Cambridge University Library, Ff. i.27

Cambridge University Library, Ff. i.27 is a composite manuscript at the University of Cambridge. It was formed by adding a 14th-century Bury St Edmunds book to a compendium of material from 12th-century northern England (items 1 to 11 in the Contents).^[1] The latter compendium had once been part of Corpus Christi College Cambridge MS 66.^[2] With its original content, it had at one time been at Sawley Abbey in Lancashire, though it was probably produced somewhere else, perhaps Durham.^[3] It is a source for the Durham poem, which describes the city and its relics.^[4]

Ff. 1.27 as a whole came together in the 15th century or later, but pages 1 to 236 are earlier; and paleographic evidence suggests that, with the exception of a continuation of Gildas' De excidio Britanniae dating to the 14th century, its material shares the same origin.^[5] Ff. i 27 and Corpus Christi 66 manuscripts probably had a common origin with Corpus Christi College Cambridge MS. 139 ("CCCC 139") as well, part of Ff. 1.27 being written in the same hand as part of 139's version of the Historia Regum.^[6]
