The Comedia de Sepulveda survives in various 19th-century copies based on a lost 16th-century manuscript version. This edition reconstructs the original text, and argues for a date of composition of around 1565. The work consists of a series of variations on the theme of love and has strong parallels with Il Viluppo. The editor studies the relationship of the play to its source, its dramatic structure and the circumstances of performance.
