St Elidius (Lide) lived in a cell as a hermit on the now uninhabited island of St Helen’s in the Scilly islands. A communal hermitage developed.
It is said he was the son of a British Bishop. Excavations have found a grave. A small church was built in the 11C and a marble shrine housed his relics.
A 13C Norse saga tells of the King of Norway, Olaf Tryggvasson, being converted, by a holy man. The identity of the holy man is not known but a holy man living on St Helen’s may have been the one.
