His later voyage was more successful, so far as arriving at the scene of operations was concerned. He arrived at the headquarters of the Crusade which was in front of the besieged city of Damietta, and went on in his rapid and solitary fashion to seek the headquarters of the Saracens. He succeeded in obtaining an interview with the Sultan; and it was at that interview that he evidently offered, and as some say proceeded, to fling himself into the fire as a divine ordeal, defying the Moslem religious teachers to do the same. It is quite certain that he would have done so at a moment's notice. Indeed throwing himself into the fire was hardly more desperate, in any case, than throwing himself among the weapons and tools of torture of a horde of fanatical Mahomedans and asking them to renounce Mahomet. It is said further that the Mahomedan muftis showed some coldness towards the proposed competition, and that one of them quietly withdrew while it was under discussion; which would also appear credible. But for whatever reason Francis evidently returned as freely as he came. There may be something in the story of the individual impression produced on the Sultan, which the narrator represents as a sort of secret conversion. There may be something in the suggestion that the holy man was unconsciously protected among half-barbarous orientals by the halo of sanctity that is supposed in such places to surround an idiot. There is probably as much or more in the more generous explanation of that graceful though capricious courtesy and compassion which mingled with wilder things in the stately Soldans of the type and tradition of Saladin. Finally, there is perhaps something in the suggestion that the tale of St. Francis might be told as a sort of ironic tragedy and comedy called The Man Who Could Not Get Killed. Men liked him too much for himself to let him die for his faith; and the man was received instead of the message. But all these are only converging guesses at a great effort that is hard to judge, because it broke off short like the beginnings of a great bridge that might have united East and West, and remains one of the great might-have-beens of history.
