Pedro Calderon de la Barca was born in Madrid, January 17, 1600, of good family. He was educated at the Jesuit College in Madrid and at the University of Salamanca; and a doubtful tradition says that he began to write plays at the age of thirteen. His literary activity was interrupted for ten years, 1625-1635, by military service in Italy and the Low Countries, and again for a year or more in Catalonia.
