inhospitality about them." On account of this the books became illegible after Longarad's death. Angus the Culdee lived about the year 800, but Stokes ascribes the Féilĭrè to the tenth century; a view, however, which Mr. Strachan's studies on the Irish deponent verb, which is of such frequent occurrence in the Féilĭrè, may perhaps modify. At what time the scholiast wrote his note on the text is uncertain, but it also is very old. It is plain, then, that at this time a number of illegible books--illegible no doubt from age--existed; and to account for this illegibility the story of Columcille's curse was invented. The Annals of Ulster quote another book at the year 527 under the name of the Book of St. Mochta, who was a disciple of St. Patrick. They also quote the Book of Cuana at the year 468 and repeatedly afterwards down to the year 610, while they record the death of Cuana, a scribe, at the year 738, after which no more quotations from Cuana's book occur. The following volumes, almost all of which existed prior to the year 1100, are also alluded to in our old literature:--The Book of Dubhdaleithe; the Yellow Book of Slane; the original Leabhar na h-Uidhre, or "Book of the Dun Cow"; the Books of Eochaidh O'Flanagain; a certain volume known as the book eaten by the poor people in the desert; the Book of Inis an Dúin; the short Book of Monasterboice; the Books of Flann of Monasterboice; the Book of Flann of Dungiven; the Book of Downpatrick; the Book of Derry; the Book of Sábhal Patrick; the Black Book of St. Molaga; the Yellow Book of St. Molling; the Yellow Book of Mac Murrough; the Book of Armagh (not the one now so called); the Red Book of Mac Egan; the Long Book of Leithlin; the Books of O'Scoba of Clonmacnois; the "Duil" of Drom Ceat; the Book of Clonsost; the Book of Cluain Eidhneach (the ivy meadow) in Leix; and one of the most valuable and often quoted of all, Cormac's great Saltair of Cashel, compiled by Cormac mac Culinan, who was at once king of Munster and archbishop of Cashel,[4] and who fell in battle in 903, according to the chronology of the "Four Masters." The above are certainly only a few of the books in which a large early literature was contained, one that has now perished almost to a page. Michael O'Clery, in the Preface to his Book of Invasions written in 1631, mentions the books from which he and his four antiquarian friends compiled their work--mostly now perished!--and adds:--
