Originally, the divination used to assess the guilt or innocence of a person accused of sorcery. The person was weighed against the great Bible in the Church and if the person weighed less than the bible they were deemed innocent. Today, bibliomancy refers to divination interpreting randomly chosen passages in books and is also called stichomancy. The most common form is opening a book to a random page to answer a question. The Bible is still the most frequently used book, although any book may be used. Using books by Virgil and Homer specifically is called stoichemancy. The variant of using a book of poetry is called rhapsodomancy.
Bibliomancy is the use of books in divination. The method of employing sacred books (especially specific words and verses) for 'magical medicine', for removing negative entities, or for divination is universal in all religions of the world.
