Kevin of Glendalough
Approx. 498 AD — June 3, 618 AD · Feast day: June 3
Kevin of Glendalough founded one of Ireland's greatest monasteries, then walked away from it to live alone in a cave above a mountain lake. A bishop who slept on stone and wore animal skins, he held his arms outstretched in prayer so long that a blackbird laid an egg in his hand — and he did not move until the chick had fledged.
