Grau [Delgado], Jacinto
(1877 - 1958) Spanish playwright. In reaction to the synthetic and trite nature of much Spanish theatre, Grau undertook to create an oeuvre of plays that explored serious themes, whether by farce or straight tragedy. Among his best - known plays are El hijo prodigo (1918), a thoughtful treatment of the story of the Prodigal Son; two plays dealing with the theme of an aging Don Juan, Don Juan de Carillana (1913) and El burlador que no se burla (1930); and El senor de Pigmalion (1923), a serious " tragi - comic farce " in which life - like puppets reveal the egocentrism and fallibility of human nature.
