“At the height of his prosperity Ssu-chuan fell in love with a very beautiful girl, called Mei-hsi, who became his mistress.

“The Empress Chwang-Keang was as plain as Mei-hsi was beautiful, and in time the mistress prevailed upon her lord to plot his wife’s murder, so that Mei-hsi might be queen. Chwang-Keang was stabbed to death one evening in her garden.

“With her death begins the history of Seuen-H’sin.

“Simultaneous with the murder of the empress, one of the moons vanished from the sky. The Chinese legends say the spirit of the great ruler took refuge upon the satellite, which fled with her from sight of the earth. Modern astronomers say the satellite probably was shattered by an internal explosion.

“Now that the firm hand of Chwang-Keang was lifted from affairs of state, everything went wrong in China—until the country reverted virtually to savagery.

“At last Ssu-chuan aroused himself from his pleasures sufficiently to take alarm. He consulted his priests and seers, who assured him that heaven was angry because of the murder of Chwang-Keang. Never again, they said, would China know happiness or prosperity until the vanished moon returned, bringing the spirit of the dead empress to watch over the affairs of her beloved land. Upon her return, however, the glory of China would rise again, and the Son of Heaven would rule the world.

“Upon receiving these tidings, the legends relate, Ssu-chuan was consumed with pious zeal.

“Upon a lofty mountain behind the city he built the most magnificent temple in the world, and installed there a special priesthood to beseech heaven to restore the second moon. This priesthood was named the Seuen-H’sin, or Sect of the Two Moons. The worship of the Moon God was declared the state religion.

“Gradually the belief that the Seuen-H’sin was to restore the second moon—and that, when this happened, the Celestial Kingdom again would enjoy universal rule—became the fanatical faith of a fourth of China.

“But finally, in a fit of remorse, Ssu-chuan burnt himself alive in his palace.
