Dullahan | The Headless Horseman

The Dullahan is a terrifying headless horseman from Irish folklore, a demonic fairy riding a black horse, carrying his own glowing head, and using a spine as a whip; he's a death messenger who calls out names, leading to the person's demise, but can be deterred by gold. This figure, possibly evolved from ancient Celtic sacrificial rites to the god Crom Dubh, serves as a precursor to other headless horsemen in folklore, most famously inspiring Washington Irving's "Legend of Sleepy Hollow".
