3.2.1 The Rise and Eclipse of Sumer

The term Mesopotamia, or “the land between the rivers” in Greek, likely originated with the Greek historian Herodotus in the fifth century BCE and has become the common name for the place between the Tigris and Euphrates Rivers in what is now Iraq. The rivers flow north to south, from the Taurus Mountains of eastern Turkey to the Persian Gulf, depositing fertile soil along their banks. Melting snow and rain from the mountains carry this topsoil to the river valleys below. In antiquity, the river flow was erratic, and flooding was frequent but unpredictable. The need to control it and manage the life-giving water led to the building of cooperative irrigation projects.

Agricultural practices reached Mesopotamia by around 8000 BCE, if not earlier. However, for about two millennia afterward, populations remained quite small, typically living in small villages of between one hundred and two hundred people. Beginning around 5500 BCE, some had begun to establish settlements in southern Mesopotamia, a wetter and more forbidding environment. It was here that the Sumerian civilization emerged (Figure 3.8). By around 4500 BCE, some of the once-small farming villages had become growing urban centers, some with thousands of residents. During the course of the fourth millennium BCE (3000s BCE), urbanization exploded in the region. By the end of the millennium, there were at least 124 villages with about one hundred residents each, twenty towns with as many as two thousand residents, another twenty small urban centers of about five thousand residents, and one large city, Uruk, with a population that may have been as high as fifty thousand. This growth helped make Sumer the earliest civilization to develop in Mesopotamia.

The fourth millennium BCE in Sumer was also a period of technological innovation. One important invention made after 4000 BCE was the process for manufacturing bronze, an alloy of tin and copper, which marked the beginning of the Bronze Age in Mesopotamia. In this period, bronze replaced stone as the premier material for tools and weapons and remained so for nearly three thousand years. The ancient Sumerians also developed the plow, the wheel, and irrigation techniques that used small channels and canals with dikes for diverting river water into fields. All these developments allowed for population growth and the continued rise of cities by expanding agricultural production and the distribution of agricultural goods. In the area of science, the Sumerians developed a sophisticated mathematical system based on the numbers sixty, ten, and one.

One of the greatest inventions of this period was writing. The Sumerians developed cuneiform, a script characterized by wedge-shaped symbols that evolved into a phonetic script, that is, one based on sounds, in which each symbol stood for a syllable (Figure 3.9). They wrote their laws, religious tracts, and property transactions on clay tablets, which became very durable once baked, just like the clay bricks the Sumerians used to construct their buildings. The clay tablets held records of commercial exchanges, including contracts and receipts as well as taxes and payrolls. Cuneiform also allowed rulers to record their laws and priests to preserve their rituals and sacred stories. In these ways, it helped facilitate both economic growth and the formation of states.

The Invention of Writing in Sumer

Writing developed independently in several parts of the world, but the earliest known evidence of its birth has been found in Sumer, where cuneiform script emerged as a genuine writing system by around 3000 BCE, if not earlier. But questions remain about how and why ancient peoples began reproducing their spoken language in symbolic form.

Archaeologist Denise Schmandt-Besserat argued in the 1990s that small clay representations of numbers and objects, often called “tokens,” date from thousands of years before the development of cuneiform writing and were its precursor. These tokens, she believed, were part of an accounting system, and each type represented a different good: livestock, grains, and oils. Some were found within hollow baseball-sized clay balls now called “bullae,” which were marked with pictures of the tokens inside. Schmandt-Besserat believed the pictures portray the type of transaction in which the goods represented by the tokens were exchanged, and thus they were a crucial step toward writing. Over time, she suggested, the marked bullae gave way to flat clay tablets recording the transactions, and the first truly written records emerged (Figure 3.10).

Figure 3.10 One theory holds that the antecedents of Sumerian clay tablets inscribed with writing like this one (a) were small clay tokens (b) and the pictures of them on the clay “bullae” vessels that held them.

