Lugh told this to Bress. But he also said: “You shall have your life in return for a much less service to us than that.” “What is it?” asked Bress. “Tell us when we ought to plough, when we ought to sow, and when we ought to harvest.” Bress replied: “You should plough on a Tuesday, sow on a Tuesday, and harvest on a Tuesday.” And this lying maxim (says the story) saved Bress’s life. Lugh, the Dagda, and Ogma still pursued the Fomors, who had carried off in their flight the Dagda’s harp. They followed them into the submarine palace where Bress and Elathan lived, and there they saw the harp hanging on the wall. This harp of the Dagda’s would not play without its owner’s leave. The Dagda sang to it: “Come, oak of the two cries! Come, hand of fourfold music! Come, summer! Come, winter! Voice of harps, bellows[139], and flutes!” For the Dagda’s harp had these two names; it was called “Oak of the two cries” and “Hand of fourfold music”. It leaped down from the wall, killing nine of the Fomors as it passed, and came into the Dagda’s hand. The Dagda played to the Fomors the three tunes known to all clever harpists—the weeping-tune, the laughing-tune, and the sleeping-tune. While he played the weeping-tune, they were bowed with weeping; while he played the laughing-tune, they rocked with laughter; and when he played the sleeping-tune, they all fell asleep. And while they slept, Lugh, the Dagda, and Ogma got away safely. Next, the Dagda brought the black-maned heifer which he had, by the advice of Angus son of the Young, obtained from Bress. The wisdom of Angus had been shown in this advice, for it was this very heifer that the cattle of the people of the goddess Danu were accustomed to follow, whenever it lowed. Now, when it lowed, all the cattle which the Fomors had taken away from the Tuatha Dé Danann came back again. Yet the power of the Fomors was not wholly broken. Four of them still carried on a desultory warfare by spoiling the corn, fruit, and milk of their conquerors. But the Morrígú and Badb and Mider and Angus pursued them, and drove them out of Ireland for ever.[140] Last of all, the Morrígú and Badb went up on to the summits of all the high mountains of Ireland, and proclaimed the victory. All the lesser gods who had not been in the battle came round and heard the news. And Badb sang a song which began: “Peace mounts to the heavens, The heavens descend to earth, Earth lies under the heavens, Everyone is strong ...”, but the rest of it has been lost and forgotten.
