Crom Dubh
Crom Dubh, meaning ":wikt:dubh|dark :wikt:crom|crooked " is a mythological and folkloric figure of Ireland, based on the god Crom Cruach, or "king idol of Ireland", mentioned in the 12th-century dinnseanchas of Magh Slécht.
The festival for Crom Cruach is called Dé Domhnaigh Crum-Dubh as in the Scottish Gaelic saying DiDòmhnaich Crum Dubh, plaoisgidh mi an t-ugh. "Crooked black Sunday, I’ll shell the egg."
Crom Cruach is called the chief Celtic idol of Ireland by Michael J. O'Kelly, and was located on Magh Slécht in County Cavan, surrounded by twelve other idols.
