He was given the Irish name Coemgen, which means "fair-begotten",and was baptized by Cronan of Roscrea.
The Acta Sanctorum, which is based on an ancient manuscript, contains a number of legends.
I do remember an apothecary . And hereabouts he dwells—whom late I noted In tatter’d weeds, with overwhelming brows, Culling of simples ; meager were his looks , Sharp misery had worn him to the bones;
And in his needy shop a tortoise hung , An alligator stuff’d, and other skins, Of ill-shap’d fishes ; and about his shelves . A beggarly account of empty boxes , Green earthen pots, bladders, and musty seeds,
Remnants of packthread, and old cakes of roses , Were thinly scatter’d to make up a show.
