Christian Saints

St. Roch was born in Montpellir, the son of a rich merchant. He became a hermit, and made numerous pilgrimages. Once he discovered that he was inflicted with plague. To avoid spreading infection, he hid himself in the woods and was fed by a dog, which stole him a loaf of bread a day from his master’s table. An angel cured him and he returned to Montpellir, where nobody recognized him. He was accused in espionage and thrown into prison, where he died. St. Roch is the patron saint of the plague-inflicted. Depicted in pilgrim’s clothes, sometimes with dog.
