Olives were central to nearly every aspect of life in ancient Greece, from athletics and medicine to religion, law, and international trade. The olive tree held such importance that destroying certain protected trees in Athens was punishable by death. While we tend to think of olives mainly as food, the ancient Greeks used them for far more than eating.
A Gift From the Gods
The olive tree’s significance in Greece began with mythology. According to Greek myth, the goddess Athena gifted the olive tree to Athens as a symbol of peace, wisdom, and prosperity. This origin story made the tree sacred, and specific olive trees in Athens, known as “moriai,” were considered state property under religious protection. These weren’t just symbols. Harming a moriai tree was a capital offense.
The lawmaker Solon, one of Athens’ most influential reformers, enacted a decree limiting the felling of olive trees to no more than two per year in any single grove. This kind of legal protection for a single plant species was extraordinary in the ancient world and signals just how economically and spiritually vital olives were to Athenian society.
Fuel for Athletes
One of the most distinctive uses of olive oil in ancient Greece was in athletics. Beginning around the eighth century BC, wrestlers and other combat athletes rubbed their bodies with oil before training and competition. This wasn’t vanity. The oil served multiple practical purposes: it reduced skin abrasion during grappling, kept dirt from packing into pores, and made it easier for an athlete to slip out of dangerous holds like neck traps. Athenian sponsors of sporting events provided free oil to all sport facilities so athletes could use it without cost.
The warming and flexibility benefits were well understood. Hippocrates wrote that rubbing with oil raised body temperature and made muscles more limber, helping prevent injuries. He distinguished between exercising in oil versus exercising in dust, noting that “oil is warm” and “rubbing with oil and water softens the body, and prevents it becoming over-heated.” The philosopher Philostratus even published specific instructions on how trainers should apply oil, recommending moderate amounts with special attention to the lower body.
Other theories about the practice existed too. Some believed the oil coating protected against sun exposure and prevented dehydration by reducing the loss of body fluids during exercise. Others thought it simply produced a glistening body that was aesthetically pleasing, which mattered in a culture that celebrated the athletic physique. The Roman writer Pliny added that oil protected against cold. In reality, it likely did all of these things at once.
Medicine and Healing
Greek physicians incorporated olive oil into their treatments regularly. Hippocrates referenced olive oil for warming the body, improving flexibility, and preparing muscles for physical activity, essentially prescribing it as a preventive therapy against sports injuries. Massage with olive oil was used to reduce muscle fatigue and remove the buildup of lactic acid after exertion. This made it one of the earliest documented recovery tools in sports medicine.
Beyond athletics, olive oil served as a base for various remedies and was applied to wounds, skin conditions, and sore joints. Its role in Greek medicine was broad enough that it appeared throughout the Hippocratic writings as a standard therapeutic ingredient rather than a specialty item.
A Cornerstone of Trade
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 closely resembled how fine wine is marketed today, with emphasis on place of origin and variety. Greek city-states built real wealth on olive cultivation, and the oil flowed to trading partners throughout the ancient world.
The value of olive oil is perhaps best illustrated by athletic prizes. Victorious boxers at the Panathenaic games in Athens received 60 amphorae of Athenian olive oil, roughly equal to 600 gallons. Each standard Panathenaic amphora held about 39 liters. This was not a token reward. It was a fortune in liquid form, easily converted to cash through trade. The amphorae themselves were decorated with distinctive imagery and became iconic objects, many of which survive in museums today.
Cooking, Lighting, and Daily Life
Olive oil was the primary cooking fat in the Greek diet, used for frying, dressing, and preserving food. Table olives, cured in brine or salt, were a dietary staple across social classes. But olive oil also powered daily life in a more literal sense: it fueled the oil lamps that lit Greek homes, workshops, and temples after dark. In an era before candles were widespread, a reliable supply of lamp oil was a household necessity, not a luxury.
The wood of the olive tree was valued for its exceptional density and durability. It was carved into kitchen utensils, serving pieces, and tools meant to withstand heavy daily use. In Homer’s Odyssey, Odysseus famously built his marriage bed around a living olive tree, a literary detail that reflected the wood’s real reputation for strength and permanence.
Ritual and Ceremony
Olive oil and olive branches appeared throughout Greek religious life. Oil was poured as a libation offering to the gods, used to anoint the dead before burial, and burned in temple lamps as a sacred light. Olive wreaths crowned victors at the Olympic Games, where the prize was glory rather than money, and the wreath’s material carried the weight of Athena’s blessing.
The connection between olives and Greek identity ran so deep that the olive tree on the Acropolis, said to be Athena’s original gift, was tended and revered for centuries. When the Persians burned Athens in 480 BC, ancient sources recorded that the sacred olive tree sprouted new growth almost immediately, a sign the Greeks interpreted as divine reassurance that their city would survive.
