Aimo was a mystic and monk. Born in an area near Rennes, France, Aimo entered the Benedictine monastery of Savigny, in Savigny, Normandy. There he took care of two monks who had leprosy, and it was believed that Aimo himself had contracted the disease. This caused Aimo to serve as a lay brother. When was seen that he did not have leprosy, Aimo was ordained a priest. Aimo mainly remembered for charitable kindness especially to the sick and for his mystical experiences.
