These legends [told of Killeen Cormac ] look like an interpretation from one more ancient concerning the hounds of Cuglos (son of Donndesa, King of Leinster), who was master of the hounds to Ederscoel, the great king of Erin. [...]

His dogs hunted a wild boar from Tara to the Hill of Urske, where they left the marks of their paws on the stones of a druidical circle crowning its summit. The same traces are to be found on some rocks at Manger, near Rathbran.

While pursuing their game up the hill over Beallach Dubhthaire, the ancient name of Baltinglass, Cuglos with his dogs, blinded by the mist and fog, chased their game into a cave on the summit of the mountain, and being there lost, his memory was perpetuated by giving his name to the scene of his untimely fate.
