На скольких языках говорили в древнем Вавилоне?
For centuries, Akkadian was the native language in Mesopotamian nations such as Assyria and Babylonia. Because of the might of various Mesopotamian empires, such as the Akkadian Empire, Old Assyrian Empire, Babylonia, and Middle Assyrian Empire, Akkadian became the lingua franca of much of the Ancient Near East. However, it began to decline during the Neo-Assyrian Empire around the 8th century BC, being marginalized by Aramaic during the reign of Tiglath-Pileser III. By the Hellenistic period, the language was largely confined to scholars and priests working in temples in Assyria and Babylonia.
