Dominic's mother while pregnant dreamed that she would give birth to a dog who would hold a torch in its mouth and would "burn the world." A dog is often shown at the saint's feet holding a torch (knowledge) in its mouth.
