Now that was damaging to the Fomoire, and they picked a man to reconnoitre the battle and the practices of the Túatha Dé—Rúadán, the son of Bres and of Brig, the daughter of the Dagda—because he was a son and a grandson of the Túatha Dé. Then he described to the Fomoire the work of the smith and the carpenter and the brazier and the four physicians who were around the well. They sent him back to kill one of the áes dána, Goibniu. He requested a spearpoint from him, its rivets from the brazier, and its shaft from the carpenter; and everything was given to him as he asked. Now there was a woman there grinding weapons, Crón the mother of Fíanlach; and she ground Rúadán's spear. So the spear was given to Rúadán by his maternal kin, and for that reason a weaver's beam is still called 'the spear of the maternal kin' in Ireland.
