He was uneasy, however, to be so far distant from the emperor, with whom he must treat; and he expressed his desire (which was complied with) to be removed to Madrid, in hopes that a personal interview would operate in his favor, and that Charles, if not influenced by his ministers, might be found possessed of the same frankness of disposition by which he himself was distinguished.

He was soon convinced of his mistake.

Partly from want of exercise, partly from reflections on his present melancholy situation, he fell into a languishing illness; which begat apprehensions in Charles, lest the death of his captive should bereave him of all those advantages which he purposed to extort from him.

He then paid him a visit in the castle of Madrid; and as he approached the bed in which Francis lay, the sick monarch called to him, "You come, sir, to visit your prisoner." "No," replied the emperor, "I come to visit my brother and my friend, who shall soon obtain his liberty." He soothed his afflictions with many speeches of a like nature, which had so good an effect that the king daily recovered;[*] and thenceforth employed himself in concerting with the ministers of the emperor the terms of his treaty.
