MS H 2.18 (cat. 1339), or the Book of Leinster (Irish Lebor Laignech), formerly known as the Book of Oughaval (Lebor na Nuachongbála), is a medieval Irish manuscript compiled ca. 1160 and now kept in Trinity College, Dublin. It was previously kept at Oughaval for many generations. Some fragments of the book, such as the Martyrology of Tallaght, are now in the collection of University College, Dublin.The manuscript has 187 leaves, each approximately 13" by 9" (33 cm by 23 cm). A note in the manuscript suggests as many as 45 leaves have been lost. The book, a wide-ranging compilation, is one of the most important sources of medieval Irish literature, genealogy and mythology, containing, among many others, texts such as Lebor Gabála Érenn (the Book of Invasions), the most complete version of Táin Bó Cuailnge (the Cattle Raid of Cooley), the Metrical Dindshenchas and an Irish translation/adaptation of the De excidio Troiae Historia, and before its separation from the main volume, the Martyrology of Tallaght.
