Peter Abelard's Letter to a Friend, frequently known as "The Story of My Calamities," recounts the meteoric and disastrous career of one of the driving forces of the twelfth-century renaissance. The son of a minor Breton noble family, a public intellectual who turned the academic establishment on its head, lover of Heloise, and sometimes his own worst enemy, Abelard produced in elegant prose one of the signal works of medieval autobiography. This new edition presents the Latin text as it appears in the earliest manuscript--until recently misdated by a hundred years--studded with a commentary that explicates the circumstances of its composition, context, and language.
