Jean, a learned French antiquary, born near Falaise in 1724. He was educated at Caen, and in 1745 he became a Benedictine monk of the abbey of St Martin de Sez. His merit and learning procured his translation to the abbey of Bec, where he resided till 1764. He was elected an honorary member of the Society of Antiquaries of London in 1765; and the same year returned to the abbey of St Stephen at Caen, where he continued till his death in 1775. He left behind him, in manuscript, large and accurate accounts of some of the principal Norman abbeys. The History of the Royal Abbey of Bec, which he presented to Dr Ducarel in 1764, is only an abstract of his larger work.
