Drawing from details in the mortuary roll (a monastery's record of prominent members who died), we learn little of Vitalis' origin except that he was born c.1060 and had a brother and a sister in a family that was not very prominent. At some point he was ordained and became chaplain to Robert of Mortain.
Robert of Mortain had founded the Church of Saint-Evroult in 1082, and made Vitalis a canon there. After a time, however, Vitalis felt the need for a more purely ascetic life. In 1095 he left Saint-Evroult and began a hermit colony with two others, Bernard of Thiron (who had already been a hermit for a time) and Robert of Arbrissel, the founder of Fontevraud Abbey.
Vitalis became known for his preaching to those who came to hear and/or join the hermitage, and for helping locals. One of his known activities was persuading prostitutes to enter proper marriages. He also traveled, apparently concentrating on Normandy but also visiting England. He tried to reconcile Robert Curthose with his brother, Henry I of England, whom it could be argued "stole" the kingship from the elder Curthose.
One of the incidents that was sufficiently noteworthy to be mentioned in the mortuary roll was his influence on his first patron, Robert of Mortain. The story goes that Robert was physically abusing his wife (probably Matilda, his first wife), and that Vitalis ended that behavior in one of two ways. One version of the incident had Vitalis threatening Robert with dissolving the marriage. A different version says that Vitalis cut ties to Robert and left over his disgust at Robert's behavior. Robert repented, and sent people to bring Vitalis back and begged his forgiveness (and presumably mended his ways).
Between 1105 and 1120, Vitalis founded a nunnery called Abbaye Blanche ("White Abbey"; possibly so-called because they wore habits of undyed wool) at Mortain and set up his sister, Adeline, as abbess. She was later canonized by the Catholic Church.
Between 1112 and 1122 (the year of his death) he founded the Savigny Abbey (see the remains above), a necessity because his life and works as a hermit drew so many people who wished to stay that some organizing principle was needed to manage so many. The Benedictine Rule was initially followed, but by 1150 it became Cistercian.
Vitalis' own sainthood was established in 1738 by the Cistercians, but his canonization by the Catholic Church was never recognized.
His first patron, Robert of Mortain, has a connection that is worth mentioning. Not just some ordinary nobleman, he was half-brother to William the Conqueror, and has some significance in history, which I'll explore further tomorrow. See you then.
