Abelard, Peter. [Letter to Heloise, abbess of the Paraclete, undated] in Peter Abelard’s Hymnarius Paraclitensis 2.9-13, 2.79-81, 2.169-70

[Letter from Peter Abelard to Heloise, abbess of the Paraclete]
Heloise asked Abelard for hymns and he addresses her in the prefaces to the three books of hymns he composed for her. He refers in the first preface to Heloise’s comments on the confusion among existing translations, the discrepancy between meter and music, and between subject matter and liturgical practice. The hymns themselves include examples of several forceful women, particularly the Virgin Mary.
