⚠️ Disputed: the sources disagree.

What it is

Selection of sheep with a continuous fleece instead of hair, and shearing or plucking of the wool for spinning. Wool dyes well, keeps warm, and needs no farmland, unlike flax.

Indirect evidence (cull profiles, spindle whorls, archaic Uruk texts); the oldest preserved wool textile dates from the 3rd millennium.

What it led to

  • Huge flocks managed by temples: the Sumerian textile industry and its trade
  • Specialised nomadic herding on the steppe
  • Dyed clothing and woven cloth as a medium of exchange
