The diorite of Sinai was not the only material which was imported into Babylonia for the buildings of Gudea. Beams of cedar and box were brought from Mount Amanus at the head of the Gulf of Antioch, blocks of stone were floated down the Euphrates from Barsip near Carchemish, gold-dust came from Melukhkha, the "salt" desert to the east of Egypt which the Old Testament calls Havilah; copper was conveyed from the north of Arabia, limestone from the Lebanon ("the mountains of Tidanum"), and another kind of stone from Subsalla in the mountains of the Amorite land. Before beams of wood and blocks of stone could thus be brought from the distant West, it was necessary that trade between Babylonia and the countries of the Mediterranean should have long been organized, that the roads throughout Western Asia should have been good and numerous, and that Babylonian influence should have been extended far and wide. The conquests of Sargon and Naram-Sin had borne fruit in the commerce that had followed upon them. Once more the curtain falls, and Canaan is hidden for a while out of our sight. Babylonia has become a united kingdom with its capital and centre at Babylon. Khammurabi (B.C. 2356-2301) has succeeded in shaking off the suzerainty of Elam, in overthrowing his rival Eri-Aku, king of Larsa, with his Elamite allies, and in constituting himself sole monarch of Babylonia. His family seems to have been in part, if not wholly, of South Arabian extraction. Their names are Arabian rather than Babylonian, and the Babylonian scribes found a difficulty in transcribing them correctly. But once in the possession of the Babylonian throne, they became thoroughly national, and under Khammurabi the literary glories of the court of Sargon of Akkad revived once more.
