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 and 33 kilometers northeast of ancient Girsu in southern Iraq, was an ancient Sumerian city on the Iturungal canal, which appears among antediluvian cities in the Sumerian King List. Its Akkadian name was Dûr-gurgurri. It was also called Παντιβίβλος (Pantibiblos) by Greek authors such as Berossus, transmitted by Abydenus and Apollodorus. This may reflect another version of the city's name, Patibira, "Canal of the Smiths".

Larsa, also referred to as Larancha/Laranchon by Berossos and connected with the biblical Ellasar, was an important city-state of ancient Sumer, the center of the cult of the sun god Utu with his temple E-babbar. It lies some 25 km (16 mi) southeast of Uruk in Iraq's Dhi Qar Governorate, near the east bank of the Shatt-en-Nil canal at the site of the modern settlement Tell as-Senkereh or Sankarah.
