Marculf (in French Marcoult, Marcouf, Marcoul or Marcou) (d. 558) [1] was the abbot at Nantus in the Cotentin.
The accounts of his life are merged with that of Saint Helier, whom he sent to convert the inhabitants of Jersey to Christianity.
He died on May 1, 558, in the Îles Saint-Marcouf off the east coast of the Cotentin Peninsula.
His relics were transferred to the abbey of Corbény in Champagne, where they played a part in the coronation ceremonies of kings of France, crowned at Reims, and in the tradition of the royal touch.
The traditional power ascribed to French and English kings to cure scrofula (the king's Evil) by the laying on of hands derives from the efficacy of the relics of Marcouf, according to the chronicle of Joan of Arc, Chronique de la Pucelle.
