164 THE TIGRIS RIVER
The streams that join to form the Tigris River begin in the high mountains rimming Lake Van in eastern Turkey. Leaving Turkey, the Tigris touches the northeastern border of Syria and then flows southeastward across Iraq. In Iraq it is joined by tributaries from the east - principally the Great Zab, the Little Zab, and the Diyala. The Euphrates, west of the Tigris, runs in the same general direction. In ancient times, the two rivers had separate mouths. Now they meet in a swamp in southern Iraq and form a single stream, the Shaft al-'Arab, which flows into the head of the Persian Gulf. At 1,900 kilometres, the Tigris is shorter than the Euphrates, but it is more important commercially because its channel is deeper. The fertile region between the Tigris and the Euphrates was called Mesopotamia by the ancient Greeks, and it was here that the earliest known civilization flourished. The Tigris was the great river of Assyria. The ancient city of Assur, which gave its name to Assyria, stood on its banks, as did Nineveh, Assyria's splendid capital. Much later the Macedonian general Seleucus built his capital city Seleucia on the Tigris, and across the river from Seleucia the Parthian kings built Ctesiphon. The chief cities on the river today are Baghdad, the capital of Iraq, and Mosul, farther upstream. River steamers make regular trips between Basra, a modern port on the Shatt al-Arab, and Baghdad.
Since ancient times the people of Mesopotamia have depended on the water of the two rivers to irrigate their hot, dry land. The soil itself is largely a gift of the rivers, which deposit tremendous quantities of silt on their lower course. The shallow Persian Gulf is being filled at the rate of about 20 metres a year, and ruins of cities that were once gulf ports now lie far inland.
