The Constant Prince

(El príncipe constante)

Pedro Calderón de la Barca

A Comedia histórica - wr. 1629

The Portuguese Army, led by Prince Ferdinand, engages the Moors in battle near Tangiers. The Portuguese are defeated, and Ferdinand is taken prisoner. The King of Fez demands the city of Ceuta as his ransom, but Ferdinand refuses to let a Christian city be given to the Moors. The King orders Ferdinand to be treated as a slave, forced to do manual work, and is starved. Eventually Alfonso, King of Portugal, comes with his army to free the Prince but is too late. Ferdinand has died, but his spirit leads the army. The King of Fez's daughter is captured and returned to the Moors in exchange for the body of Ferdinand.