Schmandt-Besserat’s linear interpretation is still one of the best-known explanations for the emergence of writing. But it is hardly the only one. One scholar who offers a different idea is the French Assyriologist Jean-Jacques Glassner. Glassner believes that rather than being an extension of accounting techniques, early writing was a purposeful attempt to render the Sumerian language in script. He equates the development of writing, which gives meaning to a symbol, to the process by which Mesopotamian priests interpreted omens for divining the future. Writing allowed people to place language, a creation of the gods, under human control. Glassner’s argument is complex and relies on ancient works of literature and various theoretical approaches, including that of postmodernist philosopher Jacques Derrida.

Many disagree with Glassner’s conclusions, and modern scholars concede that tokens likely played an important role, but probably not in the linear way Schmandt-Besserat proposed. Uncertainty about the origin of writing in Sumer still abounds, and the scholarly debate continues.

• Why do you think Schmandt-Besserat’s argument was once so appealing?
• If you lived in a society with no writing, what might prompt you to develop a way to represent your language in symbolic form?

Cuneiform was a very complex writing system, and literacy remained the monopoly of an elite group of highly trained writing specialists, the scribes. But the script was also highly flexible and could be used to symbolize a great number of sounds, allowing subsequent Mesopotamian cultures such as the Akkadians, Babylonians, and many more to adapt it to their own languages. Since historians deciphered cuneiform in the nineteenth century, they have read the thousands of clay tablets that survived over the centuries and learned much about the history, society, economy, and beliefs of the ancient Sumerians and other peoples of Mesopotamia.

The Sumerians were polytheists, people who revered many gods. Each Sumerian city had its own patron god, however, one with whom the city felt a special connection and whom it honored above the others. For example, the patron god of Uruk was Inanna, the goddess of fertility; the city of Nippur revered the weather god Enlil; and Ur claimed the moon god Sin. Each city possessed an immense temple complex for its special deity, which included a site where the deity was worshipped and religious rituals were performed. This site, the ziggurat, was a stepped tower built of mud-brick with a flat top (Figure 3.11). At its summit stood a roofed structure that housed the sacred idol or image of the temple’s deity. The temple complex also included the homes of the priests, workshops for artisans who made goods for the temple, and storage facilities to meet the needs of the temple workers.

Sumerians were clearly eager to please their gods by placing them at the center of their society. These gods could be fickle, faithless, and easily stirred to anger. If displeased with the people, they might bring famine or conquest. Making sure the gods were praised and honored was thus a way of ensuring prosperity. Praising them, however, implied different things for different social tiers in Sumer. For common people, it meant living a virtuous life and giving to the poor. For priests and priestesses, it consisted of performing the various rituals at the temple complexes. And for rulers honoring the gods, it meant ensuring that the temples were properly funded, maintained, and regularly beautified and enlarged if possible.

By the Early Dynastic Period (c. 2650 BCE–2400 BCE), powerful dynasties of kings called lugals had established themselves as rulers of the cities. In each city, the lugals rose to power primarily as warlords, since the Sumerian cities often waged war against each other for control of farmland and access to water as well as other natural resources. Lugals legitimized their authority through the control of the religious institutions of the city. For example, at Ur, the daughter of the reigning lugal always served as the high priestess of the moon god Sin, the chief deity at Ur.

The lugals at Ur during this period, the so-called First Dynasty of Ur, were especially wealthy, as reflected in the magnificent beehive-shaped tombs in which they were buried. In these tombs, precious goods such as jewelry and musical instruments were stored, along with the bodies of servants who were killed and placed in the tomb to accompany the rulers to the Land of the Dead. One of the more spectacular tombs belonged to a woman of Ur called Pu-Abi, who was buried wearing an elaborate headdress and might have been a queen (Figure 3.12). The most famous lugal in all Sumer in this early period was Gilgamesh of Uruk, whose legendary exploits were recounted later in fantastical form in the Epic of Gilgamesh.
