On the 11th February 1503 Henry VII. had lost his queen, Elizabeth of York, who died in the Tower of London, a week after giving birth to her seventh child. She had been a good and submissive wife to Henry, whose claim to the throne she had strengthened by her own greater right. The bereaved husband retired 'heavy and dolorous' to a solitary place to pass his sorrow, but before many weeks were over he and his crony De Puebla put their heads together and agreed that the king must marry again. Amongst other alliances the widowed Queen of Naples was suggested, but the lady decidedly objected to the marriage. In November 1504 Queen Isabella of Castile died, and the crown descended to her weak-minded daughter Joanna. A struggle was seen to be impending for the regency, and Henry was courted by both sides in the dispute. He had taken as his motto 'Qui je défends est maître,' and both Ferdinand, King of Spain, and the Emperor Maximilian were anxious to win him to their side. Margaret was secretly offered to Henry as a bride by Philip and Maximilian, and a close alliance between them proposed. Margaret, with her large dowries from Castile and Savoy, was now one of the richest princesses in Europe. Whilst Ferdinand was trying to ingratiate himself with Henry, it was clear to the astute King of England that he had now more to hope for from Philip and Maximilian, who were friendly with France, than from Ferdinand.[23] [23] Martin Hume, _Queens of Old Spain_. Early in August 1505 De Puebla went to Richmond to see the Princess of Wales, and as he entered the palace one of the household told him that an ambassador had just arrived from the Archduke Philip, King of Castile, and was waiting for an audience. De Puebla at once conveyed the news to Katharine, and served as interpreter between the ambassador and the princess. After delivering greetings from the Emperor Maximilian, the Archduke Philip, and the Duchess of Savoy, the ambassador said his mission was a secret one to settle with the King of England about his marriage with the Duchess of Savoy, of whom he had brought two portraits. The Princess of Wales wished to see them, and the ambassador went to fetch them. One was painted on wood, the other on canvas. The princess was of opinion that Michel would have made better portraits. She asked the ambassador when the King-Archduke and the Queen-Archduchess were to leave for Spain. The ambassador replied as soon as possible, but that he had come to consult the King of England as to all arrangements.'[24] [24] It would be interesting to know what became of these pictures. The portrait of Margaret, now at Hampton Court Palace, may have been one of them, as in it she is represented wearing a widow's dress, and the painting is so indifferent that it may well have called forth Katharine's criticism.
