The Olive (Olea europaea) is a species of a small tree in the family Oleaceae, native to the coastal areas of the eastern Mediterranean Basin (the adjoining coastal areas of southeastern Europe, western Asia and northern Africa) as well as northern Iran at the south end of the Caspian Sea. Its fruit, the olive, is of major agricultural importance in the Mediterranean region as the source of olive oil. The tree and its fruit give its name to the plant family, which also includes species such as lilacs, jasmine, forsythia and the true ash trees (Fraxinus). The word 'oil' in many languages ultimately derives from the name of the tree and its fruit, including the English word oil. The olive tree is an evergreen tree or shrub native to the Mediterranean, Asia and parts of Africa. It is short and squat, and rarely exceeds 8–15 meters in height. The silvery green leaves are oblong in shape, measuring 4–10 cm long and 1–3 cm wide. The trunk is typically gnarled and twisted. The small white flo
...wers, with ten-cleft calyx and corolla, two stamens and bifid stigma, are borne generally on the last year's wood, in racemes springing from the axils of the leaves. The fruit is a small drupe 1–2.5 cm long, thinner-fleshed and smaller in wild plants than in orchard cultivars. Olives are harvested at the green stage or left to ripen to a rich purple colour (black olive). Canned black olives may contain chemicals that turn them black artificially. The olive is one of the plants most cited in recorded literature. In Homer's Odyssey, Odysseus crawls beneath two shoots of olive that grow from a single stock,[1] and in the Iliad,(XVII.53ff) is a metaphoric description of a lone olive tree in the mountains, by a spring; the Greeks observed that the olive rarely thrives at a distance from the sea, which in Greece invariably means up mountain slopes. Greek myth attributed to the primordial culture-hero Aristaeus the understanding of olive husbandry, along with cheese-making and bee-keeping.[2] Olive was one of the woods used to fashion the most primitive Greek cult figures, called xoana, referring to their wooden material; they were reverently preserved for centuries.[3] It was purely a matter of local pride that the Athenians claimed that the olive grew first in Athens.[4] In an archaic Athenian foundation myth, Athena won the patronship of Attica from Poseidon with the gift of the olive. Though, according to the 4th-century BC father of botany, Theophrastus, olive trees ordinarily attained an age of about 200 years,[5] he mentions that the very olive tree of Athena still grew on the Acropolis; it was still to be seen there in the second century AD;[6] and when Pausanias was shown it, ca 170 AD, he reported "Legend also says that when the Persians fired Athens the olive was burnt down, but on the very day it was burnt it grew again to the height of two cubits;"[7] indeed, the olive suckers readily from the stump, and the great age of some existing olive trees shows that it was perfectly possible that the olive tree of the Acropolis dated to the Bronze Age. The olive was sacred to Athena and appeared on the Athenian coinage. The Roman poet Horace mentions it in reference to his own diet, which he describes as very simple: "As for me, olives, endives, and smooth mallows provide sustenance."[8] Lord Monboddo comments on the olive in 1779 as one of the foods preferred by the ancients and as one of the most perfect foods.[9]. The leafy branches of the olive tree - the olive leaf as a symbol of abundance, glory and peace - were used to crown the victors of friendly games and bloody wars. As emblems of benediction and purification, they were also ritually offered to deities and powerful figures; some were even found in Tutankhamen's tomb. Olive oil has long been considered sacred; it was used to anoint kings and athletes in ancient Greece. It was burnt in the sacred lamps of temples as well as being the "eternal flame" of the original Olympic Games. Victors in these games were crowned with its leaves. Today, it is still used in many religious ceremonies. Over the years, the olive has been the symbol of peace, wisdom, glory, fertility, power and pureness. The olive tree and olives are mentioned over 30 times in the Bible, in both the New and Old Testaments. It is one of the first plants mentioned in the Bible, and one of the most significant. For example, it was an olive branch that a dove brought back to Noah to demonstrate that the flood was over. The Mount of Olives east of Jerusalem is mentioned several times. The Allegory of the Olive Tree in chapter 5 of the [Book of Jacob]] in the Book of Mormon, refers to the scattering and gathering of Israel. It compares the Israelites and gentiles to tame and wild olive trees. The olive tree itself, as well as olive oil and olives, play an important role in the Bible.