Caoineadh Airt Uí Laoghaire or the Lament for Art Ó Laoghaire is an Irish keen, or dirge written by his wife Eibhlín Dubh Ní Chonaill. The late Eighteenth century epic poem is one of the greatest love poems of the Irish Language. Eibhlín composed it capturing the life and tragic death of her husband Art on May 4, 1773.
It details the murder at Carraig an Ime, County Cork, of Art, at the hands of Abraham Morris, and the aftermath. It is one of the key texts in the Irish oral literature corpus. The poem was composed ex tempore and follows the rhythmic and societal conventions associated with keening and the traditional Irish wake respectively.
The killing of Art O' Laoghaire has its origin in one of the Penal Laws. Under the law, an Irish Catholic was forbidden to own a horse worth more than five pounds. If offered that sum for a horse of his by a Protestant, he would have to accept. O' Laoghaire refused such an offer and lost his life as a result.
