Glashtyn | Shape-Shifting Water Horse

The Glashtyn (or Glashtin) is a mischievous, shape-shifting water horse from Manx folklore (Isle of Man), similar to the Scottish Kelpie, appearing as a horse with reversed hooves or transforming into a man to lure victims to watery deaths, but also known for hoarding treasure like pearls. It's a dangerous water spirit, often linked to shipwrecks, that can be controlled if its bridle is captured, revealing its connection to other Celtic water horses. 

Characteristics & Forms

  • Water Horse: Most commonly seen as a horse, often with reversed hooves or sticky hide to trap riders.
  • Humanoid: Can take the form of a handsome man to seduce, or sometimes a hairy man or old woman.
  • Treasure Hoarder: Has a fondness for pearls, stealing them from shipwrecks and victims.
  • Manx Name: Also called Cabbyl Ushtey (Water Horse) or Tarroo-ushtey (Bull-horse). 

Behaviour & Legends

  • Lures Victims: Like the Kelpie, it tries to get people to ride it into lochs or rivers to drown them.
  • Strength: Possesses immense strength, capable of carrying multiple people at once.
  • Control: Can be controlled if someone gets hold of its bridle, especially one marked with a crucifix, binding it to service. 

Connection to Kelpies

  • The Glashtyn is part of a broader tradition of Celtic water spirits (like the Scottish Kelpie or Irish Each-Uisge), sharing the shape-shifting water horse theme but with unique Manx characteristics, particularly its association with treasure.
