The olive tree was the symbol of wisdom and peace, the sacred tree of the ancient city of Athens. According to Greek mythology, Zeus decided that the city should be given to either Poseidon or Athena, depending on who would offer the most useful gift. Poseidon hit the ground with his trident and a spring of sea water appeared, while Athena hit the bare ground with her spear and sprouted an olive tree. People chose Athena's gift and the city got its name. At the ancient Olympics, winners are honored with a simple olive wreath cut with a golden wild olive knife. The history of olive oil has been identified with Greek history for over 4,000 years.
