This poem is found in a MS. given to the Highland Society by Lord Bannatyne, and now in the archives of the Advocates’ Library. The date of the MS. is 1208, but there is every reason to believe that the poem is of much higher antiquity. The preserved copy bears to have been written at Glenmasan, a mountain valley in the parish of Dunoon, in Cowal. The MS. contains other fragments of tales in prose, but we shall refer only to the poetical story of Deirdre, or, as it is usually called in Gaelic, “Dàn Chloinn Uisneachain.” The tale is a famous one in the Highlands, and the heroes of it, the sons of Usnoth, have given name to Dun Mhac Uisneachain, or Dun Mac Sniochain, said to be the Roman _Beregonium_, in the parish of Ardchattan in Argyleshire. We give the following version of the poem as it appears in the Report of the Highland Society on the Poems of Ossian (p. 298). _Do dech Deardir ar a héise ar crichibh Alban, agus ro chan an Laoidh_-- Inmain tir in tir ud thoir, Alba cona lingantaibh Nocha tiefuinn eisdi ille Mana tisain le Naise. Inmain Dun Fidhgha is Dun Finn Inmain in Dun os a cinn Inmain Inis Draignde Is inmain Dun Sùibnei. Caill cuan gar tigeadh Ainnle mo nuar Fagair lim ab bitan Is Naise an oirear Alban. Glend Laidh do chollain fan mboirmin caoimh Iasg is sieng is saill bruich Fa hi mo chuid an Glend laigh. Glend masain ard a crimh geal a gasain Do nimais colladh corrach Os Inbhhar mungach Masain. Glend Eitchi ann do togbhus mo ched tigh Alaind a fidh iar neirghe Buaile grene Ghlind eitchi. Mo chen Glend Urchaidh Ba hedh in Glend direach dromchain Uallcha feara aoisi ma Naise An Glend Urchaidh. Glend da ruadh Mo chen gach fear da na dual Is binn guth cuach Ar cracib chruim Ar in mbinn os Glenndaruadh Inmain Draighen is tren traigh Inmain Auichd in ghainimh glain Nocha tiefuin eisde anoir Mana tisuinn lem Inmain. _English Translation._ _Deirdre looked back on the land of Alban, and sung this lay_:--
