This volume provides detailed descriptions of Middle English prose materials found in the important manuscript collections of seven Cambridge Colleges: Christ's, Emmanuel, Jesus, Selwyn and Sidney Sussex Colleges, Peterhouse and Trinity Hall. The texts fall roughly into two categories: religious and devotional, or scientific. The former include Wycliffite New Testaments; Emmanuel College's complete Wycliffite Bible; Richard Rolle's Commentary on the Psalms in Sidney Sussex College, and, in Trinity Hall, the Twelve Conclusions of the Lollards in a splendid manuscript designed for presentation to Richard II. In the second category, there are several of outstanding interest: Jesus College Q.G.23 is a beautifully decorated English translation of the Chirurgie of Guy de Chauliac, while Peterhouse MS 75 is the sole manuscript of The Equatorie of the Planetis. As with all previous volumes in the series, this Handlist concludes with an alphabetical index of Incipits and Explicits intended to form part of an eventual Index of Middle English Prose. Angela M. Lucas is a Senior Member of Wolfson College, Cambridge.
