Sortes Homericae
The Sortes Homericae (Latin for "Homeric lots"), a type of divination by bibliomancy, involved drawing a random sentence or line from the works of Homer (usually the Iliad) to answer a question or to predict the future. In the Roman world it co-existed with the various forms of the sortes, such as the Sortes Virgilianae and their Christian successor the Sortes Sanctorum.
