Both the earliest civilizations, the Egyptian and the Mesopotamian, make extensive use of boats for transport on the Nile, Euphrates and Tigris. The Nile in particular provides a superbly predictable thoroughfare, for the wind always blows from north to south and the current always flows from south to north. Egyptian boats sail upstream, hoisting a large rectangular sail, and then are rowed back down the river.
This distinction is even reflected in the Egyptian hieroglyphs for travelling south (a boat with a sail up) and travelling north (a boat being rowed).
The
Egyptians, with access to the Mediterranean, also use larger seagoing
vessels. These become known as 'Byblos' boats, revealing that their
trade is with the eastern coast of the Mediterranean. Byblos is the main
port for the export of the valuable cedar wood of Lebanon, essential
for Egypt's architecture and for boat-building. One of the earliest
known boats, buried beside a pyramid at Giza and dating from around 2500
BC, is made from planks of cedar; it is 143 feet (44m) long and 20 feet
(6m) wide.
