In the early 13th century, the poet and crusader Muireadhach Albanach Ó Dálaigh kept a school of poetry at Lissadell north of Sligo town. He was "Ollamh Fileadh" (High Poet) to the Ó Domhnaill kings of Tír Chonaill. The school appears to have been dissolved after the Norman invasion. In the 16th century, the poet Tadhg Dall Ó hÚigínn wrote many praise poems in strict "Dán Díreach" metre for local chiefs and patrons such as the O'Conor Sligo. He was killed for a satire he wrote on the O'Haras. The annals record the death in 1561 of Naisse mac Cithruadh, the "most eminent musician that was in Éireann", by drowning on Lough Gill.
