The olive tree appeared on earth after the re-warming of the last glaciers. Old archaeological excavations brought to the surface of the Greek land fossils of olive leaf of the Palaeolithic and Neolithic period in the area of Santorini at 37.000 BC and traces of pollen in the Sahara region of 12,000 BC Fossilized olive leaves from 50,000 BC have also been presented. Found in the walls of the Caldera in Santorini island and Nisyros island. These fossils are proof of the first appearance of the olive tree and of its evolutionary course in the Mediterranean area.
The pigeon, with an olive branch symbol, brings to Noah after the cataclysm the message that the cataclysm has ended and life has returned to earth! Tradition indicating the utmost importance of the olive tree in the life of the ancient world for the entire region of the Eastern Mediterranean.
According to mythology, the controversy between Poseidon and Athena on the name of the city of Kekropa (of Athens, as it was later called) led Poseidon with a strong hit with his trident to create a small lake while Athena planted the first cultivated olive tree on the barren rock that filled with olives. The Athenians chose the olive tree, they gave their city the name of the deity, and while they lacked water, they prospered because of the blessed fruit of the holy olive tree. From this first sacred olive tree the first Athenian olive groves were created. These trees called them Mories (from the molecule-piece) since they all came from transplants. The olive oil of these holy oils was given as a prize to the Panathinaio winners. The importance of the olive for Athens was so great that the Athenians in their coins depicted Athena with an olive wreath in her helmet and an amphora with olive oil or olive branch.
The first extractions of olive oil were made in the “Leneon” (ancient stone pigeon) in which there were placed two large rotating stones where the olives were pulped. The rotation of these stones was done manually and much later mechanically. After the pulp, the oil fell mixed with water from the threshing floor into a special trough. The separation was made from the top, as the water was in the bottom. The first oil was called "tears" and used as a medicine!
For the Greeks olive tree it is not only economic significance that defines the productive map of several regions from the Minoan years to today. . It is a symbol of longevity and stability. The symbol of toil, patience and endurance to hardships. It is above all the sacred tree, since its product carries the divine Grace to the baptized Christian. In Russian Orthodox baptism, too, in the sanctuary water of the baptism, oil is added to protect the baptized by magic and negative influences.
Another tradition says that Hercules, when he finished his labours of the Northern Balkans, brought from the land of Istron (Dunes) an olive branch which he planted in Olympia. That shows first of all that the Greeks came into contact with wild olive trees and not with simple olive trees and subsequently how the Oleaster stretched quite farther north than today. The existence of the wild olive trees both North and so far from the warm sea of the Aegean Sea, was impressive for the ancient Greeks.
With the branches of this wild olive tree, they wore the Olympians in Ancient Greece as a symbol of victory, wisdom, peace, prosperity, repentance and fertility. The athletes were polished with oil before the races because they believed that they would perform better and win the victory prize. In honor of this relationship of Hercules with the first olive tree, at the Roman period, existed on the island of Delos and a temple with a statue dedicated to (Hercules Olivarius). The olive tree is undoubtedly a symbol - the foundation of the Mediterranean cultures.
In this myth probably witnessed two events: Firstly that the domestication of olives was in Greece and by extension that domestication was by Greeks themselves.
