Abstract

THE CHRONOLOGY OF OLD BABYLON Die Venustafeln des Ammi-saduqa und ihre Bedeutung fur die astronomische Datierung der altbabylonischen Zeit. Joachim Mebert (Archiv fur Orientforschung Beiheft, xxxi; Berger & Sohne, Horn, 2010). Pp. 179. 38 (paperback). ISBN 3-900345-10-4.In 1912 F. X. Kugler discovered among omens on sixty-third tablet of Babylonian celestial omen series Enuma Anu Enlil a reference to Year of Golden Throne which he identified with eighth year of Old Babylonian king Ammi-saduqa. Tablet 63 of Enuma Anu Enlil contains a series of omens referring to dates of Venus's first visibility and first invisibility in morning and evening. Kugler suggested that, contrary to other tablets of Enuma Anu Enlil which contain pure omens, tablet 63 contains reports of observations which had been codified as omens. If this suggestion is correct, then Venus data on Enuma Anu Enlil tablet 63 (commonly referred to as the Venus Tablet of Ammi-saduqa) potentially provides means to establish date of reign of Ammi-saduqa and hence to provide a fixed point to pin floating, relative chronology of early second millennium b.c. known from king lists and other historical documents.Many attempts to date Venus Tablet of Ammi-saduqa have been made in hundred years since Kugler' s discovery. By middle of twentieth century, three possible chronologies had emerged: a high chronology in which Ammi-saduqa year 1 = -1710, a middle chronology with Ammi-saduqa year 1 = -1645, and a low chronology with Ammi-saduqa year 1 = -1581. Most Assyriologists and historians of ancient Near East have adopted middle chronology, but on no other grounds than that it is a convenient compromise and appears in all standard reference works. In recent years, several scientifically-trained scholars have argued in favour of other chronologies: P. J. Huber has made a forceful case for long chronology by combining evidence from Venus Tablet with eclipse omens from Enuma Anu Enlil tablets 20 and 21 which he believes refer to specific observations as well as month-length data taken from economic documents.1 V. G. Gurzadyan in a much criticized analysis has argued for a super-short chronology with Ammi-saduqa year 1 = -1549. 2 And most recently, T de Jong and V Foertmeyer have argued for Ammisaduqa year 1 = -1637 on basis of a possible connection with eruption of volcano on Thera.3The book under review presents a new and detailed study of Venus Tablet of Ammi-saduqa and its use in determining Old Babylonian chronology. Mebert begins by discussing Venus Tablet itself. It has long been recognized that tablet as it may be reconstructed from preserved copies is corrupt in various ways. Mebert provides a useful study of structure of tablet in order to extract a subset of omens which he believes are reliable. In order to investigate dates of Venus's visibility phenomena found in these omens, Mebert first investigates Late Babylonian observations of Venus in order to establish values for arcus visionis of phenomena of Venus for Babylon. He then uses these values to calculate dates of Venus's visibility during early second millennium b.c. which can then be compared with dates extracted from Venus Tablet. Next, Mebert compares preserved mo nth -length data from Old Babylonian period with calculated month lengths. By combining results from these two types of evidence, he concludes that most likely date for first year of Ammi-saduqa is -1573. Finally, Mebert investigates other evidence - most of it historical rather than astronomical - to see whether there are any contradictions with his proposed chronology and to provide supporting evidence of his proposed chronological equation. …
