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 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.
Larsa is thought to be the source of a number of tablets involving Babylonian mathematics, including the Plimpton 322 tablet that contains patterns of Pythagorean triples.
