The Dead at Clonmacnoise

The Dead at Clonmacnoise is a 14th-century poem by Aongus Ó Giolláin. It commemorates the many royal kings and princes of Ireland that were buried there.

Excerpt (translation)
There they laid to rest the seven Kings of Tara there the sons of Coirpre sleep – battle-banners of the Gael, that in Kieran's plain of crosses now their final hosting keep.
