Juan Ruiz de Alarcón, a seventeenth-century writer and native of New Spain, so excelled at the craft of writing "comedias" that he is recognized as one of the great writers of early modern Spain. In his personal life Ruiz de Alarcón struggled with a significant bodily impairment, a large hump on both his back and front, which made him the target of much attention and scorn from his fellow writers and others in society. No journals or letters exist that document his personal life or attitudes toward his impairment. However, disability theory opens a way to explore the woven fabric of Ruiz de Alarcón's life and works. Both the themes and the characters in his popular comedias trace how his embodiment and experiences influenced his depiction of imperfections. Three of his seventeenth-century "comedias," "Las paredes oyen," "La prueba de las promesas," and "Examen de maridos," address different aspects of imperfection in both direct and indirect ways.
