She pleased his fancy, and was not more strait-laced than the duke was scrupulous; and Fulbert, the tanner, kept but little watch over his daughter.

Robert gave the son born to him in 1027 the name of his glorious ancestor, William Longsword, the son and successor of Rollo.

The child was reared, according to some, in his father's palace, "right honorably as if he had been born in wedlock," but, according to others, in the house of his grandfather, the tanner; and one of the neighboring burgesses, as he saw passing one of the principal Norman lords, William de Bellesme, surnamed "The Fierce Talvas," stopped him, ironically saying, "Come in, my lord, and admire your suzerain's son." The origin of young William was in every mouth, and gave occasion for familiar allusions more often insulting than flattering.

The epithet bastard was, so to speak, incorporated with his name; and we cannot be astonished that it lived in history, for, in the height of his power, he sometimes accepted it proudly, calling himself, in several of his charters, William the Bastard (Gulielmus Notlzus).

He showed himself to be none the less susceptible on this point when in 1048, during the siege of Alencon, the domain of the Lord de Bellesme, the inhabitants hung from their walls hides all raw and covered with dirt, which they shook when they caught sight of William, with cries of "Plenty of work for the tanner!" "By the glory of God," cried William, "they shall pay me dear for this insolent bra-very!" After an assault several of the besieged were taken prisoners; and he had their eyes pulled out, and their feet and hands cut off, and shot from his siege-machines these mutilated members over the walls of the city.
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.
