CCCC MS 80 contains Henry Lovelich's English versions of The History of the Holy Grail and Merlin written c. 1450-75. The Corpus manuscript is the unique copy of these texts, translated and versified from the French prose version. Lovelich was a member of the Skinners' Company of London, and it seems likely that, until it came into Parker's possession, this manuscript had remained in or around London. Certainly it contains a number of notes added in the later fifteenth century in the hand of John Cok, a priest at the Augustinian hospital of St Bartholomew at Smithfield.
