Irish name, Lebor Laignech, Leabhar Laighneach. Also known as Book of Noughaval/ Oakvale, Lebor na Nuachongbála. Compiled after 1150, this codex is the second best source of Irish myth and legend after the Book of the Dun Cow. Some of the material, such as the Dindshenchas, the lore and history of places, dates from the 11th century. Also important are texts of the pseudo-history Lebor Gabála [Book of Invasions], a version of the Táin Bó Cuailnge, the Deirdre story, and the Bórama. The surviving manuscript is divided between Trinity College and the Franciscan Library, Dublin. Leinster, one of the five ancient provinces, constitutes much of eastern Ireland. First published in facsimile (Dublin, 1870), the Book of Leinster has been edited in six volumes by R. I. Best, Osborn Bergin, M. A. O'Brien, and A. O'sullivan (Dublin, 1954–83).
