In the isle of Jersey and on the coasts of Normandy the name of
this servant of God has been in singular veneration from the time
of his happy death. He was converted to the faith by St. Marcou, a
holy abbot in Armorica, and being inflamed with an ardent desire
of serving God in the practice of perfect virtue; retired into the
isle of Jersey, and choosing for his abode a cave on the summit of a
rock of difficult access, there led an eremitical life in rigorous
fasting and assiduous prayer. In this lonely retreat he was murdered
by robbers or infidel barbarians. The chief town in the island, which
is situate seven leagues from Cotentin, bears his name. The dean of
the island is still invited to all diocesan synods of Coutances, the
island having been formerly subject to the spiritual jurisdiction of
that see. See the new Martyrology of Evreux; Piganiol, Descrip. de
la France, t. 9, p. 557. The acts of S. Helier, in the Bollandists,

and that of the Cistercian abbey of Beaubec, in the diocess of Rouen,
which is possessed of his relics.
