Amatus of Sion

Saint Amatus of Sion was a monk and then abbot of Agaunum (Saint-⁠Maurice) in Switzerland, and later the tenth Bishop of Sion in the Valais. Because of a false accusation he was sent into exile at the monastery of Péronne and then at Breuil near Arras in northern France, where he lived as an ordinary monk. He reposed in the year 690.

He is a saint of the undivided Church, commemorated on 13 September (new style, Western calendar). He is not to be confused with Saint Amatus of Grenoble, a monk at Agaunum and Luxeuil and first abbot of Remiremont, remembered on the same day.