[10] The olive is praised in the Quran as a precious fruit. The olive tree and olive oil are also mentioned seven times in the Quran. In Chapter 24 Al-Nur: "Allah is the Light of the heavens and the earth. The metaphor of His Light is that of a niche in which is a lamp, the lamp inside a glass, the glass like a brilliant star, lit from a blessed tree, an olive, neither of the east nor of the west, its oil all but giving off light even if no fire touches it. Light upon Light. Allah guides to His Light whoever He wills and Allah makes metaphors for mankind and Allah has knowledge of all things." (Quran, 24:35). Olive tree and olive oil health benefits have been propounded in Prophetic medicine. The Prophet Mohamed is reported to have said: "Take oil of olive and massage with it - it is a blessed tree" (Sunan al-Darimi, 69:103). The olive tree seems to have been native in the Mediterranean region and Western Asia and spread to nearby countries from there. It is estimated the cultivation of olive trees began more than 7000 years ago. As far back as 3000 BC, olives were grown commercially in Crete; they may have been the source of the wealth of the Minoan Civilization.[11] The ancient Greeks used to smear olive oil on their bodies and hair as a matter of grooming and good health. Theophrastus, in On the Nature of Plants, does not give as systematic and detailed an account of olive husbandry as he does of the vine, but he makes clear (in 1.16.10) that the cultivated olive must be vegetatively propagated; indeed, the pits give rise to thorny, wild-type olives, spread far and wide by birds. Theophrastus reports how the bearing olive can be grafted on the wild olive, for which the Greeks had a separate name, kotinos.[12] After the 16th century, the Europeans brought the olive to the New World, and its cultivation began in Mexico, Peru, Chile and Argentina, and then in the 18th century in California. It is estimated that there are about 800 million olive trees in the world today, and the vast majority of these are found in Mediterranean countries. Olive trees are very hardy, drought-, disease- and fire-resistant, and can live for very long. Its root system is very robust and capable of regenerating the tree even if the above-ground structure is destroyed. The older an olive tree is, the broader and gnarlier its trunk appears. Many olive trees in the groves around the Mediterranean are said to be several centuries old, and in some cases this has been verified scientifically. Pliny the Elder told of a sacred Greek olive tree that was 1600 years old. Several trees in the Garden of Gethsemane (from the Hebrew words "gat shemanim" or olive press) in Jerusalem are claimed to date back to the time of Jesus.[13] Some Italian olive trees are believed to date back to Roman times, although identifying progenitor trees in ancient sources is difficult. One olive tree in Bar, Montenegro, is claimed to be over 2000 years old [14]. The age of an olive tree in Crete, claimed to be over 2,000 years old, has been determined on the basis of tree ring analysis.[15] Another well-known olive tree on the island of Brijuni (Brioni), Istria in Croatia, has been calculated to be about 1,600 years old. It still gives fruit (about 30 kg per year), which is made into top quality olive oil.[16] An olive tree in west Athens, named "Plato's Olive Tree", was rumored to be a remnant of the grove within which Plato's Academy was situated, which would date it to approximately 2,400 years ago. The tree was a cavernous trunk from which a few branches were still sprouting in 1975, when a traffic accident caused a bus to fall on and uproot it. Since then the trunk is preserved and displayed in the nearby Agricultural University of Athens. A supposedly even older tree, called the "Peisistratos Tree", is located by the banks of the Cephisus River, in the municipality of Agioi Anargyroi, and is said to be a remnant of an olive grove planted by Athenian tyrant Peisistratos in the 6th century BC. According to a recent scientific survey, there are tens of ancient olive trees throughout Biblical Israel, 1600-2000 years old,[17] from even before the rise of Islam. Specifically, two giant olive trees in the Arab town of Arraba and five trees in Deir Hanna, both in Galilee region, have been determined to be over 3000 years old. All seven trees continue to produce olives.[17] A tree located in Santu Baltolu di Carana in Sardinia, Italy, named with respect as the Ozzastru by the inhabitants of the region, is claimed to be 3000 to 4000 years old according to different studies. In the same natural garden, a few other millenary trees can be admired. The olive tree has been cultivated for olive oil, fine wood, olive leaf, and the olive fruit. The earliest evidence for the domestication of olives comes from the Chalcolithic Period archaeological site of Teleilat Ghassul in what is today modern Jordan. Farmers in ancient times believed olive trees would not grow well if planted more than a short distance from the sea; Theophrastus gives 300 stadia (55.6 km) as the limit. Modern experience does not always confirm this, and, though showing a preference for the coast, it has long been grown further inland in some areas with suitable climates, particularly in the southwestern Mediterranean (Iberia, northwest Africa) where winters are mild.
