The olive tree (Olea europaea) is one of the oldest cultivated plants in human history. Native to the Mediterranean Basin, this resilient and revered tree has played a significant role in the lives of civilizations for thousands of years. Known for its longevity, the olive tree not only symbolizes peace and prosperity but also serves as a cornerstone of Mediterranean culture, diet, and economy.
Historical Significance
Olives have been cultivated for over 6,000 years, with their origins tracing back to ancient civilizations such as the Greeks, Romans, and Phoenicians. The olive tree was considered sacred in Greek mythology, symbolizing Athena's gift to humanity. Romans viewed olive oil as "liquid gold," a valuable commodity used for cooking, medicine, and even lighting lamps.
Archaeological evidence suggests that olives were first cultivated on the island of Crete around 2,500 BCE, spreading throughout the Mediterranean region. Today, this ancient crop continues to thrive, bridging history with modern agricultural practices.
