A manuscript, apparently of St Davids provenance, which is now lost but receives a mention from John Leland in the 16th century. On the basis of this reference and others, it has been suggested that its contents included texts, or textual versions, of early charters associated with the house.
- s. ix / s. xii
A manuscript now lost but listed in the 12th-century library catalogue of Lincoln Cathedral, where the title has been crossed out. To judge by the title, it would appear to have contained a version of the Proverbia Grecorum.
A purely hypothetical ‘very ancient book in the British language’ (quendam Brittanici sermonis librum uetustissimum) containing a history of the deeds of the kings of Britain, from Brutus to Cadwalladr, which Geoffrey of Monmouth alleges to have rendered into Latin when writing his Historia regum Britanniae, a work known for its audacious originality. Geoffrey mentions it in the preface to this work, where he claims to have received the book from Walter, archdeacon of Oxford. Whatever his source material may have been, or Walter’s role in supplying it, the claim that so much of this was written in the vernacular and contained in a single volume (implicitly, to which few would have access) is commonly regarded as a spurious appeal to authority.
A manuscript listed as ‘Irishe physique’ in Robert Cotton's library catalogue of manuscripts (BL, Harleian 6018). Engl. physick referred to medicine, but in the retained French spelling physique it could mean ‘natural philosophy’. The manuscript has not been identified and may have been lost.
Hypothetical lost manuscript, perhaps a gospel-book, associated with the Céli Dé monastery of Loch Leven. An old volume of the Scots (veteris voluminis antiquo Scotorum idiomate conscripti) is cited in the St Andrews register as having served as the source for a series of Latin charter records for Loch Leven. The presence of such records added to the margins and available spaces in the Book of Kells and other gospel-books suggests that the Loch Leven manuscript, too, or its source, may have been a gospel-book.
