The Tanbour, Tool to Raise Water

Raising water from the level of the Nile to the surface of the farmlands was a very important activity in Egypt. An invention called the tanbour made this task easier. The well-known scholar, Archimedes, invented the tanbour during his stay in Alexandria and named it the "Archimedes screw."

It consists of a piece of wood in the form of a screw surrounded by a niched disk. The bottom part of the tanbour is placed in the water and rotated, causing the water to rise to the higher levels. The tanbour was passed down by many generations of Egyptians to the present.

Egyptian peasants still use it in times of low water levels.
