abhartach

abhartach
Many years ago there lived in the lands east of the Foyle, between Dungiven and Garvagh, in the glen of the eagle (Glenullin) a chieftain or petty king called Abhartach. His name implies that he was small or a dwarf. It may be that he had been injured in battle or through accident, or possibly because of wizardry, for the people of his time were great warriors and they liked their rulers to be manly, brave and strong. However this is conjecture and all we know of him is that he was quite an evil man, a wizard even, hated and feared by his own clan and the neighbouring clans.
