of his reign that he secured for France that inestimable relic, the crown of thorns. [Sidenote: His superstition,] This peerless memento of our Saviour's passion he purchased in Constantinople for an immense sum. But France was doubly and enviably enriched; for the Abbey of St. Denys was in possession of another, known to be equally authentic! Besides the crown, he also secured the sponge that was dipped in vinegar; the lance of the Roman soldier; also the swaddling-clothes in which the Saviour had first lain in the manger; the rod of Moses; and part of the skull of John the Baptist. These treasures he deposited in the "Holy Chapel" of Paris. [Sidenote: and crusade.] Under the papal auspices, St. Louis determined on a crusade; and nothing, except what we have already mentioned, can better show his mental imbecility than his disregard of all suitable arrangements for it. He thought that, provided the troops could be made to lead a religious life, all would go well; that the Lord would fight his own battles, and that no provisions of a military or worldly kind were needed. In such a pious reliance on the support of God, he reached Egypt with his expedition in June, A.D. 1249. The ever-conspicuous valour of the French troops could maintain itself in the battle-field, but not against pestilence and famine. [Sidenote: Its total failure.] In March of the following year, as might have been foreseen, King Louis was the prisoner of the Sultan, and was only spared the indignity of being carried about as a public spectacle in the Mohammedan towns by a ransom, at first fixed at a million of Byzantines, but by the merciful Sultan voluntarily reduced one fifth. Still, for a time, Louis lingered in the East, apparently stupefied by considering how God could in this manner have abandoned a man who had come to his help. Never was there a crusade with a more shameful end.
