The young boy in Francisco de Zurbarán’s (1598-1664) Saint Peter Nolasco Recovering the Image of the Virgin of El Puig (1630) has been suggested to be either Zurbarán’s son, Juan de Zurbarán (1620–1649), or the son of James I of Aragon, Alfonso of Castile (1229–1260). Despite visual dominance, most scholars do not address the boy, and those who do offer conflicting identifications. This paper bridges the gap between these varying opinions, and concretely identifies the most formally important figure in this commission that defined Zurbarán’s career. The argument is built on the writings of Zurbarán scholar Martin S. Soria, as well as a comparison to Zurbarán’s body of work at large, primarily his tendency to create from life, and his suspected self-portrait, The Crucified Christ with a Painter (1650). I conclude that the child in the piece is likely a culmination of Juan and Alfonso and explore the implication of Zurbarán depicting his child in the noble and pious role of James the Conqueror’s son, paying witness to the rediscovery of the Virgin of El Puig. The combined figure of Juan and Alfonso gains significance through an exploration of historical context surrounding the legend of the Virgin of El Puig and its key figures. By drawing parallels between 17th-century Spanish colonialism contemporary to Zurbarán’s time and 13th-century Reconquista depicted in the painting, Zurbarán uses this composite figure to assert a vision of his lineage as triumphant and divinely favoured. Ultimately, this paper continues and expands upon Soria’s writings on the subject, and places Zurbarán within a Baroque tradition of artists, such as Velázquez, who used painting to assert their profession as divinely-inspired, nobel, and distinct from craftsmen.
