As the very name itself suggests, this kind of literary device finds its roots in biblical origins. This term refers to the practice of basing a plot happening or event and anticipating the results it will have on a faction of the Bible. It involves a random selection process wherein the biblical passage is chosen as a founding stone for basing the outcome of the writing. In an overall context, not limited to just literature, bibliomancy refers to foretelling the future by turning to random portions of the Bible for guidance.
The Vedas serve as a tool for bibliomancy to the Hindus while Muslims rely on the Koran.
