Deep silence and sepulchral gloom suddenly succeeded to the joyous chants and prodigious radiance of the Basilica above. Cut in the rock, the crypt formed two narrow passages, parted by a massive block of stone which upheld the nave, and conducting to a subterranean chapel under the apse, where some little lamps remained burning both day and night. A dim forest of pillars rose up there, a mystic terror reigned in that semi-obscurity where the mystery ever quivered. The chapel walls remained bare, like the very stones of the tomb, in which all men must some day sleep the last sleep. And along the passages, against their sides, covered from top to bottom with marble votive offerings, you only saw a double row of confessionals; for it was here, in the lifeless tranquillity of the bowels of the earth, that sins were confessed; and there were priests, speaking all languages, to absolve the sinners who came thither from the four corners of the world. At that hour, however, when the multitude was thronging the Basilica above, the crypt had become quite deserted. Not a soul, save Pierre's, throbbed there ever so faintly; and he, amidst that deep silence, that darkness, that coolness of the grave, fell upon his knees. It was not, however, through any need of prayer and worship, but because his whole being was giving way beneath his crushing mental torment. He felt a torturing longing to be able to see clearly within himself. Ah! why could he not plunge even more deeply into the heart of things, reflect, understand, and at last calm himself.
