The Delphic Oracle was where, according to Greek tradition, Apollo would speak through his priestesses. This work explores the importance placed on consultations at Delphi by Athenians in the city's age of democracy. It demonstrates the extent to which concern to do the will of the gods affected Athenian politics, challenging the notion that Athenian democracy may be seen as a model for modern secular democratic constitutions. All the known consultations of the oracle by Athens in the period before 300 BC are examined, and descriptions of consultations found in Attic tragedy and comedy are discussed. This work provides a new account of how the Delphic oracle functioned and presents a thorough analysis of the relationship between the Athenians and the oracle, making it essential reading both for students of the oracle itself and of Athenian democracy.)
