Now let us speak of Finn, the son of Cumal. One day, soon after his return to Allen, as he and his household troops were on the exercise green before the palace, a company of fifty horsemen were seen approaching from the east, led by two taller and nobler looking than the others. Having come near, they bowed low and greeted the king; and when he asked them who they were, and from whence they had come, they answered-- "We are enemies of thine, who now desire to make peace; and our names are Angus, the son of Art Mac Morna, and Aed, the son of Andala Mac Morna. Our fathers were present at the battle of Knocka,[27] aiding those who fought against thy father, Cumal, when he was slain; for which thou didst afterwards slay them both, and didst outlaw us, their sons, though indeed we were blameless in the matter, seeing that we were not born till after the death of Cumal. However, we have come now to ask this boon of thee: that thou make peace with us, and give us the places our fathers held in the ranks of the Fena." "I will grant your request," answered Finn, "provided you pay me eric for the death of my father." "We would indeed pay thee eric willingly if we could," answered they; "but we have neither gold, nor silver, nor cattle, nor wealth of any kind to give." And then Oisin spoke and said, "Ask them not for eric, O king; surely the death of their fathers should be eric enough." But Finn replied, "Of a truth, I think, Oisin, that if any one should slay me, it would not be hard to satisfy you in the matter of an eric. But, indeed, none of those who fought at Knocka against my father, and none of their sons, shall ever get peace from me, or join the Fena, without such eric as I demand." Then Angus, one of the two, asked, "What eric dost thou require, O king?" "I ask only one or the other of two things," answered Finn; "namely, the head of a warrior, or the full of my hand of the berries of a quicken tree." "I will give you counsel, ye sons of Morna, that will stand you in good stead, if you follow it," said Oisin, addressing the two strange chiefs; "and my counsel is, that you return to the place from whence you came, and seek this peace no longer. Know that the head the king seeks from you is the head of Dermat O'Dyna, the most dangerous of all the Fena to meddle with, who is well able to defend himself, even if you were twenty times as many as you are; and who will certainly take your heads if you attempt to take his. Know also that the berries Finn seeks from you are the berries of the quicken tree of Dooros. And it is hard to say if this be not a more perilous quest than the other; for the quicken tree belongs to the Dedannans, who have sent Sharvan, the surly giant of Lochlann, to guard it day and night."
