Pythia was famous oracles of Delphi. Kings and men traveled from all over the Mediterranean to hear her prophesies. These prophesies were often cryptic. One of her famous ones during the Persian invasion of 480BC she said that Athens would be safe behind the wall of wood. Some thought this meant the walls around Athens and some thought this meant Athens' navy. The Greeks believed that the oracle talked directly to the god Apollo. She was able to communicate with him by breathing in toxic fumes from a cave.
