The song to this air was written by Tomás Rua Ó Súilleabháin (1785-1848), a poet and musician from Iveragh (Uibh Ráitheach) or Derrynane, County Kerry. Ó Suilleabhain had been acting-schoolmaster at Caherdaniel and was forced to transfer to Portmagee when another schoolmaster was appointed to the permanent position. As he was leaving he placed his treasured and huge (for the times!) library of leather-bound books for transport on a boat going from Derrynane to Goleen (Goilin, Valentia Harbor), while he himself travelled by road. The boat struck a rock and was lost, tragically along with the priceless collection of books, prompting Ó Súlleabháin to seek solace in song. The air is known in modern times as a slow tempo piper’s tune. The melody is very popular as a slow air with pipers, though is usually known by the titles “Valentia Lament” or “Cuan Bhéal Inse.”
