Banshee (Bean Sídhe)

BAN-shee

A spirit woman whose keening cry is said to foretell a death in certain old Irish families.

The banshee ("woman of the sídhe") is said to attach herself to particular Gaelic family lines — the O'Neills, O'Briens, O'Connors, and O'Gradys among the families traditionally named — appearing or being heard keening (a mourning wail) before a death in the family. Unlike the Mythological or Ulster Cycle material, banshee lore comes down mainly through oral tradition and later folklore collections rather than a single medieval manuscript, so there is no one canonical source text for her — only a wide, fairly consistent body of regional testimony. Her appearance is less fixed than her cry: some accounts describe a young woman in white or grey, others an old woman wrapped in a grey cloak, and in some regions she takes the form of a "washer at the ford," glimpsed washing bloodstained clothing by a river or stream — itself an ill omen. What ties the different versions together is not a single look but the keening cry itself, the same word (caoineadh) used for the ritual mourning wail performed by human mourners at an Irish wake.

Frequently Asked Questions

Is the banshee real?

The banshee is a folklore figure, not a documented historical being — but belief in her was widespread and sincerely held in parts of Ireland well into the 20th century, passed down through oral tradition rather than any single written source.

What does a banshee look like?

Accounts vary by region: sometimes a young woman in white or grey, sometimes an old woman in a grey cloak, and sometimes a "washer at the ford" seen washing bloodstained clothing — the one constant is her keening cry rather than a fixed appearance.

What is a banshee's cry called?

The cry is called keening (from the Irish caoineadh, "to cry" or "to lament"), the same word used for the traditional Irish mourning wail performed by human mourners at a wake or funeral.
