Iddin-Sin
Iddi-Sin was a King of the Kingdom of Simurrum. Simurrum was an important city state of the Mesopotamian area, during the period of Akkad down to Ur III. Simurrum disappears from records after the Old Babylonian period. According to an inscription, Iddi-Sin seems to have been contemporary with the Lullubi king Annubanini.
Several rulers of the Simurrum Kingdom are known, such as Iddi-Sin and his son Zabazuna. Various inscriptions suggest that they were contemporary with king Ishbi-Erra. In inscriptions, the name of Iddi-Sin is written ??????, with one silent determinative before the remaining part of the name, ?????. ?? can be read as i-ti with the geminated 't' being implied, and then in English the double 't' sound is taken more as a double 'd'. The 'n' is then added in English though not explicitly written in the Akkadian cuneiform. The second ? acts as a determinative for the last part ?? are the signs EN.ZU. Thus all three together form the logogram DEN.ZU, which is read as Sîn, name of the Moon God.
Four inscriptions and a relief of the Simurrum have been identified at Bitwata near Ranya in Iraqi Kurdistan, near the border with Iran, including the large relief now in the Israel Museum, and one from Sarpol-e Zahab. It is thought that the design of the relief is derived from the Victory Stele of Naram-Sin, King of Akkad, in which the king is also seen trampling enemies. It is also similar to other reliefs in the area, such as the Anubanini rock relief. The Sarpol-e Zahab relief, representing a beardless warrior with axe, trampling a foe, and inscribed with the name "Zaba, son of...", may be the son of Iddi-Sin.
Iddi-Sin is also known from a stele, which he inscribed in Akkadian, now in the Sulaymaniyah Museum, Iraq.
A seal showing Iddi-Sin and his son Zabazuna, is also known from the Rosen collection.
