The Three Cities, Lourdes Volume III by Émile Zola

WHEN Pierre dragged Marie in her box to the front of the Grotto, and placed her as near as possible to the railing, it was past midnight, and about a hundred persons were still there, some seated on the benches, but the greater number kneeling as though prostrated in prayer. The Grotto shone from afar, with its multitude of lighted tapers, similar to the illumination round a coffin, though all that you could distinguish was a star-like blaze, from the midst of which, with visionary whiteness, emerged the statue of the Virgin in its niche. The hanging foliage assumed an emerald sheen, the hundreds of crutches covering the vault resembled an inextricable network of dead wood on the point of reflowering.

And the darkness was rendered more dense by so great a brightness, the surroundings became lost in a deep shadow in which nothing, neither walls nor trees, remained; whilst all alone ascended the angry and continuous murmur of the Gave, rolling along beneath the gloomy, boundless sky, now heavy with a gathering storm.
