Bram Stoker,
The Lair of the White Worm — Chapter 18…
(1925)
“ Adam Salton felt that he would never be able to free his mind from the memory of those dreadful moments. The gloom which surrounded that horrible charnel pit, which seemed to go down to the very bowels of the earth, conveyed from far down the sights and sounds of the nethermost hell. The ghastly fate of the African as he sank down to his terrible doom, his black face growing grey with terror, his white eyeballs, now like veined bloodstone, rolling in the helpless extremity of fear. The mysterious green light was in itself a milieu of horror. ”
