Sacrifices were offered to these spirits by the Emperor on the marble altar of the Temple of Heaven, and by the high officials throughout the provinces. Of the twenty-eight the following are regarded as propitious—namely, the Horned, Room, Tail, Sieve, Bushel, House, Wall, Mound, Stomach, End, Bristling, Well, Drawn-bow, and Revolving Constellations; the Neck, Bottom, Heart, Cow, Female, Empty, Danger, Astride, Cock, Mixed, Demon, Willow, Star, Wing, are unpropitious.

The twenty-eight constellations seem to have become the abodes of gods as a result of the defeat of a Taoist Patriarch T’ung-t’ien Chiao-chu, who had espoused the cause of the tyrant Chou, when he and all his followers were slaughtered by the heavenly hosts in the terrible catastrophe known as the Battle of the Ten Thousand Immortals. Chiang Tzŭ-ya as a reward conferred on Page 192them the appanage of the twenty-eight constellations. The five planets, Venus, Jupiter, Mercury, Mars, and Saturn, are also the abodes of stellar divinities, called the White, Green, Black, Red, and Yellow Rulers respectively. Stars good and bad are all likewise inhabited by gods or demons.
