Aimo was a 12th-century Benedictine monk and mystic from Brittany. After being born in the village of Landecob, he joined the monastery of Savigny in Normandy. During his time there, he was briefly expelled from the community due to suspicions that he suffered from leprosy, leading him to live in the woods to care for two other afflicted monks. Once his health was cleared, he returned to the monastery, was ordained a priest, and became a respected spiritual director and confessor.
