ABRAHAM’S HOME Ur of the Chaldees, as the Bible calls it, was the home of the Old Testament patriarch Abraham. The mosaic at left, on a wooden box thought to have been part of a musical instuments, shows a kinjg of Ur at ease with a drink. The box was made in about 2800-2700 B.C.
COLLAPSIBLE BOATS
Traders in ancient Sumeria, in southern Mesopotamia, devised a simple but ingenious way to make the best use of river transport. Upstream they built boats of hides stretched over light wooden frames. The boats were loaded with whatever cargo was to be shipped with the current to their destination.
Once the cargo was unloaded, the boat was knocked apart, and its wooden parts were sold to the timber-poor cities of the south. The crew then loaded the hides onto the donkey and walked back, having saved themselves all the problems of propelling a boat upriver against the current. At the other end they built a new frame, covered it with the old hides, and were ready to set off again.
A relief carved on the wall of a palace built at Nineveh in the 7th century B.C. for the Assyrian king Sennacherib shows one of these leather boats carrying stone down the river Tigris. Even today, similarly made boats are still used on the Euphrates.
EARLIEST LIBRARIES
Records of commercial transactions, religious practices, political history, popular legends, government accounts, and mathematical and astronomical discoveries are by no means isolated survivals from ancient Mesopotamian civilization. Hundreds of thousands of clay tablets-all covered with the wedge-shaped writing known as cuneiform-have survived to the present day, partly because the Sumerians and Babylonians wrote down a great deal and also because dry, sun-baked clay is almost imperishable.
Several collections of tablets, so numerous that they can only be called libraries, have come to light. Excavations begun in 1933, at a site called Tell Hariri, in eastern Syria, uncovered the archives of the ancient Mesopotamian city of Mari.
The archives contained 23,600 tablets, coveringn a period of 530 years, between 2285 and 1755 B.C. Another library, compiled for the Assyrian king Assurbanipal in the 7th century B.C. contained specially commissioned Sumerian and Assyrian grammars and dictionaries, which have provided scholars with an invaluable key to these ancient languages.
