Michael Scott. Delphi: A History of the Center of the Ancient World.

Delphi, a renowned UNESCO World Heritage Site, emerges as a pivotal cultural and religious center in the ancient Greco-Roman world. The site's significance stems from its association with the oracle of Apollo and the omphalos, a symbol marking Delphi as the 'center of the world.' Archaeological exploration has revealed that Delphi attracted visitors from diverse backgrounds, who sought guidance from the Pythia, the priestess who delivered ambiguous prophecies often misinterpreted. Notable examples include King Croesus's disastrous misreading of an oracle's advice. The site flourished with dedications and architectural marvels until its decline in the 7th century due to plagues and invasions. Modern archaeological investigations, particularly by French, German, and Greek teams since the 19th century, have uncovered extensive layers of history, making Delphi one of the most thoroughly researched ancient sites.
