The birthplace of the Sumerian civilization

The paper studies the location of the Dilmun region based on ancient sources. Along with the Sumerian and ancient Greek sources the achievements of modern researchers from related fields are involved. It has been established that the Euphrates and Tigris rivers discharged into the Persian Gulf during the time of the Sumerian civilization. Therefore, based on the materials studied, the author determined the localization of Dilmun Island around Sanam Mountain, located in the southern part of the Iraqi province of Basra. It is this area that corresponds to the existence of Dilmun both in prehistoric times and in ancient times. The proposed article together with other studies on this issue allows to take a fresh look at the development of the Sumerian civilization.
