text: what is the oracle of delphi and where is it located?   dating back to 1400 bc, the oracle of delphi was the most important shrine in all greece, and in theory all greeks respected its independence. built around a sacred spring, delphi was considered to be the omphalos - the center (literally navel) of the world.  people came from all over greece and beyond to have their questions about the future answered by the pythia, the priestess of apollo. and her answers, usually cryptic, could determine the course of everything from when a farmer planted his seedlings, to when an empire declared war.
