Testing the Past by Doing It
Experimental archaeology turns speculation into hypothesis-testing: replicate the technology, run the process, compare the results with the archaeological record. If your reconstruction cannot actually work, it is not what happened.
The results are humbling and precise. Flint knapping shows that an Acheulean handaxe demands hours of skilled, forward-planned reduction — the maker held the finished shape in mind before the first strike. Replica firings reveal what kiln temperatures the pottery required. Experimental earthworks, deliberately built and then re-excavated after decades, show exactly how ditches silt and mounds slump — calibrating how archaeologists read every ditch section. And the Kon-Tiki and Polynesian voyaging replicas established that ancient watercraft could genuinely cross open ocean.
Use-Wear and Residues
Experiment underwrites two forensic methods. Cut a replica blade through hide, then wood, then bone, and each material polishes the edge in a distinct, microscopically recognizable way — so an excavated blade's polish can be read back to its job. And traces of blood, starch, or plant residues surviving on real tools can be identified against experimental references, sometimes to the species.
Reading Ancient Minds
Cognitive archaeology asks what the material record implies about the thinking behind it. Its evidence is behavioural, and its arguments run from capability to concept:
| Evidence | Inference |
|---|---|
| Standardized tool forms across a region | A shared mental template |
| Ochre, beads, deliberate burial | Symbolic behaviour |
| Raw material transported 300 km | Planning, exchange networks |
| Weight standards, tallies, seals | Measurement and accounting |
| Astronomical alignments in monuments | Systematic sky observation |
The limit — and the discipline: archaeology recovers behaviour, and behaviour under-determines belief. A burial with grave goods proves that people treated the dead with care and expense; it cannot, by itself, prove a specific belief in an afterlife of a particular kind. Cognitive archaeology's honest claims are about capabilities — planning, symbolizing, measuring, abstracting — not about doctrines. The best practitioners state the inference and its ceiling in the same breath.
