Found in A.E. Waite's Occult Sciences (1891) between Belomancy and Capnomancy (divination by smoke) this method of detecting witches and sorcerers and also using a Bible for prediction etc., Belomancy, by the way, is divination by arrows...
Occasionally the forms of divination exceeded the bounds of superstition, and passed into the region of frantic madness. There was a short way the sorcerers which was probably the most potent discoverer of witchcraft which any ingenuity could devise. A large Bible was deposited on one side of a pair of weighing scales. The person suspected of magical practices was set on the opposite side. If he outweighed the Bible he was innocent; in the other case, he was held guilty. In the days of this mystical weighing and measuring, the scales may be truly said to have fallen from the eyes of a bewizarded generation, and to have revealed " sorcery and enchantment everywhere."
Bibliomancy, however, included a more harmless practice, and one of an exceedingly simple character. This was the opening of the Bible with a golden pin, and drawing an omen from the first passage which presented itself. Books like the Scriptures, the "Following of Christ," and similar works, abound in suggestive and pertinent passages which all men may apply to temporal affairs, but declares that he had recourse to it in all cases of spiritual difficulty. The appeal to chance is, however, essentially superstitious.
