This excited such general curiosity that the sisters forgot both their real and imaginary dangers. Lorenzo proceeded to raise the grate, in which the nuns assisted him to the utmost of their strength. The attempt was accomplished with little difficulty. A deep abyss now presented itself before them, whose thick obscurity the eye strove in vain to pierce. The rays of the lamp were too feeble to be of much assistance. Nothing was discernible, save a flight of rough unshapen steps which sank into the yawning gulf and were soon lost in darkness. The groans were heard no more; but all believed them to have ascended from this cavern. As he bent over it, Lorenzo fancied that he distinguished something bright twinkling through the gloom. He gazed attentively upon the spot where it showed itself, and was convinced that he saw a small spark of light, now visible, now disappearing. He communicated this circumstance to the nuns: they also perceived the spark; but when he declared his intention to descend into the cave, they united to oppose his resolution. All their remonstrances could not prevail on him to alter it. None of them had courage enough to accompany him; neither could he think of depriving them of the lamp. Alone therefore, and in darkness, he prepared to pursue his design, while the nuns were contented to offer up prayers for his success and safety.
