The Duan Albanach (Song of the Scots) is a Middle Gaelic poem found with the Lebor Bretnach, a Gaelic version of the Historia Brittonum of Nennius, with extensive additional material (mostly concerning Scotland).
Written during the reign of Mael Coluim III, it is found in a variety of Irish sources, and the usual version comes from the early 15th century Books of Lecan and Ui Maine. It follows on from the Duan Eireannach, which covers the earlier mythological history of the Gael.
It is a praise poem of 27 stanzas, probably sung at court to a musical accompaniment by the harp. If performed in a public context, it is possible that the audience would have participated in the performance.
A eolcha Alban uile, O all ye learned of Alba ! a shluagh feuta foltbhuidhe, Ye well skilled host of yellow hair ! cia ceud ghabhail, an eól duíbh, What was the first invasion – is it known to you? ro ghabhasdair Albanruigh ? Which took the land of Alba ? Albanus ro ghabh, lia a shlógh, Albanus possessed it, numerous his hosts; mac sen oirdérc Isicon, He was the illustrious son of Isacon, brathair is Briutus gan brath, He and Brutus were brothers without deceit, ó ráitear Alba eathrach. From him Alba of ships has its name.
In the final stanzas it is seen that the poem dates from the time of Malcolm III, in the second half of the 11th century.
Se bliadhna Donnchaid glain gaoith The six years of Donnchad the wise, xuii bliadhna mac Fionnlaoich, Seventeen years the son of Findláech; tar és Mec Beathaidh go m-blaidh, After Mac Bethad, the renowned, uii mís i f-flaithios Lughlaigh. Seven months was Lulach in the sovereignty. Maolcholuim anosa as rí, Máel Coluim is now the king, mac Donnchaidh dhata dhrechbhi, Son of Donnchad the florid, of lively visage, a ré nocha n-fidir neach, His duration knoweth no man acht an t-eólach as éolach. A eolcha. But the Wise One, the Most Wise. O ye learned.
