Saint Guthlac of Croyland. Born to the Mercian noblity, he served a soldier and used his freedom and skill in arms to amass a fortune in looted treasure. In 697, however, he had a conversion, gave up the violent and worldly life, and lived in a swamp that was thought at the time to be the home of monsters and demons.
