Olive oil: A treasure trove of taste

Its branches crowned victors and its oil anointed kings, lit lamps, healed wounds and dressed the dead. Long before it was a kitchen staple, olive oil was treasure — and the reasons the ancients prized it explain why a good bottle still matters today.

There is a reason olive oil turns up in almost every old story of the Mediterranean. For thousands of years it was not merely food but wealth, medicine, cosmetic, fuel and sacrament all at once — a single pressed fruit doing the work of a modern pharmacy, hardware store and bank. Understanding why the ancient world treated it as liquid gold is the shortest route to understanding why a genuinely good oil is still worth seeking out, and why so much of what fills supermarket shelves is a pale shadow of the real thing.

Wealth you could pour

In the ancient economies of Greece, the Levant and Rome, olive oil was capital. It stored well, travelled in sealed amphorae, and held its value across borders, so it functioned as a kind of edible currency — taxes were paid in it, temples stockpiled it, and fortunes were made shipping it. An olive grove was a slow, patient inheritance: a tree takes years to bear and generations to mature, so planting one was a bet on your grandchildren. That long horizon shaped whole cultures around the tree, and it is why the oldest working olive trees on earth are counted in centuries, not decades. See the oldest olive tree in the world.

Medicine, light and ritual

Before it was a salad dressing it was a salve. Ancient physicians used olive oil to clean wounds, carry herbal remedies and soothe skin, and athletes rubbed it on before competition and scraped it off after. It burned in the lamps that lit homes and temples, which is why a failed harvest meant darkness as much as hunger. And it was holy: kings and priests were anointed with it, the dead were prepared with it, and it fuelled the eternal flames of sanctuaries. When a substance lights your house, heals your body and consecrates your gods, you do not treat it casually — you guard it, grade it and pay for the best.

From liquid gold to supermarket staple

The modern era did something the ancients would have found astonishing: it made olive oil cheap and abundant. That is a genuine good — a food once reserved for the wealthy now dresses everyone’s salad. But abundance came at a cost to meaning. When oil was precious, its quality was jealously protected; now it is a commodity, and commodities get cut, blended and stretched. The ancient reverence has a practical modern lesson buried in it: the gap between a real, fresh, single-origin extra virgin and an anonymous blended bottle is as wide as it ever was. The ancients paid for the difference because they could taste it. So can you.

First cultivation	Eastern Mediterranean, roughly 6000–4000 BC
As currency	Traded in amphorae; taxes and wages paid in oil
As medicine	Wound care, ointment base, skin and athletic use
As light	Fuel for household and temple lamps
As sacrament	Anointing of kings and priests; funerary rites
Today	An everyday kitchen staple worldwide

What the history means for your kitchen

• Treat good oil as the finishing ingredient the ancients prized, not just frying fat — a raw drizzle is where quality shows.
• Buy for freshness and origin: a harvest date and a named region are the modern version of a guarded amphora.
• Remember oil is perishable — light, heat and age were its enemies then and now. Keep it cool and dark.
• The price gap between real and cut oil is old news; the ancients paid it knowingly. See the true cost of an olive.

Olive oil in history: common questions

How long have people made olive oil?

Roughly eight thousand years. The olive was domesticated in the eastern Mediterranean around 6000–4000 BC, and pressing for oil followed soon after.

Was olive oil really used as money?

In effect, yes. It stored and travelled well and held its value, so it was traded, taxed and stockpiled as a form of wealth across the ancient Mediterranean.

Why did the ancients anoint people with olive oil?

It was the most precious pure substance readily available — clean, fragrant and valuable — which made it fitting for consecrating kings and priests and for funerary rites.

Did olive oil really fuel lamps?

Yes. It was a primary lamp fuel for homes and temples, so the olive harvest lit the ancient world as well as fed it.

Does this history matter to how I buy oil today?

It does. The ancient reverence tracked real quality differences you can still taste. Buying fresh, named, single-origin oil is the modern echo of prizing the good stuff over the ordinary.
