Robert E. Howard,
The Hour of the Dragon — Chapter 22
(1935)
“ Down in the valley Amalric had stiffened in his saddle when he saw that wild horseman curvetting and caracoling on the slopes while he brandished that blood-stained serpent-banner. Then some instinct jerked his head about, toward the hill known as the King's Altar. And his lips parted. Every man in the valley saw it -- an arching shaft of dazzling light that towered up from the summit of the hill, showering golden fire. High above the hosts it burst in a blinding blaze that momentarily paled the sun. "That's not Xaltotun's signal!" roared the baron. "No!" shouted Tarascus. ”
