一直以来，西方的文艺作品经常引用橄榄树作为荣誉﹑和平﹑希望﹑健康﹑财富等的象征。1896年，第一届现代奥运会在希腊举行，冠军奖牌雕有希腊女神雅典娜像，手持由橄榄叶织成的花冠，以象征胜利。2004年，雅典奥运会火炬的外形是卷起的橄榄叶，像是向上喷发的烈火，表达了促进各国人民沟通的愿望。橄榄树，别名齐墩果，它们的存活能力强吗？它们的果实又有什么用呢？
The photo shows an olive tree specimen design on the gate to the Church of All Nations， believed to be about 900 years old. Because olive trees have no annual growth rings， determining a particular tree’s age can be challenging.
However， a study carried out by the National Research Council of Italy has shown， by carbon dating methodology， that trunks of a few trees in the Garden of Gethsemane， Israel （behind the rock walls of the Church of All Nations） are around 900 years old. Roots of these trees may be even older.
Olive trees tolerate harsh growing conditions and can even renew its canopy following a fire. Its fruit was once an important source of food for local populations and its oil has long been used for lighting， as an ointment and as an important ingredient in soap production.
