Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
Prehistoric art
Engraved shells created by homo erectus dating as far back as 500,000 years ago have been found, although experts disagree on whether these engravings can be properly classified as ‘art’. From the Upper Palaeolithic through to the Mesolithic, cave paintings and portable art such as figurines and beads predominated, with decorative figured workings also seen on some utilitarian objects. In the Neolithic evidence of early pottery appeared, as did sculpture and the construction of megaliths. Early rock art also first appeared during this period. The advent of metalworking in the Bronze Age brought additional media available for use in making art, an increase in stylistic diversity, and the creation of objects that did not have any obvious function other than art. It also saw the development in some areas of artisans, a class of people specializing in the production of art, as well as early writing systems. By the Iron Age, civilizations with writing had arisen from Ancient Egypt to Ancient China.
