Again the rumour that the final straw that broke the emperor's resolution was the duke's desire to take Savoy and Guelders from his hand alone, is suggestive. On the duke's part, this wish might indicate an attempt to separate a portion of territory from the empire in a way to deceive his contemporaries into thinking that his kingdom was an imperial fief, while, in reality, it was an independent realm, as he or his successors could declare at a convenient moment. But this seems at variance with his attested desire for electoral support. It was a curious tangle and never fully unravelled. Yet, considering the emperor's personal characteristics, his last action does not seem inexplicable. As his visitor showed the intensity of his will, Frederic became restive. Phlegmatic, obstinate, yet conscious of his own weakness, personal conflicts with a nature equally obstinate and much more vigorous were exceedingly unpleasant. The collision made him writhe uneasily and prefer to slip out of his embarrassment as quietly as he could. The proposed leave-taking was to be very magnificent, and the magnificence again was significant of Burgundian wealth. Whether the duke would surely keep his pledge of sharing that wealth with the archduke if the emperor went so far that he could not draw back, was a consideration that undoubtedly may have affected Frederic. Had Mary of Burgundy accompanied her father, had the wedding of the daughter and investiture of the new king been planned for the same day, had the promises been exchanged simultaneously, the leave-taking might have passed, indeed, as a third ceremonial in all stateliness. If Frederic doubted the surety of his bargain, it is not surprising. It was notorious how the duke had played fast and loose with his daughter's hand, withdrawing it from the grasp of a suitor as the greater advantages of another alliance were presented to him, or as the mere disadvantage of any marriage at all became unpleasantly near. Vigorous man of forty that he was, Charles had no personal desire to see a son-in-law, _in propria persona_, waiting for his shoes--a fact perfectly patent to the emperor, as it was to the rest of the world. The task of making the imperial adieux was entrusted to the imperial chamberlain, Ulrich von Montfort, who duly presented his master's formal excuses to the duke, on the morning of November 25th. "Important and urgent affairs had necessitated his presence elsewhere. The arrangement discussed between them was not broken but simply postponed until a more convenient occasion rendered its execution possible," etc.
