	Mac Creiche lived as a hermit in a structure made of four stones at a place called Cluain Í. The dwelling had "a stone at his back, a stone to each side, and a stone in front of him", and seems to have been designed for discomfort. He lived a frugal life: "Mac Creiche, the devout, loved / A hard and undefiled dungeon. / From Shrovetide to Easter would he subsist / Upon only bread and cresses."
