The well-known translation by O'Curry of this part of the Book of Leinster version of the "Tain bo Cuailgne" is given in the third volume of his "Manners and Customs," pp. 414-463. There are, as has often been pointed out, many inaccuracies in the translation, and the present version does not claim to correct all or even the greater part of them; for the complete version of the Great Tain by Windisch which has so long eagerly been expected should give us a trustworthy text, and the present translation is in the main founded on O'Curry; to whose version reference may be made for literal translations for such parts of the verse passages as are not noted below. A few more obvious corrections have been made; most of those in the prose will appear by comparing the rendering with O'Curry's; some of the corrections in the literal versions adopted for the poems are briefly indicated. Two poems have been literally translated in full: in these the renderings which have no authority other than O'Curry's are followed by a query, in order to give an indication of the extent to which the translation as given may for the present be regarded as uncertain. For all the more valuable of the corrections made to O'Curry's translation I am indebted to the kindness of Mr. E. J. Quiggin, Fellow of Caius College, Cambridge.
