The capital of the Elamites was the city of Susa, where excavations have revealed traces of an independent civilization which reaches back to an early period in the Late Stone Age. Susa is referred to in the Old Testament--"The words of Nehemiah.... I was in Shushan the palace".[144] An Assyrian plan of the city shows it occupying a strategic position at a bend of the Shawur river, which afforded protection against Sumerian attacks from the west, while a canal curved round its northern and eastern sides, so that Susa was completely surrounded by water. Fortifications had been erected on the river and canal banks, and between these and the high city walls were thick clumps of trees. That the kings of Elam imitated the splendours of Babylonian courts in the later days of Esther and Haman and Mordecai, is made evident by the Biblical references to the gorgeous palace, which had "white, green, and blue hangings, fastened with cords of fine linen and purple to silver rings and pillars of marble; the beds were of gold and silver, upon a pavement of red, and blue, and white, and black marble ".[145] Beyond Elam were the plains, plateaus, and grassy steppes occupied by the Medes and other peoples of Aryan speech. Cultural influences came and went like spring winds between the various ancient communities. For ten long centuries Sumer and Akkad flourished and prospered ere we meet with the great Hammurabi, whose name has now become almost as familiar as that of Julius Caesar. But our knowledge of the leading historical events of this vast period is exceedingly fragmentary. The Sumerians were not like the later Assyrians or their Egyptian contemporaries--a people with a passion for history. When inscriptions were composed and cut on stone, or impressed upon clay tablets and bricks, the kings selected as a general rule to record pious deeds rather than to celebrate their victories and conquests. Indeed, the average monarch had a temperament resembling that of Keats, who declared: The silver flow Of Hero's tears, the swoon of Imogen, Fair Pastorella in the bandits' den, Are things to brood on with more ardency Than the death day of empires. The Sumerian king was emotionally religious as the great English poet was emotionally poetical. The tears of Ishtar for Tammuz, and the afflictions endured by the goddess imprisoned in Hades, to which she had descended for love of her slain husband, seemed to have concerned the royal recorder to a greater degree than the memories of political upheavals and the social changes which passed over the land, like the seasons which alternately brought greenness and gold, barrenness and flood.
