"...This chapter concludes Delbrugge's very informative, well-written, and focused introductory study... Her edition preserves most of the characteristics of the original; she has only added capitalization and punctuation when needed, and expanded abbreviations, but, for instance, she has not added accents. She has glossed it with helpful notes that guide the reader though the text, which is itself provided only in Castilian...In conclusion, Delbrugge's contribution is most welcome and relevant. Devotional literature was very important in the Late Middle Ages and the Renaissance, but very few works are available as scholarly editions--most have not even been published since the sixteenth century. This work is not only going to expand the body of Castilian religious texts available for specialists working on Iberian Studies, but also for those scholars working on religious literature and conversion--if, of course, they have the skills to read a text in fifteenth-century Spanish."Núria Silleras-Fernández, The Medieval Review, 12.06.32
