Ninus, according to Greek historians writing in the Hellenistic period and later, was the mythical founder of Nineveh, ancient capital of Assyria. His name is not attested on the Assyrian King List or in any cuneiform literature; he does not seem to represent any one personage known to modern history, and is more likely a conflation of several real and/or fictional figures of antiquity, as seen to the Greeks through the mists of time.
