The history of the oracle and the sanctuary of Delphi is closely connected with the history not only of Greece but also of the entire world as it was known then. The oracle and its forecasting the future responses have played a decisive role both in the historical process and the events of the time such as the oracle to king Croesus, and in the establishment of the Greek colonies. Because of its wealth and strong influence it soon became the object of discord among the Greek cities and the most desired prey for all the -barbarian” nations and tribes and remained that way for over a thousand years. Walking among the ruins of a splendour long past one recalls the great moments of Greek history , its exalted moments and petty political competitions. The sanctuary is the true mirror of ancient Greek history, since it has directly or indirectly participated in all the events marking this glorious course.
