Robert E. Howard,
Blood of the Gods
(1935)
“ The Djinn of the Caves THE CAVES of EL KHOUR pit the sheer eastern walls of a gaunt hill-range that rises like a stony backbone out of a waste of rocky plains. There is only one spring in the hills; it rises in a cave high up in the wall and curls down the steep rocky slope, a slender thread of silver, to empty into a broad shallow pool below. The sun was hanging like a blood-red ball above the western desert when Francis Xavier Gordon halted near this pool and scanned the rows of gaping cave-mouths with blood-shot eyes. ”
