Figure 3.1 The Art of Ur. This intricately ornamented box of mosaic-covered wood was found in a royal tomb in the ancient city of Ur. It dates from about 2550 BCE and exhibits several markers of this era’s civilizations, such as a hierarchical society (as the scenes illustrate) and the presence of wealth, leisure, and specialized skills needed to make such an elaborate decorative object.

The land of Sumer, in today’s southern Iraq, was home to some of the largest early cities in human history. In one of these ancient settlements, Ur, a beautiful wooden box was laid in a royal tomb in about 2550 BCE (Figure 3.1). It measures roughly nine by twenty inches (a little bigger than a laptop) and is inlaid with elaborate mosaic figures and borders composed of bits of red limestone, lapis lazuli, and marine shell. This kind of specialized craftsmanship was a hallmark of societies that no longer depended on hunting and gathering for food but rather produced crops capable of sustaining large populations. In turn, they gained enough time and prosperity for some members to focus on artisanal crafts.

The box indicates at least three important things about the civilization that produced it. First, a highly skilled artisan constructed the box and created the mosaics, indicating the presence of specialization of labor. Second, the mosaics show someone who is presumably the king at the center of the top row, directing the soldiers below. These power dynamics suggest new social hierarchies. Finally, the soldiers all appear smaller in the scene than the king, symbolically reflecting their subordinate position and telling us that social stratification had come into existence. All these developments took place gradually over time, bringing slow but enduring change to the lives of the people in Ur and those who lived nearby. Similar changes occurred in the world’s other ancient cities.
