"'Once every hundred years, on the festival of St. John, the enchantment ceases to have thorough sway; I am permitted to go forth and post myself upon the bridge of the Darro, where you met me, waiting until some one shall arrive who may have power to break this magic spell. I have hitherto mounted guard there in vain. I walk as in a cloud, concealed from mortal sight. You are the first to accost me for now three hundred years. I behold the reason. I see on your finger the seal-ring of Solomon the Wise, which is proof against all enchantment. With you it remains to deliver me from this awful dungeon, or to leave me to keep guard here for another hundred years.' "The student listened to this tale in mute wonderment. He had heard many tales of treasures shut up under strong enchantment in the vaults of the Alhambra, but had treated them as fables. He now felt the value of the seal-ring, which had, in a manner, been given to him by St. Cyprian. Still, though armed by so potent a talisman, it was an awful thing to find himself _tête-à-tête_ in such a place with an enchanted soldier, who, according to the laws of nature, ought to have been quietly in his grave for nearly three centuries. "A personage of this kind, however, was quite out of the ordinary run, and not to be trifled with, and he assured him he might rely upon his friendship and good will to do everything in his power for his deliverance. "'I trust to a motive more powerful than friendship,' said the soldier. "He pointed to a ponderous iron coffer, secured by locks inscribed with Arabic characters. 'That coffer,' said he, 'contains countless treasure in gold and jewels and precious stones. Break the magic spell by which I am enthralled, and one half of this treasure shall be thine.' "'But how am I to do it?' "'The aid of a Christian priest and a Christian maid is necessary. The priest to exorcise the powers of darkness; the damsel to touch this chest with the seal of Solomon. This must be done at night. But have a care. This is solemn work, and not to be effected by the carnal-minded. The priest must be a _Cristiano viejo_, a model of sanctity; and must mortify the flesh before he comes here, by a rigorous fast of four-and-twenty hours: and as to the maiden, she must be above reproach, and proof against temptation. Linger not in finding such aid. In three days my furlough is at an end; if not delivered before midnight of the third, I shall have to mount guard for another century.' "'Fear not,' said the student, 'I have in my eye the very priest and damsel you describe; but how am I to regain admission to this tower?' "'The seal of Solomon will open the way for thee.'
