Volume II of the AUTHORS OF THE MIDDLE AGES series contains nos. 5-6 in the series: 'Peter Abelard' by Constant J. Mews and 'Honorius Augustodunensis' by V.I.J. Flint. PETER ABELARD (1079-1142) was one of the most creative and controversial thinkers of the 12th century. This study traces his life as a logician and theologian, paying particular attention to the many scholarly debates provoked by the Historia calamitatum and the celebrated exchange of letters with Heloise. It contains a full survey of his writings, listing the manuscripts in which they occur. HONORIUS AUGUSTODUNENSIS, c. 1098-c. 1140, one of the most prolific and widely read authors of the early 12th century, was a passionate proselytiser on behalf of the Benedictines. This study sets out the extraordinary features of his career and the nature of the battle he fought through his writings. Few of his works have appeared in modern editions, this study gives short accounts of each and their manuscripts.
