'What counsel do you give this lad?' asked Midhir. 'I have this for him' replied Eochaid 'On the day of the Samhain let him go into the Brugh and let him go armed. That is a day of peace and amity among the men of Ireland, on which none is at enmity with his fellow. And Elcmar will be at Cnoc Síd in Broga unarmed save for a fork of white hazel in his hand, his cloak folded about him, and a gold brooch in his cloak, and three fifties playing before him in the playing field; and let Aengus go to him and threaten to kill him. But it is important that he does not kill him provided Elcmar promises him his will. And let this be the will of Aengus, that he be king a day and a night in the Brugh; and see that he yields not the land again to Elcmar until he submit himself to my decision. And when he comes let Aengus plea that the land has fallen to him in simple payment for the sparing of Elcmar's life, and that what he has asked for is kingship for a day and a night, and it is in days and nights that the world is spanned.
