Early in the 18th century, the Emperor Shi-tsung issued a proclamation against rain-conjuring, addressed to the Eight Banners of Mongolia. “If,” indignantly observes the Emperor, “if I, offering prayers in sincerity, have yet cause to fear that it may please heaven to leave MY prayer unanswered, it is truly intolerable that mere common people wishing for rain should of their own fancy set up altars of earth; and bring together a rabble of Hoshang (Buddhist Bonzes) and Taossi to conjure the spirits to gratify their wishes.” The belief in the efficacy of weather-conjuring prevailed all over Europe. In the _Cento Novelle Antiche_, certain necromancers gave specimens of their skill before the Emperor Frederic Barbarossa; and the weather began to be overcast; and lo, of a sudden rain fell with continued thunders and lightnings, as if the world were come to an end, and hailstones of the size and appearance of steel caps.

During the three months of every year that the Emperor resides at that place, if it should happen to be bad weather, there are enchanters and astrologers in his train, who are such adepts in necromancy and diabolic arts, that they are able to prevent any cloud or storm from passing over the spot on which the Emperor’s Palace stands. The sorcerers who do this are called Tebet and Kesimar, which are the names of two nations of idolaters. Whatever they do in this way is by the help of the Devil, but they make those people believe that it is compassed by dint of their own sanctity and the help of GOD....
