R. R. Tolkien and his legendarium. Llyfrawr. pp. 176 and 177. ISBN 978-1-4116-9370-8. "The 1849 translation of The Red Book of Hergest by Lady Charlotte Guest (1812-1895), which is more widely known as The Mabinogion, is likewise of undoubted authenticity ... It is now housed in the library at Jesus College, Oxford. Tolkien's well-known love of Welsh suggests that he would have likewise been well-acquainted with the source of Lady Guest's translation.For the Tolkiennymist, the coincidence of the names of the sources of Lady Charlotte Guest's and Tolkien's translations is striking: The Red Book of Hergest and the Red Book of Westmarch.
