The Caravaca Cross is named for a city in Spain where a miracle occured in the 13th century. While the city was controlled by the Moors it is said that the Muslim ruler asked a captured Catholic priest to demonstrate the conscretation of the eucharist. When the priest remarled that there was no cross present, one appeared in the window carried by a pair of angels. The muslim ruler was so amazed that he converted to Christianity.
