What is "bad-tibira"

Bad-tibira, "Wall of the Copper Worker(s)", or "Fortress of the Smiths", identified as modern Tell al-Madineh, between Ash Shatrah and Tell as-Senkereh (ancient Larsa) in southern Iraq, was an ancient Sumerian city, which appears among antediluvian cities in the Sumerian King List. Its Akkadian name was Dûr-gurgurri. It was also called (Pantibiblos) by Greek authors such as Abydenus, Apollodorus of Athens and Berossus. This may reflect another version of the city's name, Patibira, "Canal of the Smiths".
