The long passage from exploiting wildfires to tending fires and finally kindling them at will. Sporadic traces go back about a million years; habitual use became common between about 400,000 and 300,000 years ago.
I hunted out and stored in fennel stalk the stolen source of fire that has proved a teacher to mortals in every art and a means to mighty ends.
—— Aeschylus (attrib.), Prometheus Bound 109–111, trans. H. W. Smyth (Loeb, 1926)
History
Control of fire covers three different things: exploiting natural fires, keeping and carrying fire at a camp, and making fire at will, and the archaeological record tells them apart with varying success. At Wonderwerk Cave in South Africa, Acheulean layers about a million years old contain bone and plant ash burned in place. At Gesher Benot Ya'aqov in Israel, about 790,000 years ago, burned seeds, wood and flint fragments cluster in a few spots that may mark hearths. Older traces in East Africa exist but are hard to separate from wildfire. Most researchers think habitual fire use became widespread in Western Asia and Europe only between about 400,000 and 300,000 years ago; Qesem Cave in Israel has a central hearth of about four square metres, used repeatedly around 300,000 years ago and ringed by traces of butchery and hide-working. Making fire is the hardest stage to catch. In 2025 a team reported heated sediments, fire-cracked flint handaxes and two pieces of pyrite, a mineral rare in the area, from Barnham in Suffolk, England, about 400,000 years old, and argued that someone had struck pyrite against flint to raise sparks. The previous earliest evidence was a set of Neanderthal strike-a-light tools in France, about 50,000 years old.

Open questionspartly uncertain
- Evidence from a million years ago can show only the use of fire, not the ability to make it.
- For earlier traces of burnt earth and burnt bone in East Africa, wildfire is hard to rule out.
- The fire-making interpretation of the Barnham site depends on the inference that the pyrite was brought in from elsewhere.
- The cooking hypothesis lacks contemporaneous archaeological evidence.
- The date at which habitual use of fire began varies by region.
- Whether Prometheus Bound was written by Aeschylus is disputed.
Why it matters
Fire mattered first as energy. Cooked food is easier to chew and digest, and Richard Wrangham's "cooking hypothesis" links the smaller teeth and guts and larger brains of Homo erectus, about 1.8 million years ago, to a cooked diet; but no evidence of habitual fire survives from that period, and the hypothesis remains contested. Less disputed is how fire reorganised time and space. The hearth extended the day into the night, gave a group a fixed centre and made cold winters survivable. Fire was also the first means of changing materials: heated stone flakes more predictably, birch bark distils into tar glue, and later clay became ceramic and ore became copper. Prometheus Bound calls fire "a teacher to mortals in every art"; in 1824 Sadi Carnot still titled his study of the efficiency of steam engines Reflections on the Motive Power of Fire, the founding text of thermodynamics.
