The son and one of the creators of the Spanish Golden Age , Calderon (16000 1681) was an inexhaustible playwright - he wrote more than 200 original comedies and autos sacramentales, dramatic works in which he gave artistic expression to seemingly abstract concepts of theology. A persistent labourer, Calderon continued reshaping and rewriting his own work, seeking esthetic perfection. Tightly knit, his plays are full of intricately organized action and nexpected, yet natural, motivations.
