This doctoral dissertation examines the manifestation of Christian reconciliation in three thirteenth century literary works from the Iberian Peninsula and the island of Mallorca, then part of the Crown of Aragon. This study discusses interpretations of the term “reconciliation” and applies the term to each work with regard to three aspects: reconciliation of self with self, of self with society, and of self with the divine. Chapter 1 discusses the various connotations of the term “reconciliation.” It outlines reconciliation as a synonym of penance, as in the four-steps in the Catholic Sacrament of Penance, now referred to as the Sacrament of Reconciliation. It also discusses the related Pauline concept of reconciliation and Paul’s possible sources. Chapter 2 will analyze these three aspects of reconciliation in an anonymous thirteenth century Castilian work in verse: La Vida de Santa María Egipciaca, or the Life of Santa María, the Egyptian. The prepubescent Alexandrian prostitute has an epiphany outside a church in Jerusalem, realizes the error of her ways, repents at the moment of intersection between human activity and divine intervention, and changes how she views herself, interacts with society, and regards the connection between earthly life and divinity. Chapter 3 takes a look at Gonzalo de Berceo’s cuaderna vía poem, written in Castilian about 1250 , Vida de Santa Oria, the Life of Saint Oria, through the same three lenses of reconciliation. This time the female figure is the Egyptian’s polar opposite. Oria is a young anchoress who has behaved in a saintly way mortifying the flesh since childhood. It might seem that in her case there is no need of reconciliation with herself because her virtue exceeds that of the majority of humans around her. I posit that, even in her case, there is room for acceptance of inner conflict. In addition, Oria reconciles herself to society (which admires her but tries to pull her back toward Earth against her will) and to the divine (which promises she will receive what she most desires when God deems it time). Chapter 4 studies the Romanç d’Evast e Blaquerna, a prose work in Catalan which dates from 1283-85. This early text provides an opportunity to analyze not only the protagonist’s reconciliation with self, society, and the divine but also that of an array of fictional characters including family members, his potential fiancée and the many people he meets along his journey to become a hermit. Finally, the Epilogue suggests that the idealistic notion of reconciliation has already been put to practical use in modern times in large-scale conflicts within and across borders. Coming to terms and living peaceably with differences, even grave ones, was accomplished at moments in Medieval Iberia among the three monotheistic religions: Christianity, Judaism, and Islam, and hope remains that such moments of peace will extend beyond borders and be found again today. / Spanish
