In the meantime the Archduke Philip happened to fall into Henry’s hands (Jan., 1506). Whilst crossing the sea to claim the kingdom of Castile in right of his wife, he was driven by stress of weather into Weymouth. Henry was too shrewd a politician not to make the most of so lucky an event, and detained him in a species of honourable captivity, until Philip had promised him the hand of his sister Margaret with a large dower. This marriage alliance was destined never to be realised. Another scheme, however, was subsequently proposed and met with more success. This was a marriage of Henry’s own daughter with Philip’s son Charles, Prince of Castile. News of their engagement was conveyed to the mayor and aldermen of the City by a letter from the king himself (25 Dec., 1507), in which he expatiated on the benefits, political and commercial, likely to arise from the match.(1016) This letter was followed by another from the king, dated from Greenwich, the 23rd June following, in which the Corporation was informed that for the assurance of execution of the marriage treaty both parties had given pledges, and that the City of London was, among other cities and towns, included in letters obligatory to that effect, which letters he begged should be sealed without delay with the Common Seal of the City.(1017) And so, after the manner of the times, the boy of eight was married (by proxy) to the girl of twelve, amid great rejoicings in London (17 Dec., 1508).(1018) (M549) If Henry amassed wealth, it was not from any miserly motive. He well knew the value of the money, and that peace at home was never better secured than by a full treasury. He made, moreover, a princely use of his money, encouraging scholarship, music, and architecture, and dazzled the eyes of foreign ambassadors with the splendour of his receptions. That he had a fine taste in building no one can deny who has once seen the chapel of King’s College, Cambridge, or the chapel that bears his name at Westminster. (M550) Originally intended by Henry as a resting place for the remains of his uncle, Henry VI, the last mentioned edifice was diverted from its purposes and became the chantry as well as the tomb of Henry VII himself. Anxiety for his soul caused him to bind the Abbot of Westminster by heavy penalties to the due observance of his obit. These penalties were set out in six books or deeds, sealed with the Common Seal of the City of London, and formally delivered to the king by a deputation of the mayor and aldermen, who received in return a seventh book to remain in their custody. In 1504—the year that Pope Julius sanctioned the removal of the remains of Henry VI from Windsor to Westminster—the mayor and citizens formally sealed the "books" before the Master of the Rolls at the Guildhall. Two years later certain livery companies undertook to keep the king’s obit on the day that the mayor for the time being went to take his oath at the Exchequer.(1019) (M551)
