In September of 1525, Francis fell gravely ill, and his sister,
Marguerite de Navarre, rode from Paris to join him in Spain.The Imperial doctors examining the king believed that his illness was caused by his sorrow at not being received by the Emperor, and urged Charles to visit him. Charles, against the advice of his Grand Chancellor,
Mercurino Gattinara, who argued that seeing Francis on his deathbed was an action motivated by mercenary concerns rather than by compassion, and was thus unworthy of the Emperor, consented; and Francis soon made a complete recovery.
[55] An attempt to escape, however, proved fruitless, and succeeded only in getting Marguerite sent back to France.
