Two monarchs could scarcely be more dissimilar than were Francis and the Emperor Charles. "So great is the difference between these two princes," says the Venetian Giustiniano, "that, as her most serene majesty the Queen of Navarre, the king's sister, remarked to me when talking on the subject, one of the two must needs be created anew by God after the pattern of the other, before they could agree. For, whilst the most Christian king is reluctant to assume the burden of great thoughts or undertakings, and devotes himself much to the chase or to his own pleasures, the emperor never thinks of anything but business and aggrandizement; and, whereas the most Christian king is simple, open, and very liberal, and quite sufficiently inclined to defer to the judgment and counsel of others, the emperor is reserved, parsimonious, and obstinate in his opinions, governing by himself, rather than through any one else."[217] This diversity of temperament and disposition had ample scope for manifestation during the protracted wars waged by the two monarchs with each other. Fit representative of the race to which he belonged, Francis was bold, adventurous, and almost resistless in the impetuosity of a first assault. But he soon tired of his undertakings, and relinquished to the cooler and more calculating Charles the solid fruits of victory.[218] [Sidenote: Francis's religious convictions.] Of the possession of deep religious convictions I do not know that Francis has left any satisfactory evidence. That he was not strongly attached to the Roman church, that he thoroughly despised the ignorant monks, whose dissolute lives he well knew, that he had no extraordinary esteem for the Pope, all this is clear enough from many incidents of his life. It would even appear that, at one or two points, he might have been pleased to witness such a reformation of the church as could be effected without disturbing the existing order. To this he was the more inclined, that he found almost all the men distinguished for their learning arrayed on the side of the "new doctrines," as they were styled, while the pretorian legion of the papacy was headed by the opponents of letters. [Sidenote: His fear of innovation.]
