Although Francis began to "despise those things he had formerly held dear," he was not altogether freed from the bonds of vanity, nor had he "thrown off the yoke of servitude"; for when restored to health he was full of ambitious projects to make a great career for himself in the world. The realisation of his dreams seemed indeed near, as it happened at this time that a noble knight of Assisi was preparing to join the army of Gauthier de Brienne, then fighting the battles of Pope Innocent III, in Apulia. Francis, "greedy of glory," determined to accompany the knight to the wars, and began to prepare for the journey with more than usual magnificence. He was all impatience to start, and his mind was full of the expedition when he had a dream which filled him with hope. In lieu of the bales of silk in his father's warehouse, stood saddles, shields, and lances, all marked with the red cross, and as he marvelled at the sight a voice told him those arms were intended for himself and his soldiers. Rising next morning full of ambitious plans after such an omen of good fortune, he mounted his charger and rode through the town bidding farewell to his friends. He smiled on all and seemed so light of heart that they pressed round asking what made him so merry. "I shall yet be a great prince," he answered, and he passed out of the Porta Nuova, where but a short while before he had stood looking down so sadly on the valley he was now to traverse as an armoured knight. At Spoleto he had a return of intermittent fever, and while chafing at the delay a voice called to him: "Francis, who can do the most good, the master or the servant?" "The master," answered Francis, not in the least astonished by the mysterious question. "Why then dost thou leave the master for the servant, and the prince for the follower? Return to thy country, there shalt thou be told what to do; for thou hast mistaken the meaning and wrongly interpreted the vision sent thee by God."
