Summary
What is a banshee? In Irish folklore, a banshee (from the Irish bean sí, "woman of the fairy mound" or "fairy woman") is a female spirit whose wailing or keening is said to announce that a member of a particular family is about to die. She is a messenger of death, not a killer.
This post is about folklore. The banshee is a figure of belief and storytelling, not a creature documented by science.
Where does the banshee legend come from?
The name goes back to Old Irish ben síde. The síde are the ancient mounds that dot the Irish countryside and were linked with the otherworld of the fairies. Written mentions are old: Wikipedia's summary cites accounts as far back as the 1380 Cathreim Thoirdhealbhaigh (Triumphs of Turlough) by Seán mac Craith.
Why does the banshee wail?
Her cry echoes a real funeral custom. In Ireland the keen (caoineadh) was a lament sung over the dead at wakes, often led by a keening woman, the bean chaointe. A University of Limerick paper by Mary Mc Laughlin notes that folklorists Patricia Lysaght and Gearóid Ó Crualaoich have drawn parallels between the human keening woman and the bean sí. In the legend, the banshee keens before or at the moment of death, sometimes for a relative who has died far away, so her cry is the family's first warning.
Which families does the banshee follow?
Tradition links her to families of Gaelic descent, especially surnames beginning with O, Mac or Mc, such as O'Brien or McGrath. Folklore collectors still record banshee stories today: Ask About Ireland reproduces one collected in Carlow in 2009.
What does a banshee look like?
Descriptions vary from region to region:
- long streaming hair, which she is sometimes seen combing
- a grey cloak over a green dress, with eyes red from weeping
- a woman in white with red hair and a ghastly complexion
- most often short, from about one to four feet tall, though some tales make her unnaturally tall
Are there banshees outside Ireland?
Similar figures exist nearby. In Scottish folklore the bean nighe, or "washer at the ford", is seen washing the bloodstained clothes of people about to die. Welsh folklore has the cyhyraeth.
