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 3 contains the lives compiled by William Fitzstephen and Herbert of Bosham, one of Becket's longest-serving clerks and probably his closest friend.
