William returned to England, and entered the Benedictine monastery at Durham, taking the name Bartholomew. He had a great devotion to Saint Cuthbert, received a vision of him, and eventually moved into Cuthbert's old cell on the island of Farne, spending 41 of his remaining 42 years there. The only break came when a dispute with the only other hermit in the hermitage caused him to pack up and return to Durham; his bishop eventually ordered him to act like he had good sense, and return to his cell.
