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.
Blyth, Northumberland
Little is known of the early development of the Blyth area. The oldest archaeological find is an antler hammer dating from the late Neolithic or early Bronze Age period, which was found at Newsham in 1979.
Human skulls, a spearhead and a sword dating from the Bronze Age were found in the river in 1890, as well as a bronze axe which was found at South Beach in 1993, and a dagger found at Newsham. Although there is no conclusive evidence of a Roman presence in the area, an earthwork shown on early mapping of the area, at the location of present-day Freehold Street, is said to have been a Roman camp, but it has also been argued that it may be of Norsemen origin or date from the Civil War. Debate also surrounds a mosaic which was found near Bath Terrace. The strongest evidence so far has been a single coin, dating from the reign of the Emperor Constans (AD337–350), which was found during excavations for a dry dock. Also four Roman coins were found when digging an air raid shelter in a back garden on Chestnut Avenue.
