What it is

Hull of cedar planks sewn or joined with tenons, propelled by a square sail on a bipod mast and oars. The Egyptian 'Byblos ships' and the Abydos boats (c. 3000 BCE) inaugurate seagoing navigation in the eastern Mediterranean.

The earliest depiction of a sail is on a Naqada II vessel (c. 3300 BCE); the Abydos boats are riverine, and the first documented sea voyage to Byblos dates to the reign of Sneferu (c. 2600 BCE).

What it led to

  • Regular maritime trade linking Egypt, Lebanon, Crete and Cyprus in cedar, copper, tin, wine and oil
  • Minoan thalassocracy and trade networks connecting the Aegean with the East
  • Wrecks such as Uluburun (c. 1300 BCE): the world economy of the Late Bronze Age
  • Expeditions to Punt and state-sponsored voyages of exploration
