Delphi was an ancient Greek city in which the most important oracle of the ancient Greek world operated. The city is mentioned from Homeric times with the name Pythos. At the beginning of historical times it was one of the cities of ancient Fokida, but gradually the role of the city was strengthened and developed into a pan-Hellenic center and a sacred city of the ancient Greeks. It was also the center of Delphic Amphitryon. Delphi maintained its important position until the end of the 4th century AD, when the operation of the oracle was finally put to an end by decree of the emperor Theodosius AD. In the following centuries the city declined and was permanently abandoned during the Slavic invasions.
