Dowager of Portugal; and his sons were to remain in Spain as hostages for his fulfilment of the terms. But from the first Francis intended to violate the treaty of Madrid, wherever possible; and early in 1527 a stately train of French nobles, headed by De Grammont, Bishop of Tarbes, came with a formal demand for the hand of young Mary Tudor for the already much-married Francis. Again the palace of Greenwich was a blaze of splendour for the third nuptials of the little princess; and the elaborate mummery that Henry loved was re-enacted.[39] On the journeys to and from their lodgings in Merchant Taylors' Hall, the Bishop of Tarbes and Viscount de Turenne heard nothing but muttered curses, saw nothing but frowning faces of the London people; for Mary was in the eyes of Henry's subjects the heiress of England, and they would have, said they, no Frenchman to reign over them when their own king should die.[40] Katharine took little part in the betrothal festivities, for she was a mere shadow now. Her little daughter was made to show off her accomplishments to the Frenchmen, speaking to them in French and Latin, playing on the harpsichord, and dancing with the Viscount de Turenne, whilst the poor Queen looked sadly on. Stiff with gems and cloth of gold, the girl, appearing, we are told, "like an angel," gravely played her part to her proud father's delight, and the Bishop of Tarbes took back with him to his master enthusiastic praises of this "pearl of the world," the backward little girl of eleven, who was destined, as Francis said, to be the "cornerstone of the new covenant" between France and England, either by her marriage with himself, or, failing that, with his second son, the Duke of Orleans, which in every respect would have been a most suitable match.
