Materials for the History of Thomas Becket, Archbishop of Canterbury (Canonized by Pope Alexander III, AD 1173)

This seven-volume work, published 1875-85, brings together all Latin materials concerning the life and fall of Thomas Becket (c.1120-70). Volume 4 contains two contemporary anonymous lives, one of which is tentatively ascribed to Roger of Pontigny, and the Quadrilogus, drawn from the narratives of four biographers.
