The Sortes Vergilianae (Virgilian Lots) is a form of divination by bibliomancy in which advice or predictions of the future are sought by interpreting passages from the works of the Roman poet Virgil. The use of Virgil for divination may date to as early as the second century AD, and is part of a wider tradition that associated the poet with magic. The system seems to have been modeled on the ancient Roman sortes as seen in the Sortes Homericae, and later the Sortes Sanctorum.
