Frequently Asked Questions
What does the olive branch symbolize?
The olive branch is the most recognized symbol of peace in Western civilization — its origins trace to the ancient Greek story of Athena and Poseidon competing to give the city that would become Athens its most valuable gift. For a complete overview, see our Cultural & Historical guide.Poseidon struck the Acropolis rock and produced a spring of salt water (powerful but useless); Athena planted an olive tree (useful, enduring, peaceful). The city chose Athena's gift, named itself after her, and the olive branch became the symbol of Athena's peace, wisdom, and prosperity. In the story of the biblical flood, the dove returns to Noah's ark with an olive branch — the first sign of land, of the drought's end, of peace between God and humanity. This dual origin (Greek mythology and Judeo-Christian scripture) established the olive branch as the universal symbol of reconciliation, peace, and new beginnings.
The phrase "extend the olive branch" — meaning to make a peace offering — has been in continuous use for over 2,000 years, entering English through the Latin translation of Greek and biblical texts. The olive branch appears on the flags of the United Nations and the European Union (both post-WWII organizations founded explicitly to bring peace to a war-devastated continent), on state seals, military insignia, and diplomatic correspondence. This symbolic continuity — the same gesture and meaning across 2,500 years of recorded history — reflects the olive tree's actual role in Mediterranean life: the tree that ended enmity between communities that shared olive groves, that provided the oil that lit the lamps of temples and homes, that was the most valuable trade good of the ancient Mediterranean economy. The symbolic and the practical merged in olive oil to a degree unique in agricultural history.1
Olive Oil in Ancient Religion and Temple Worship
In ancient Mediterranean religions, olive oil was the primary sacred substance — the fuel for sacred fires, the annointing material for kings and priests, and the base for holy unguents used in temple worship. In ancient Greek religion, the oil from the sacred olive tree of Athena (the Ergane, the goddess's own tree on the Acropolis) was reserved exclusively for temple use — Athena's priests, not the general public, could Harvest it. Olive oil was poured on the heads of Olympic victors (the origin of the word "crown" from the kotinos, the sacred olive wreath), on the heads of athletes at the Pythian Games, and on the tombs of the dead as an offering to the gods for their passage. The oil of the goddess's tree was the most sacred substance in Athenian religious practice.
In the ancient Near East, olive oil was similarly sacred — the Hebrew Bible describes the holy annointing oil used to consecrate the Tabernacle and its vessels, and the priests and kings of Israel. This tradition (from the Book of Exodus) specified a particular blend of olive oil, myrrh, cinnamon, cane, and cassia — an expensive, aromatic unguent reserved exclusively for sacred use. The prohibition on using this holy oil for ordinary purposes ("It is most holy unto you") reflects the ancient understanding that olive oil was so valuable and sacred that some of it belonged to the divine, not the human, sphere. This sacred status of olive oil in Judaism influenced the early Christian understanding of the substance — the Greek words "christos" (Christ) and "messiah" both derive from the verb for annointing with oil, making olive oil the literal material of Christianity's founding symbol.1
Olive Oil as Medicine in Historical Medical Traditions
The ancient Mediterranean medical tradition treated olive oil as medicine before it was food — the Hippocratic Corpus (460–370 BCE) describes olive oil as a treatment for dozens of conditions: wounds (applied topically for its healing and antimicrobial properties), ear infections (warmed olive oil drops), skin conditions, joint pain, and digestive complaints. The humoral theory of ancient medicine — which classified all substances by their hot/cold and wet/dry properties — categorized olive oil as hot and moist, appropriate for treating conditions of cold and dryness (arthritis, dry skin, constipation). Olive oil was the primary base for ancient pharmaceutical preparations — suspending powdered herbs, extracting plant compounds, and providing the nutritional substrate for healing.
Galen, the Roman physician whose medical system dominated European medicine for 1,500 years, systematized the use of olive oil as a pharmaceutical base, specifying particular olive oil quality grades for different medical applications. The highest-quality fresh olive oil (presumably from recently harvested, carefully processed olives) was reserved for pharmaceutical use; lower grades were used for cooking; the lowest grade (the remains after multiple pressings) was used for fuel and lamp oil. This quality hierarchy reflects the ancient understanding that olive oil's therapeutic potency was concentrated in its freshest, most carefully produced form — a claim supported by modern understanding of polyphenol degradation in stored or poorly processed oil. The medical use of olive oil continued through the Islamic Golden Age (where Avicenna described olive oil treatments in detail in the Canon of Medicine) and into the medieval European monastic medicinal tradition.2
The Cultural Legacy of Olive Oil in Modern Mediterranean Life
The cultural significance of olive oil in Mediterranean societies has not diminished with modernization — it has transformed while remaining central. In Greece, Italy, Spain, and the Levant, the olive harvest remains a communal, familial event that brings extended families together at a specific time of year, recreating the ancient pattern of collective agricultural labor that characterized Mediterranean village life. The pressing of new oil in the autumn is celebrated with festivals (the "festa dell'olio" in Italy, the "kylina" olive harvest festivals in Greece) that are simultaneously cultural preservation events, agricultural showcases, and expressions of community identity. These festivals are not merely tourist events — they reflect a living cultural memory of a time when the olive harvest determined the economic and nutritional survival of the family through the winter.
The Mediterranean custom of offering bread and olive oil as the first thing served to a guest in a home — before the meal begins, before wine or other foods — is a direct survival of the ancient sacred status of olive oil. When a Mediterranean host breaks bread, dips it in olive oil, and offers it to a guest, the guest is being welcomed into the household with its most sacred substance. The phrase "breaking bread together" carries this weight of communal welcome across all Mediterranean cultures. In the modern world, where food has become industrial, anonymous, and commoditized, this gesture retains its ancient significance — the food that sustains life is being shared, and in its sharing, the guest is welcomed into the community. This cultural dimension of olive oil — inseparable from its nutritional value — is the reason Mediterranean dietary habits are so resistant to change and so central to the cultural identity of the region.2
