‘In short, his edition is easily the most thorough to date in terms of its coverage and analysis of the internal features of the poem. Inevitably, now that the identity of the transcriber has been identified, Griffith covers the lost manuscript and its eighteenth-century transcript with greater detail and accuracy. And compared to Scragg and his predecessors, Griffith offers a precise and much lengthier exploration of the language and dialect of the poem, as well as its patterns of alliteration and metre in which, it should be said, Griffith is an acknowledged expert.’ Mark Atherton, Journal of Inklings Studies
