The invention of the ox-drawn plough was a turning point in the #prehistory of #agriculture because it was the first time food production was decoupled from human labour (doi.org/10.15184/aqy.2019.105).

This is why, from Medieval Europe to the ancient Near East, farms were measured by the number of oxen (later horses etc.) working it, not people (doi.org/10.1002/9781118970959.…)

Yet it's surprisingly difficult to pinpoint when this actually happened.

Steinacleit stone circle and cairn (also called Stein-A-Cleit; Siadar; Shader) on the isle of Lewis up on a boggy moor. "This bundle of stones on a low hill above a loch was originally interpreted as being the remains of a large chambered cairn and stone circle." Photos June 2021.
