Merrow and the Stolen Cap of the Irish
By Ralf Ittermann · last reviewed on
Merrow is a spirit of Celtic (Irish) tradition.
Without her red cap, she remains bound to land until she finds the cap again. The Merrow counts as a sea being of Irish legend, and this article gathers what the tradition attaches to that description.
The Merrow is the mermaid of the Irish coast: a green-haired woman who rises from the sea onto land and sometimes marries a mortal. Her hallmark is the red magic cap cohuleen druith, without which she cannot return. She is first documented in 1825 by Croker.

The Stolen Cap and the Lady of Gollerus
The name is anglicised from murúch, Middle Irish murdúchann, interpreted as sea singer. The Merrow is first documented in 1825 by Croker: the Lady of Gollerus marries a man who steals her cap; years later she finds the hiding place and returns to the sea.
From Yeats to the Red Cap of Fantasy
Yeats popularised the Merrow in 1888 and coined the red cap; in Croker she wears no colour. Clarification: the soul-cages tale of a male Merrow is not a genuine folk legend but an invention of Thomas Keightley. She is the supernatural bride, bound only by the theft of an object.
The Stolen Object Instead of a Banishing Spell
Tradition knows no warding with iron: whoever hides the cohuleen druith keeps the Merrow on land; if she finds the cap again, the bond is broken. Amulet, salt and consecrated bells are regarded as protective means.
Mermaids of the British Isles and Beyond
Her singing places the Merrow alongside the sirens of legend; the cap motif connects her with Selkie and Roane, as well as the Manx Ben-Varrey. She differs from the deadly Marie Morgane: there is no deliberate devouring.
Frequently Asked Questions about the Merrow
What is the cohuleen druith?
The Merrow’s magic cap, which enables diving. Without it she cannot return to the sea, which is why a man hides it in the marriage legends. In Yeats it is red, Croker names no colour.
Literature (selection)

Sought as the Merrow mermaid, she remains above all an Irish mermaid: green hair, red cap, between sea and human world, able to marry but never permanently bound.
