Notwithstanding his recklessness and his being engrossed in his pilgrimage, Duke Robert had taken some care for the situation in which he was leaving his son, and some measures to lessen its perils. He had appointed regent of Normandy, during William’s minority, his cousin, Alain V., duke of Brittany, whose sagacity and friendship he had proved; and he had confided the personal guardianship of the child, not to his mother. Harlette, who was left very much out in the cold, but to one of his most trusty officers, Gilbert Crespon, count of Brionne; and the strong castle of Vaudreuil, the first foundation of which dated back, it was said, to Queen Fredegonde, was assigned for the usual residence of the young duke. Lastly, to confirm with brilliancy his son’s right as his successor to the duchy of Normandy, and to assure him a powerful ally, Robert took him, himself, to the court of his suzerain, Henry I., king of France, who recognized the title of William the Bastard, and allowed him to take the oath of allegiance and homage. Having thus prepared, as best he could, for his son’s future, Robert set out on his pilgrimage. He visited Rome and Constantinople, everywhere displaying his magnificence, together with his humility. He fell ill from sheer fatigue whilst crossing Asia Minor, and was obliged to be carried in a litter by four negroes. “Go and tell them at home,” said he to a Norman pilgrim he met returning from the Holy Land, “that you saw me being carried to Paradise by four devils.” On arriving at Jerusalem, where he was received with great attention by the Mussulman emir in command there, he discharged himself of his pious vow, and took the road back to Europe. But he was poisoned, by whom or for what motive is not clearly known, at Nicaea, in Bithynia, where he was buried in the basilica of St. Mary--an honor, says the chronicle, which had never been accorded to anybody.
