Construction

Ur-Nammu disposes of rivals and rules from the city of Ur (Iraq), becoming the last great ruler of Sumer. He is known for rebuilding the cities and canals, as well as constructing a ziggurat (temple tower) that rises 21 m (70 ft) with a base 60 m (200 ft) wide. See also 2335 bce Archaeology.

The megaron house that becomes the model for much of the housing around the Mediterranean is developed, as revealed by excavations at the lowest level of Troy (Hissarlik, Turkey). A columned porch leads into a narrow hall that passes into the large main room (megaron). Later developments in Greece include another small room behind the megaron for sleeping or storage and a circular hearth. See also 2500 bce Construction.

Mathematics

The oldest preserved standard for length is the foot of the statue of the ruler Gudea of Lagash. It is divided in 16 parts and is 26.45 c (10.41 in.) long. See also 2400 bce Mathematics.

Medicine & health

The oldest medical text that has been preserved in its original form is a cuneiform tablet that lists a sequence of recipes for various external poultices and plasters. See also 2000 bce Medicine & health.
