Pedro Calderon de la Barca (1600 - 1681).

Calderon was a Roman Catholic priest, writer, poet and dramatist of the Spanish Golden Age who succeeded Lope de Vega. He wrote a play about the Bastard Don John of Austria, whom Shakespeare introduced into the Messina of Much Ado About Nothing; and he also matched Shakespeare in writing a play about Henry VIII and Katherine of Aragon called La Cisma in Inghilterra (see "Shakespeare and the Spanish Connection" in the Video Anthology attached to this website).
