Eridu at English => English (The Britannica Concise) Of Explained:
Ancient city, on the Persian Gulf. While it was the chief seaport of Sumer and Babylonia, and was located near Ur and the Euphrates, its coastline has filled in, and the site is now 120 mi (193 km) inland, in modern Iraq. It was revered as the oldest city in Sumer, and its patron god was Enki (Ea). Founded on sand dunes c.5th millennium BC, its ruins show the sequence of the preliterate Ubaid civilization, with a long succession of superimposed temples portraying the development of an elaborate mud-brick architecture. It was occupied until c.600 BC.
