But, whatever may have been the precocious virtues of Margaret at the age of fifteen, it is certain that when, by her brother's elevation to the throne, she was introduced to the foremost place at court, it was her remarkable qualities of heart, quite as much as her recognized mental abilities, that called forth universal admiration. Her personal appearance, it is true, was a favorite subject for the encomium of poets; but her portraits fail to justify their panegyrics, and convey no impression of beauty. The features are large, the nose as conspicuously long as her brother's; yet the sweetness of expression, upon which Marot is careful chiefly to dwell in one of his elegant poetical epistles, is not less noticeable.[223]
In the conduct of public affairs Margaret took no insignificant part. Francis was accustomed so uniformly to entrust his mother and sister with important state secrets, that to the powerful council thus firmly united by filial and fraternal ties the term "Trinity" was applied, not only by the courtiers, but by the royal family itself.[224] Foreign diplomatists extolled Margaret's intelligent statesmanship, and asserted that she was consulted on every occasion.[225] It is a substantial claim of Margaret to the respect of posterity, that the influence thus enjoyed was, apparently, never prostituted to the advancement of selfish ends, but constantly exerted in the interest of learning, humanity, and religious liberty.
Margaret was first married, in 1509, to the Duke of Alençon, a prince whose cowardice on the battle-field of Pavia (1525), where he commanded the French left wing, is said to have been the principal cause of the defeat and capture of his royal brother-in-law. He made good his own escape, only to die, at Lyons, of disease induced by exposure and aggravated by bitter mortification. The next two years were spent by Margaret in unremitting efforts to secure her brother's release. With this object in view she obtained from the emperor a safe-conduct enabling her to visit and console Francis in his imprisonment at Madrid, and endeavor to settle with his captor the terms of his ransom. But, while admiring her sisterly devotion, Charles showed little disposition to yield to her solicitations. In fact, he even issued an order to seize her person the moment the term of her safe-conduct should expire--a peril avoided by the duchess only by forced marches. As it was, she crossed the frontier, it is said, a single hour before the critical time. The motive of this signal breach of imperial courtesy was, doubtless, the well-founded belief that Margaret was bearing home to France a royal abdication in favor of the Dauphin.[226]
