Alonso de Castillo Solórzano, prolific cultivator of the novelistic genre, gathered and published his work in miscellaneous volumes or colectáneas all along the XVII century. In these volumes, mainly formed by novels assembled in a narrative framework, dramatic pieces appear from time to time. This is the case of Fiestas del Jardín (1634), which alternates four plays written in prose and three comedies. We know about the last ones that they were brought to the stage by renowned authors of the time. However, the date of their composition remains unknown as well as the circumstances in which they were staged. It is our goal to shed light on these questions following the study of La fantasma de Valencia, one of the three aforementioned comedies.
