This e-book retells three works of Pedro Calderón de la Barca, a Spanish dramatist who lived in the seventeenth century: Life Is a Dream, The Purgatory of Saint Patrick, and The Wonder-Working magician. The first tells of a king who imprisons his son because of a disturbing astrological prediction and by his action brings upon himself the very doom that he sought to avert. The second tells of a cave in which all who enter experience all kinds of horrors, and only faith in Jesus can save them. The third tells of a demon who tries to obtain the soul of Cyprian by pretending to be a wonder-working magician, but fails.
