Around 581, he entered the Abbey of St. Maurice, Agaunum, and at the age of thirty retired into a hermitage,[2] where his reputation for a life of penance and prayer, privileged with the grace of miracle working, drew the attention of Eustace of Luxeuil, who persuaded Amatus to join his community.

[3] One of his missionary journeys brought him to the court at Metz, and there he converted a former Count Palatine of King Theodebert II, the Frankish noble St. Romaric.

He ruled this Abbey for many years, and established there the difficult pious practice of the “Laus perennis” or Perpetual Praise, which consisted in the maintaining in the Church an uninterrupted service of Psalmody and Prayer, day and night.

Saint Amatus died in the year 627,[5] and at his own request was buried just outside the church door.

[3] Saint Amatus was canonized on 3 December 1049 by Pope Leo IX and his memorial day is 13 September.
