About the Cover
Excavation in 1989 of the Lower Town of Tell Leilan, a large third millennium city in northern Mesopotamia (present-day northeast Syria); the excavation exposed 600 square meters of an urban street and a residential area occupied from 2600 to 2200 B.C. After a volcanic event, which deposited tephra on the roofs of these houses, and a subsequent abrupt change in climate, much of northern Mesopotamia was abandoned.
