Some historians have placed the area where Arioch ruled in Anatolia, but theories as to its specific locations differ, with some claiming it was in Pontus while others cite Cappadocia and Antioch.
[4] There are also sources which associated Ellasar with the kingdom of Larsa and suggested that Arioch could be one of its kings called Eri-Aku, an epithet of either Warad-Sin or Rim-Sîn I, since both are described as son of Kudur-Mabuk.
[5] By the 20th century, this theory became popular so that it was common to identify Arioch with Eriaku through the alternative reading of either Rim-Sîn or his brother Warad-Sin, who were both believed to be contemporary with Hammurabi.
[7][8] The identification of Arioch with the ruler Arriuk mentioned in the Mari archives has been recently supported by the Assyrologists Jean-Marie Durand and Stephanie Dalley.
Ellasar is related to the name of Elishah in Genesis 10:4, which is why it is presumed to have referred to Alashiya, an ancient kingdom on Cyprus.
