Beyond these valleys are great stretches of uncultivated tracts consisting of plains, hills, and mountains. Some of these tracts are naturally fertile and could be made productive, but at present are used only for pasturage, and over them numberless tribes of fierce nomads drive their flocks of sheep. On the other hand, where the land has no drainage to the sea, so that the streams and rivers that flow into it empty into small lakes or are finally absorbed, the soil becomes impregnated with alkali deposited from the waters, and the grass is scanty. There are also sandy wastes of great extent where scarcely any animal life can exist. Moreover in many parts of the country the rain falls only during a few months of the year, and more abundantly in the higher altitudes, so that the nomads are constantly searching for fresh pasturage, and moving from the lowlands, where the grass dies after the rainy season, to the higher altitudes, from which they return again at the approach of winter. So numerous are the flocks that in the struggle for pasture the weaker tribes are driven to the poorer land.
The pastoral life, the necessity of moving from place to place, the strife resulting from the difference in quality of pasture, have affected the temperament and character of the people. The boundless stretches of land, the clear atmosphere, the burning desert sands, the delicate mirage, and the starry heavens, have made men hospitable, thoughtful, devotional; constant wanderings have made them independent; the struggle for pasturage has made them lawless and cruel. These qualities are reflected to some extent in their woven fabrics, which lack the high artistic finish of those woven in cities. A large proportion of them are prayer rugs and contain symbols of the sun and fire worship. The designs are barbaric, and many are doubtless the same as those used hundreds of years ago. The colours of the old pieces, woven on upland plains or in mountain fastnesses, blend less harmoniously than those woven by more cultured weavers; but they frequently possess rich, pure tones, which are no longer seen in the modern rugs. As even a partial expression of the thoughts and feelings of a people, there are no rugs from the Orient more worthy of study than the rare old pieces woven by nomadic tribes.
Not only physical environment but the conquests of foreign enemies, as well as political struggles at home, have had an important influence on all art. It will be of interest, therefore, to briefly review the histories of Central and Southwestern Asia, where rugs have been made for over three thousand years, in order to understand the different racial influences which have affected their artistic development.

In the rich valleys near the mouths of the Tigris and Euphrates dwelt in the remote past a race of unknown origin called Sumerians, and to the north of them lived another people known as the Accadians. These races built canals, cultivated the soil, established towns, and invented the cuneiform writing. They lived in harmony with one another, and continued to prosper until about 3000 b.c., when the Semitic race of the Chaldees, appearing from an unknown land, subdued them. The Chaldees, however, allowed the conquered races to retain part of their lands, adopted their civilisation, and about the year 2500 b.c. built the city of Babylon, the foundation of which biblical students claim was laid by the mighty hunter Nimrod. By cultivating the surrounding country, by developing its trade and commerce, the Babylonians became a wealthy and powerful nation; and by encouraging manufactures, art, and science, they became noted for their delicate fabrics, magnificent temples, and knowledge of mathematics and astronomy.
About the year 2000 b.c. a number of tribesmen, among whom was Abraham, migrated with their flocks to the upper valleys of the Tigris and founded Nineveh. A century later the land occupied by colonists who settled about Nineveh was known as Assyria. It increased in numbers and in power until, in 1300 b.c., it gained its first victory over Babylon; and during the next four hundred years, though meeting with occasional reverses, it extended its rule over Babylonia, Asia Minor, and Assyria, and received tribute even from Egypt. It thus became the first great conquering power in Southwestern Asia. In their magnificent palaces of Nineveh, surrounded by luxury, the rulers of Assyria were resting in supposed security when a powerful and unexpected enemy appeared from the land now known as Persia.
When the valleys of the Tigris and the Euphrates were inhabited by Sumerians and Accadians, Iran, which included modern Persia, was similarly inhabited by races of unknown origin. Subsequently, but at an exceedingly remote period, from the region about the Oxus river in Western Asia two branches of the great Aryan family migrated to Iran. One of these, which settled in the northern part, was known as the Medes; the other, which settled in the southern part, was known as the Persians. Both Medes and Persians subdued the native races and in the course of centuries constructed powerful empires. The former were the first to extend their conquests, and forming an alliance with the viceroy of Babylon they attacked Nineveh in the year 606 b.c. and destroyed it. Babylon now became the mistress of all Mesopotamia, and under Nebuchadnezzar it was enlarged to cover an area of one hundred square miles, and surrounded by walls three hundred feet high. These walls enclosed parks, orchards, gardens, and a city that soon became famous for its palaces, its temple of Bel, and its Hanging Gardens.
While Babylon was rising in power changes were occurring in Iran. Cyrus, leader of the Persians, instigated a revolt against the Medes and conquered them. But not satisfied with making the Persians rulers of Iran he extended his conquests westward, and in the year 538 b.c., by diverting the waters of the Euphrates, surprised Belshazzar in his banquet hall and became master of Babylonia. The complete subjection of all Asia Minor followed, and for the next two centuries the warlike Persians were the dominant power in Western Asia. But in the year 331 b.c., when Alexander the Great defeated their armies under Darius, the Persian Empire melted away.
