St. Mechtildis was a Benedictine abbess and renowned miracle worker. Mechtildis was the daughter of Count Berthold of Andechs, whose wife, Sophie, founded a monastery on their estate at Diessen, Bavaria, and placed their daughter there at the age of five. In 1153, the Bishop of Augsburg placed her as Abbess of Edelstetten Abbey. Mechtildis was known for her mystical gifts and miracles. She would later die at Diessen, Germany, on 31 May 1160.
