BIBLIOMANCY (from the Gr. βιβλίον, a book, and μαντεία, prophecy), a form of divination (q.v.) by means of the Bible or other books. The method employed is to open the Bible haphazard and be guided by the first verse which catches the eye. Among the Greeks and Romans the practice was known under the name of sortes Homericae or sortes Virgilianae, the books consulted being those of Homer or Virgil.
