Absolute Mesopotamian chronology

The 614 Assyrian eponyms between the first year of Šamšî-Adad I and the first year of Tiglath-pileser I (1115-1076) allow us to date approximately the reign of Šamšî-Adad I (1728-1695). As the Assyrian years were lunar before the reign of Ninurta-apil-Ekur (1192-1179) this makes it possible to slightly correct the reign of Šamšî-Adad I (1712-1680) yet as this Amorite king died in the 17th/18th year of King Hammurabi so this synchronism fixes the dating of this Babylonian king (1697-1654). This dating does not correspond to the Middle Chronology but exactly satisfies the astronomical dating of the Ammisaduqa tablet on Venus according to the Ultra-Low Chronology. In addition one tablet of astronomical omens (Enuma Anu Enlil 20) mentions a lunar eclipse dated 14 Simanu at the end of the reign of Šulgi (14/III/48 27 June 1954 BCE) and another (Enuma Anu Enlil 21) mentions a lunar eclipse dated 14 Addaru at the end of the third dynasty Ur which ended with the reign of Ibbi-Sin (14/XII/24 6 March 1911 BCE). These two total lunar eclipses are separated by 42 years of reign (= 9 years of Amar-Sin + 9 years of Šu-Sîn + 24 years of Ibbi-Sin) and 9 months (=XII - III). During the period 2200-1850 BCE there was only one couple of lunar eclipses spaced 42 years and 9 months apart and visible at Ur corresponding to the description of the astronomical omens. These two total lunar eclipses confirm the absolute dating of the reign of Hammurabi (1697-1654) and allow to anchor the reign of Sargon of Akkad (2243-2187). Secondly as there is a synchronism between Neferhotep I (1701-1690) and Ibni-Addu (1700-1680) the king of Hazor and another synchronism between Ibni-Addu and Hammurabi (1697-1654) the king of Babylon this reign could be determined indirectly by carbon-14 and is again in perfect agreement with the Ultra-Low chronology. Finally the best confirmation of the accuracy of this absolute chronology is the complete reconstitution from 2040 to 1050 BCE year by year of the main Mesopotamian chronologies: Uruk IV Mari Gutium Assyria Elam Uruk V Ur III Larsa Isin I Babylon Hana Kassite and Sealand with their synchronisms as well as their dates anchored on astronomical phenomena such as the total eclipses of the moon (Gertoux NABU 2021-3 171-172).
