Drawing upon the research presented in Ewald Konsgen's 'Epistolae duorun amantium: Briefe Abaelards und Heloises? (Leiden: E.J. Brill, 1974), Mews offers a compelling thesis that letters discovered and transcribed in Clairvaux in the 15th century are the 'lost' love letters of Peter Abelard and Heloise. Mews asserts that the letters in question were written 'by two articulate individuals who lived in the Ile-de-France in first half of the 12th century [who] were fully conversant with the classical authors known at that time', a point made by Konsgen but further developed by Mews. Indeed, it is made clear that not only are the Clairvaux letters the work of two distinctly different authors, but that woman is the man's student, "the only disciple of philosophy among all the women of our age" as he calls her, the man a famous teacher, a master of philosophy and a poet. The author begins with the discovery of the letters in a monastery at Clairvaux and their transcription by the monk Johannes de Vespria. He then follows with a discussion of the 'known' (and still controversial) letters of Abelard and Heloise and how those letters shaped the subsequent perception of their relationship. Mews goes on to compare the vocabulary of the known letters with the Clairvaux letters, arguing that the parallels are so striking that it "stretches plausibility to argue that the letters were written by any one other than Abelard and Heloise." He finishes his analysis by showing the implications of this discovery to the present understanding of the evolution of their relationship. The final chapter is a transcription of the Clairvaux letters in Latin, with a parallel translation in English. Throughout the book, Mews throws light on the broader issues of communication between men and woman in 12th century France. He also places the 'story' of Abelard and Heloise into the broader context of their era, explaining how the political upheavals and cultural changes of the 12th century played a part in their relationship and in their lives in general. Mews' argument is reasoned, well researched, and entirely convincing. As for the letters themselves, erotic and sensual, they offers a tantilizing glimpse into the early relationship of Abelard and Heloise - but there are mysteries here too. What is the cause of the rift that seems to have happened between the writing of letters 57 and 58? What does the woman mean when she writes "If you are well and moving among wordly concerns without trouble, I am carried away by a great exultation of mind"? Is this truly Heloise writing to Abelard about the birth of their child? Both writers fill their letters with imagery about the stars, the sun and moon, and celestial light - is this what prompted Heloise and Abelard to name their child (Peter) Astrolabe? The real importance of these letters may be in their discussion of the true nature of friendship and love, which may shed light on and help us to better understand the 'known' letters of Abelard and Heloise. In the Clairvaux letters, the woman seems determined to define their relationship and convince the man of her true love for him; the man seems more preoccupied with the erotic nature of their friendship. These letters are also important in illustrating what a poetic and original writer Heloise was - an idea often overlooked by those more preoccupied by the romance and tragedy of her story. I look forward to reading more arguments concerning authorship of these lost letters, and I encourage not only scholars, but lay people like myself to read this book. ( )
