The olive tree represents the emblem of peace in all ancient cultures and religions of the Mediterranean basin. The myth says that, disputing the possession of Attica, Neptune and Minerva ended up before the council of the gods, who decided to trust the region to the one who did the most valuable present. Neptune, striking with his trident into the rock, made a spring sprung, while Minerva gave birth to an olive tree, giving her the victory. Since that day the olive tree was sacred to the goddess and was a symbol of peace, since this divinity maintained the order and laws. Olive oil -from the Latin oleum and the Greek elaia- is a product that along with the pickling of olives for consumption, gives the tree a great economic importance. Introduced in Spain by Phoenicians and Greeks in ancient Roman times this region was one of the most important producers of olive oil of the empire. The bulky mass of commodities exported-the dump of Rome Monte Testaccio contains about forty million hispanic amphorae- it enriched whole family clans of the Hispanic aristocracy. The Arabs of the Middle Ages recovered for Spain after the fall of Rome, that condition of main oil exporter that it had in antiquity. Al-Andalus was actually the first producer of olive oil in the world, with regions like the Aljarafe of Seville, with olive groves forty miles long, from Seville to Niebla, by twelve wide. After the arrival of Europeans to America, the Spaniards introduced the olive tree on the continent by the year 1550, it is one example of Old World plants traveling to the New World.
