Personal and political networks connecting the descendants of Pedro I of Castile and those of Petrista loyalists reemerged in Castile at the turn of the fifteenth century, as a consequence of the marriage of Pedro's granddaughter, Catalina of Lancaster, to Enrique III. This article considers two inserted tales in Gutierre Díaz de Games' El Victorial as attempts to negotiate the integration of Petrismo into Castilian courtly culture. Both tales ("Cuento de los reyes" and "Cuento de Bruto y Dorotea") reveal an association between Petrismo, Troy, and Galicia that took shape in the years following the deposition and death of Pedro I and became an integral part of Petrista cultural memory. These connections are important not only for El Victorial, but also for the (as yet unwritten) cultural history of Petrismo, as well as for the history of Trojan matter in medieval Castile.
