Contrary to popular belief, Pedro Calder?n de la Barca had a sense of humour. This book examines the integral and often essential use of humour in his works, looking beyond his persistent reputation as a dour and dogmatic representative of the Spanish canon. Calder?n's teatro breve (featuring mojigangas, entremeses and j?caras) thrives on comic techniques and situations that poke fun at everything and everybody, from aspiring nobility to people facing execution; and he parodies and satirizes genres and themes such as the auto sacramental or the infamous 'honour code'. His irreverence and desire for the audience's laughter are not just expressed in his teatro breve: the very same humorous techniques and situations, and even entire small works themselves, are found in his comedias, blurring and often eliminating the distinction between 'major' and 'minor' genres. Calder?n proves that the 'complementary' teatro breve need not live a separate existence, and that its presence within the comedia itself offers untold opportunities for novelty, diversion and criticism. By turning jokes into a dramatic art form and vice versa, Calder?n has much to teach us about the presence, role and functioning of humour in all of Spanish Golden Age theatre. TED L.L.
