Aimo (commonly known as Saint Aimo, also Aymon or Hamon) was a mystic and monk.

Born in the village of Landecob, Brittany near Rennes, Aimo entered the Benedictine monastery of Savigny, in Savigny, Normandy.^[1] Suspected of having leprosy, he was ejected from the house lest the sickness spread. Aimo went to stay in a nearby woods with two other monks who did have the disease. There he took care of them.^[2]

When it was seen that he did not have leprosy, Aimo was allowed to become a professed monk and was ordained a priest. He became known as an effective confessor and spiritual director. He was entrusted with supervising the lay brothers, who were as much servants as monks, many with little religious sensibility; but he loved them and many learned spirituality from him.^[3]

His devotion to the saints led to the building of a number of churches and chapels in Normandy in their honor.^[2] Aimo is mainly remembered for charitable kindness especially to the sick and for his mystical experiences.
