Pere Riu (O. Carm.), John of Aragon (1350-96), Psalm 50, Medieval Catalan.
This article studies, and offers and edition of, a hitherto unknown preface to friar Pere Riu’s short commentary on Psalm 50 (Barcelona, Biblioteca de Catalunya, MS 1031, fol. 9r-10r). Addressed to a certain “lord the Duke,” in all likelihood Crown Prince John of Aragon, and possibly dating to the 1370s, the theological contents of this prefatory text may shed new light on the education of John of Aragon.
