Oracles in the ancient Greek world were the way in which the people of Greece could communicate with their gods. Gods couldn’t be communed with directly, so an oracle, who was often a woman, was the person that the gods spoke through, acting as the medium between the divine realm and the world of mortals.

The most important oracles of Greek antiquity were Pythia (priestess to Apollo at Delphi ), and the oracle of Dione and Zeus at Dodona in Epirus. Other oracles of Apollo were located at Didyma and Mallus on the coast of Anatolia, at Corinth and Bassae in the Peloponnese, and at the islands of Delos and Aegina in the Aegean Sea.
