Olive oil touched nearly every part of daily life in ancient Greece. It was food, fuel, medicine, soap, sunscreen, perfume base, religious offering, and athletic equipment. It was also one of the most valuable trade commodities in the Mediterranean, with prize quantities worth years of a worker’s wages. Few substances in history have served so many purposes at once.
The Foundation of Greek Cooking
Olive oil was the primary fat in the ancient Greek diet, used so generously that food was described as literally “swimming” in oil. No meal was complete without bread, and olives and olive oil together supplied a major share of daily calories. The core diet revolved around olives, cereal grains, pulses, fruit, wild greens, and herbs, with only limited amounts of goat meat, milk, game, and fish.
In traditional Greek cuisine, olive oil appeared in almost every culinary practice. The cooking term “ladera” comes from “ladi,” the Greek word for oil, and describes vegetables cooked in generous amounts of olive oil with onions, garlic, and herbs. The foundational technique called “tsigarisma,” essentially sautéing, involved wilting onions and garlic in hot olive oil to build depth of flavor before adding other ingredients. This wasn’t a garnish or finishing touch. Olive oil was the medium through which nearly all cooking happened.
Fuel for Light
Before candles became common, oil lamps were the primary source of artificial light across the ancient world. Olive oil is believed to have been the main fuel used in Mediterranean lamps. These small clay or glass vessels held oil with a wick and were used both indoors and outdoors. Business owners, including innkeepers and barkeepers, lit their establishments and nearby streets with oil lamps. Glass lamps, which came later, held oil without seepage and projected light more efficiently, but the fuel source remained the same.
Athletic Training and Competition
Ancient Greek athletes coated their bodies in olive oil before training and competing, a practice so routine it defined the culture of the gymnasium. The oil served multiple practical purposes. It raised body temperature during warm-up and improved muscle flexibility. For wrestlers and fighters in the pankration, the slippery coating reduced skin abrasion, kept dirt from packing into pores, and made it far easier to escape painful joint locks and chokeholds. Some ancient writers noted that the oil protected against sun exposure and cold, and may have reduced dehydration during exercise. Others pointed out the aesthetic dimension: a glistening, oiled body was considered beautiful.
After exercise, athletes scraped their skin with a curved metal tool called a strigil. This removed the mixture of oil, sweat, and dust that accumulated during training. The combination of olive oil massage and scraping functioned as both hygiene and recovery. Ancient sources describe how deep friction massage with olive oil helped reduce muscle fatigue and was believed to prevent sports injuries by keeping the skin and muscles supple.
Medicine and Healing
Hippocrates reportedly called olive oil “the great healer,” and physicians in antiquity prescribed it for an impressive range of conditions: fevers, hair loss, nausea, ulcers, wounds, and even flatulence. Oil was applied externally to injuries and skin conditions and taken internally for digestive complaints. The medical writer Soranus described how midwives should anoint a newborn baby with lukewarm olive oil and clean its mouth with it before the first gentle wash with water. From the first moments of life, olive oil was considered essential for health.
Soap, Perfume, and Personal Care
In a world without soap as we know it, olive oil served as the primary cleansing agent for the body. Combined with scraping (using the same strigil athletes used), it lifted dirt and dead skin far more effectively than water alone. The Roman writer Pliny the Elder captured the idea neatly: “There are two liquids that are especially agreeable to the human body, wine inside and oil outside… but oil is an absolute necessity.”
Olive oil also formed the base of ancient perfumes. Producers steeped oil with fragrant substances like roses, iris, myrrh, or cinnamon to create scented oils that functioned as personal fragrance. This practice dates back to the Bronze Age: palace records show that perfume made from oil and coriander was produced and distributed within Mycenaean palaces, which must have carried a distinctive scent. By the Classical period, perfumed oils were widely made and used by wealthy men and women alike.
Religious Offerings and Ritual
Olive oil held deep religious significance. Mycenaean Bronze Age tablets from the palace of Pylos record the production of specially scented oil intended as offerings to the gods. Perfumed oil was used in Greco-Roman religious ceremonies both as libations (liquid offerings poured out during prayer) and for the ritual anointing of divine statues. The olive tree itself was sacred to Athena, and oil carried symbolic weight in purification rites and funerary practices. It connected the everyday and the divine in a way few other substances could.
A Currency of Its Own
Olive oil was one of ancient Greece’s most valuable exports. The highest quality oils were shipped across the Mediterranean in ceramic transport vessels called amphorae, and the trade resembled the modern wine industry, with buyers paying premiums based on place of origin and variety. More than 2,000 different olive cultivars exist in the Mediterranean basin today, and that diversity has roots stretching back millennia.
The Panathenaic Games in Athens illustrate just how valuable olive oil was. The winner of the boys’ 200-meter sprint received 500 gallons of olive oil. The men’s winner took home 1,000 gallons. Athletes typically resold their prize oil for roughly 12 drachmas per 10-gallon vessel. To put that in perspective, a skilled carpenter in Athens earned about 1 drachma per day, based on inscriptions excavated on the Acropolis. That means a single athletic victory could be worth up to three years of a carpenter’s wages, all paid in olive oil.
Olives were historically the most important crop in the region, and olive oil functioned almost like a liquid currency: universally needed, easily stored, and widely traded. Its economic importance shaped agricultural decisions, foreign trade relationships, and even the political power of olive-growing regions for centuries.
