It’s a common misconception that kelpies of Scottish myth were horses. They are always horses in popular media. Those shapeshifters emerging black-maned from rivers and lochs to lure unwary humans to a nightmarish end being devoured amongst the weeds in the dark depths.

The Bard himself said:

When thowes dissolve the snawy hoord
An’ float the jinglin icy boord
Then, water-kelpies haunt the foord
By your direction
An’ nighted trav’llers are allur’d
To their destruction.

But kelpies weren’t always...
