The Dullahan (also Durahan, Gan Ceann) is a headless spirit that wanders around Ireland, often with its head tucked beneath its arm.
The Dullahan is headless, usually seen riding a headless black horse and carrying his head under one arm. Sometimes he drives a black coach drawn by headless horses. The Dullahan's face is the color and texture of molding cheese; his head has a large mouth and huge eyes that dart around like flies. And in some of the stories his horse has a head too. Its head is longer than its body by 6 yards and has flaming eyes and short ears.
The Dullahan knocks at doors of cottages, and if the door is opened then he hurls a bucket of blood into the poor resident's face. This is a portent of death.
In other legends he sides with the legendary ghost, the Banshee, and they drive a black cart (called the Coiste Bodhar) drawn by six black horses and whips them with his whip made of a human spinal cord .
Some people believe that the Dullahan is the embodied spirit of a celtic god, Crom Dubh, who demanded human sacrifices each year. The worship of Crom Dubh continued in Ireland until the sixth century, when Christian missionaries arrived from Scotland. But Crom Dubh still wanting souls became the Dullahan or far dorocha (Which translates into Dark Man.) The myth may have inspired The Legend of Sleepy Hollow. When he stops riding, a mortal dies. The only fear it has is gold, which any lonely traveler at night would be wise to have to ward off him off.
W. J. Fitzpatrick, a famous storyteller claims to have seen a Dullahan. He recounts:
I seen the dullahan myself, stopping on the brow of the hill between Bryansford and Moneyscalp late one evening, just as the sun was setting. It was completely headless but it held up its own head in its hand and I heard it call out a name. I put my hand across my ears in case the name was my own, so I couldn't hear what it said. When I looked again, it was gone. But shortly afterwards, there was a bad car accident on that very hill and a young man was killed. It had been his name that the dullahan was calling.
