The origin of the olive tree is lost in time, coinciding and mingling with the expansion of the Mediterranean civilizations which for centuries governed the destiny of mankind and left their imprint on Western culture.
The cultivation of olives and the production of olive oil have deep roots in the history of Spain. The olive, a symbol of peace, and the tree which produces olives (olea europea) are known to have been cultivated around the Mediterranean about 6000 years ago. Its origin could be the eastern Mediterranean, but most probably it originated in Greece. Stone tablets found dating back to 2500 BC from the court of King Minos of Crete make reference to this plant.
The olive tree was brought to the Iberian Peninsula by the Phoenicians and the Greeks. Olive cultivation was expanded considerably by the Romans, who also improved the techniques of oil production. Olive oil from Hispania was highly regarded by the inhabitants of Old Rome, as well as by the rest of the Roman Empire, that considered it of superior quality.
Later, the Arabs continued perfecting the technique of olive oil production. The importance of the Arab influence is evident by the fact that the Spanish word for oil – aceite – comes from the Arabic – al-zat-, or olive juice.
