What it is

Stone or clay stamp seals with geometric motifs impressed onto lumps of mud sealing baskets, jars and doors, found by the hundreds in the burnt building at Sabi Abyad. The first system for marking ownership and guaranteeing the integrity of a shipment.

What it led to

  • Personal or family identity encoded in a sign
  • Trust at a distance in exchange: the basis of administered trade
