Michael Dames recounts aspects of the bull in Celtic spiritual practice: "In Munster and Connacht folklore Crom's bull was believed to be immortal. By trickery St Patrick once killed and ate it, and then ordered the bones to be thrown into the hide, whereupon the animal returned to life. Around Galway Bay at Samain every household skinned and roasted a bull in honour of Crom Dubh, and one may assume that Crom Dubh and the Bull were originally synonymous." (Dames, Michael. Mythic Ireland. London: Thames and Hudson, 1992. 100-105.)
