A few weeks later De Puebla tells King Ferdinand that Margaret had sent a very loving letter to King Henry the previous week, holding out hopes that her father would send a 'great personage' as ambassador to England with full powers to conclude all the treaties which her brother Philip had arranged, and if necessary to grant more favourable conditions. De Puebla states that when he asked King Henry what the treaties were about, the king replied 'they were very good treaties, and very advantageous to himself personally, and also to his kingdom, for, besides his own marriage with the Archduchess Margaret, an alliance had been concluded between the Archduke Charles and his daughter, Princess Mary, and all matters respecting commerce settled according to his wishes.' De Puebla wound up his letter by informing Ferdinand that King Henry was anxious to keep friends with the Emperor Maximilian, and not to break off negotiations with him, at any rate not without first consulting the King of Aragon. On December 4th Maximilian wrote to Margaret acknowledging her letters and the articles concluded between the Flemish and English ambassadors. He told her that the French king had complained to the Pope, King Ferdinand, and even to the Diet of Constance, that he (Maximilian) had broken his word in marrying Prince Charles to Princess Mary. In order to satisfy his honour the emperor requests that a clause should be inserted in the marriage treaty to the effect that the whole treaty should be null and void, and not even the penalty paid if the King of France declare himself ready, within one year, to marry his daughter Claude to Prince Charles. On the 21st of December 1507 two treaties were drawn up and dated Calais. One, a treaty of alliance between Henry VII., Maximilian and Prince Charles, was practically the same as the former treaty concluded between Henry and the Archduke Philip; and the other, concerning the marriage of the Archduke Charles with the Princess Mary, was between Henry VII., Maximilian, the Archduke Charles and the Archduchess Margaret, but was unsigned. In this treaty the Archduke Charles is to conclude the marriage with the Princess Mary, either in person or by proxy, before the following Easter. He is to contract the marriage by ambassadors sent to England for the purpose within forty days after he has completed his fourteenth year. The King of England is to send Princess Mary to the Archduke Charles within three months after the marriage shall have been contracted _per verba de præsenti_. The dowry to consist of 250,000 crowns. The Emperor Maximilian, the Archduchess Margaret, Charles de Croy, Henry, Count of Nassau, bind themselves to pay 250,000 crowns to King Henry if the Archduke refuses to contract the marriage. The King of England and his nobles bind themselves to pay an equal sum to Maximilian if Princess Mary refuses to fulfil the agreement. The treaty to be ratified by the contracting parties before
