Jurgen by James Branch Cabell

So Jurgen abode in Leukê, and complied with the customs of that country; and what with one thing and another, he and Chloris made the time pass pleasantly enough, until the winter solstice was at hand. Now Pseudopolis, as has been said, was at war with Philistia: so it befell that at this season Leukê was invaded by an army of Philistines, led by their Queen Dolores, a woman who was wise but not entirely reliable. They came from the coast, a terrible army insanely clad in such garments as had been commanded by Ageus, a god of theirs; and chaunting psalms in honor of their god Vel-Tyno, who had inspired this crusade: thus they swept down upon Pseudopolis, and encamped before the city.

These Philistines fought in this campaign by casting before them a more horrible form of Greek fire, which consumed whatever was not gray-colored. For that color alone was now favored by their god Vel-Tyno. "And all other colors," his oracles had decreed, "are forevermore abominable, until I say otherwise."
