In the Greek world, there was no higher legal or religious authority than the Oracle of Apollo at Delphi. City-states and individuals from all over the Mediterranean would make the pilgrimage to Delphi to ask the god for guidance on matters of law, war, and justice. The Oracle's cryptic pronouncements could be used to justify new law codes, settle constitutional disputes, and sanction acts of war. This episode examines the unique role of the Delphic Oracle as a supreme court for the Greek world. We explore historical examples of lawgivers, like Lycurgus of Sparta and Solon of Athens, who sought the Oracle's sanction to give their laws divine authority. We look at how cities would consult the Oracle to determine how to purify themselves from the religious pollution of a murder. The god's word was a powerful tool for resolving otherwise intractable legal and political conflicts. The Oracle at Delphi acted as a stabilizing force in the fragmented world of the Greek city-states. It provided a shared, sacred authority that could legitimize laws and mediate disputes. It represents the ultimate fusion of law and religion in ancient Greece, a place where divine will was translated directly into legal principle.
