¶1] Glenn Breogain, whence the name? Not hard to say. From Breogan, ancestor of the sons of Mil, is named Mag Breg and Glenn Breogain, and it is also called Glenn in Mor-Daim, the glen of the great stag, that is, the stag of Smirgoll, son of Tethra, who was king over Erin. Now this stag was killed by the troop of the wife of Fuat, scouring Mag Breg westward to the entrance of the dun. And this plain is likewise called Druim na Mor-muicce, the ridge of the great swine: for the shape of a swine appeared to the sons of Mil on every hill and on every high place in Erin, when they rowed round it and desired to take possession of the land.
