Cóir Connacht ar chath Laighean is a fourteenth century Irish poem. [1][2]
It is an address to Aedh mac Eoghan Ua Conchobair, King of Connacht (d. 1309 and is thought to be "the earliest extant bardic poem containing an 'arming the hero' sequence with reference to the new Norman style of arms.'
It is of a piece with An sluagh sidhe so i nEamhuin?, composed nearly four hundred years later.
