The Death Of Cu Chulainn

Maebe conspires with Lugaid son of Cú Roy, Erc, son of Cairbre Nia Fer, and all the children of others that Cuchulainn killed, to take to the grave. His fate is sealed by breaking the oath geasa or fell on him and that included the prohibition of eating dog meat, as in Ireland in the beginning there was a deeply rooted belief opposed to refusing the hospitality offered by others, so when an ugly old woman offered a plate of dog meat, he has no choice but to break his geis or oath. So it is spiritually weak to fight to come.
Lugaid sent to three magical spears and prophesied that a king will fall with each of them. With the first, kills LAEG, Cuchulainn's charioteer, king of the charioteers. With the second, kill the horse Cú Chulainn, Liath Macha, the king of horses. And third, mortally wounded himself Cú Chulainn. So this is tied himself to a rock to stand. Stone, traditionally identified with one that is still in Knockbridge, only when a crow resting on his shoulder his enemies know he is dead. Then Lugaid cuts his head, but upon doing so, Cuchulainn's sword falls from his hand cut off the hand of Lugaid.
