This dwarf was a magician, and a dreadful tyrant, and after having perpetrated great cruelties on the people he was at last vanquished and slain by a neighbouring chieftain; some say by Fionn Mac Cumhail.
The chief then consulted a druid, and according to his directions, he slew the dwarf a third time, and buried him in the same place, with his head downwards; which subdued his magical power, so that he never again appeared on earth.
The laght raised over the dwarf is still there, and you may hear the legend with much detail from the natives of the place, one of whom told it to me.In some modern versions of the story Abhartach rises from his grave to drink the blood of his subjects,[2] while the chieftain who slays the revenant is named as Cathain.
[2] Curran is also the author of Vampires: A Field Guide to the Creatures That Stalk the Night (2005), which recounts a more detailed version of the legend than that collected by Weston.
Abhartach serves as the antagonist in the 2021 Irish film Boys from County Hell where he is depicted as a tall vampire-like figure who can drain people of their blood just by being within a certain proximity of them and who was famously defeated by the chieftain Ó Catháin.
