Rhapsodomancy

Rhapsodomancy is an ancient form of divination performed by choosing through some method a specific passage or poem from which to ascertain information.

There were various methods for practicing rhapsodomancy. Sometimes, individuals would write several verses or sentences from a poet on multiple pieces of wood, paper, or similar material, shake them together in an urn, and pick one at random. Sometimes, they cast dice on a table that was covered with verses; the one on which the die landed was said to contain the prediction.
