origin, briefly told in the Book of Leinster, forms a picture less colossal but more disgusting than that sketched by Milton of the relations between Death and Sin and Satan. Now the four provinces of Erinn which were usually hostile to Ulster wished to choose a king to rule over the kingdom at Tara; and among those who met together were Ailill and Medb, Cúroi, and Erc king of Leinster, in whose palace at Tara the meeting was held. The Ultonians were of course not consulted, but the vision of the seer at the bull-feast indicated as the over-king that was to be chosen, a warrior who was then in Ulster, standing, as it happened, by Cúchulainn's sickbed. Messengers were sent to him, and it was when they announced their errand that Cúchulainn sat up and delivered a charge to Lugaid as to how he was to conduct himself in his office of king.[1]
This friendship between Cúchulainn and Lugaid is very remarkable; it is illustrated also in the Táin epic, where Lugaid is called son of Nós and described as king of Munster.[2] Ailill and Medb are represented availing themselves of that friendship to make use of Lugaid as their intermediary when they wish to negociate with their great enemy Cúchulainn. We have had an instance also of it in the story of Cúchulainn giving his own bride Derborgaill to Lugaid to wife (p. 465), and to this may be added one which mentions Forgall Monach betrothing Emer to Lugaid mac Nóis king of Munster, and the latter declining to have anything to do with her as soon
