When Curthose was at Palermo, on his way home, Odo of Bayeux breathed his last. The Norman duke, having buried his uncle in St. Mary's Church, pursued his way, and found himself quite at home among the Normans, whose families had been settled by warlike adventurers in Southern Italy. All these Norman warriors treated the heir of the great William with high honour; and all their daughters manifested interest in a hero who had won such fame as a Champion of the Cross. But of all the Normans of Southern Italy, none showed Curthose so much hospitality as William, Count of Conversano, a kinsman of the Guiscards, founders of the Norman dynasty in Naples.
The Count of Conversano was the most powerful lord in Lower Apulia. His possessions extended along the shores of the Adriatic, from Otranto to Bari. His castle was situated on an eminence, amid olive groves, and was replete with all those means for rendering life pleasant which the feudal system brought into existence. Curthose thought Conversano a terrestrial paradise, and was delighted with his host's fine hounds, choice hawks, and mettled steeds; but, above all, he was delighted, charmed, and fascinated with his host's daughter, Sybil, who was still in her teens, and as beautiful as she was young.
It could not be concealed that Curthose was verging on fifty, and that Sybil was just seventeen. But that was no conclusive objection to a match. In fact, such fame as that of a Crusader, and such rank as Duke of Normandy, were strong recommendations; so, when Curthose told his enamoured tale, Sybil smiled on her lover; and, ere long, the daughter of the Count of Conversano was led to the altar, and became Duchess of Normandy.
Even after his marriage Curthose found himself too comfortable to move. Perhaps he was averse to change the splendour of Conversano for the irksome poverty of Rouen. At all events he lingered in the scene of his courtship, and among the olive groves on the shores of the Adriatic wasted months, which, if judiciously spent, might have secured him a duchy and assured him a crown.
Among the ministers who enjoyed the favour of Rufus, and ministered to his tyranny, none had rendered himself more odious to the people of England than Ralph Flambard, Bishop of Durham, known as "the fighting bishop," and celebrated as founder of the castle of Norham-on-Tweed. Immediately on taking possession of the throne, Henry caused Flambard to be arrested and imprisoned in the Tower. Flambard, however, contrived to escape; and, passing over to Normandy, he exerted his eloquence to persuade Curthose to invade England and seize the English crown.
