section 163

Then Lug and the Dagda and Ogma went after the Fomoire, because they had taken the Dagda's harper, Úaithne. Eventually they reached the banqueting hall where Bres mac Elathan and Elatha mac Delbaíth were. There was the harp on the wall. That is the harp in which the Dagda had bound the melodies so that they did not make a sound until he summoned them, saying,
