Crom Dubh

Crom Dubh (Old Irish: [krom duβ], Scottish Gaelic: [kʰɾɔum t̪uh]; meaning "black crooked [one]"; also Crum Dubh, Dark Crom) is a mythological and folkloric figure of Ireland, based on the god Crom Cruach, mentioned in the 12th-century dinnseanchas of Magh Slécht.^[1]

According to one legend, Cainnech of Aghaboe saw a number of demons flying past and when he inquired of their errand, one of them told him that Crom Dubh had died and they were after collecting his soul. Cainnech bid him on their return to tell him how they had fared. Some time later the demon returned limping badly. He told Cainnech that they were just about to seize Crom Dubh's soul when St. Patrick appeared with a host of angels and saints and drove them off, Crom Dubh's good works having outweighed his sins.^[2]

Another location associated with Crom Dubh is Downpatrick Head in County Mayo. According to Irish legend, St. Patrick came to the headland to confront Crom Dubh, who is variously identified as a pagan chieftain, god, pirate, or robber. Crom Dubh attempted to throw St. Patrick into an eternal fire, but Patrick countered by drawing a cross on a stone and casting it into the fire, which became Poll a' Sean Tine (the hole of the old fire). Crom Dubh was then driven by St. Patrick into his home of Dun Briste, which Patrick separated from the mainland by driving his crozier into the ground. The site of Downpatrick Head became an important place of ritual and pilgrimage during the Festival of Lughnasadh - similar to Croagh Patrick. The alternate names associated with Crom Dubh at Downpatrick Head include Cormac Dubh, Geodrisg, Deodrisg and Leodrisg. In other stories St. Patrick banishes the snakes of Ireland to Dun Briste.^[3]

According to another local folktale, Crom Dubh was a servant of St. Patrick who gathered wood for the Saint to cook food for the needy. Crom Dubh interrupted St. Patrick during Mass on Crom Dubh Sunday by asking when the Sluagh Sidhe would go to Paradise, to which St. Patrick responded they would not go there until the Last Judgment. Before that day, the people would put their sickles in the corn and their spades in the ground, and the invisible Sidhfir would do the agricultural work for them, but after that day, the Sidhfir would no longer do any work.^[4]

Dé Domhnaigh Crum-Dubh (Crom Dubh Sunday)^[5] was traditionally celebrated on the last Sunday in July or the first Sunday in August and is alternatively known as Garland Sunday or Lammas Sunday. The traditional gathering on Crom Dubh Sunday was known as Comthineol Chruim Duibh or the Congregation of Crom Dubh.^[6] On this day, families held a feast of the first fruits that included new bacon, new cabbage, and new potatoes, and any man who could not provide food for his family was known as a "wind farmer." Crom Dubh was understood as a god of sacrifice, and in historic times celebrants left flowers on the Altóir na Greine or Altar of the Sun on Crom Dubh Sunday.^[7] A festival or oenach called Buaile na Greine was also held for several days adjoining Crom Dubh Sunday on Mount Callan and included feasting, drinking, racing, hurling, singing and dancing; this festival was later replaced by a Christian festival to St. Muchan, which included prayers at the holy well. The Altóir na Greine was destroyed by a farmer in the 1800s to build a wall, and the stones were later reused for construction projects.^[8]

There is no mention of Crom Dugh in Celtic Myth in texts before the 1100s. Texts that explain the Celtic Gods such as the Mythological Cycle or Ulster Cycle have no mention of Crom, which means he was not part of the authentic pre-Christian pantheon. It is likely, and some believe, that Crom is entirely a fabrication of Christian writers. Since these Christian writers wanted to demonize pre-Christian belief, some believe this is an entire fabrication. There is no direct archaeological evidence of Crom, and the autobiography of St. Patrick, who lived among them, makes no mention of Crom or human sacrifices.

The autobiography of St. Patrick, written by him at the time makes no mention of Crom, nor do other sources of the time. St. Patricks other biographers do not mention crom, it is only 200 years later, in 900 that Crom is mentioned in regards to St. Patrick.
