Dubh Sunday) 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. 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. 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 to for construction projects.
