“I cannot discuss here the philological evidence that anchors the biblical tradition in the historical charts. This is a different, albeit very important field which may support my arguments: I just mention one recent example: Jeremiah 39:3 may go back to an eye witness’s account of Nebuchadnezzar’s conquest of Jerusalem in 589 BCE.
This is indicated by my colleague Michael Jursa’s identification of the chief-eunuch Nabu-sharrussu-ukin, the biblical נכו שרםכים רכםרים or Nebu-Sarsekim, in an economic document from the sun-god temple in Sippar, dated to the “Month XI, day 18, year 10 Nebuchadnezzar, king of Babylon.”
(M. Jursa, “Nabû-šarrūssu-ukīn, rab ša-rēši, und ‘Nebusarsekim’ (Jeremiah 39:3),” NABU 5 (2008). Jursa’s translation of the document runs as follows:
“Regarding] 1.5 minas (0.75 kg) of gold, the property of Nabû-šarrūssu-ukīn, the chief eunuch, which he sent via Arad-Bānītu the eunuch to [the temple] Esangila: Arad-Bānītu has delivered [it] to Esangila.
In the presence of Bēl-usāti, son of Alpāya, the royal bodyguard, [and of] Nādin, son of Marduk-zēru-ibni. Month XI, day 18, year 10 [of] Nebuchadnezzar, king of Babylon.”
We may note here that the evaluation of this document provoked a broad discussion in scholarly literature and in the Internet.)
The Babylonian exile had a major impact on the development of Judaism, possibly even on the moulding of the apocalyptic traditions.
(Jeremiah 39:3 gives account of Nebuchadnezzar’s conquest of Jerusalem and his victory over the Judean King Zedekiah: The passage reports that all of the officers of the king of Babylon made their entry, and occupied the middle gate.)
(Kvanvig, Roots, writes: “The emergence of the apocalyptic traditions and literature presupposes both a direct contact with Mesopotamian culture in the Babylonian diaspora, and the syncretistic tendencies in Palestine in the post-exilic centuries.” See also Sarah Robinson, “The Origins of Jewish Apocalyptic Literature: Prophecy, Babylon, and 1 Enoch,” MS Thesis, University of South Florida, 2005.)
The background of this “knowledge transfer,” however, is the scholarly situation as just described. I say this not to deny the contribution of mere story-telling and fantastic lore to the growth of the corpus of apocalyptic literature, but we cannot neglect the scholarly and even empirical background of the underlying world-view.
Indeed, this may provide the best explanation for why so many different topics and stylistic features are fused in the extant Enochic traditions.
What concerns us here is the heuristic attitude of Mesopotamian scholarship. Even in the late Seleucid period this scholarship remains basically “holistic” or “monistic” in the way that it links all sorts of empiricism, as may be demonstrated with examples from the famous “Astronomical Diaries.”
(We follow here the unpublished manuscript of G. Graßhoff, “The Diffusion of Knowledge: From Babylonian Regularities to Science in the Antiquity” (paper presented at the 97th Dahlem Workshop on Globalization of Knowledge and its Consequences at the Dahlem Konferenzen, Berlin, 18-23 November 2007).
In the fifth year of Darius III (331 BCE) we find a series of astronomical observations:
“Day 13 [20 September]: Sunset to moonrise 8. There was a lunar eclipse. Its totality was covered at the moment when Jupiter set and Saturn rose. During totality the west wind blew, during clearing the east wind. During the eclipse, deaths and plague occurred.
Day 14: All day clouds were in the sky …”
The reports then continue with observations from the “Burse of Babylon”; commodity prizes are given together with the positions of the planets in the zodiacal signs.
“That month, the equivalent for 1 shekel of silver was: barley . . . at that time, Jupiter was in Scorpio; Venus was in Leo, at the end of the month in Virgo; Saturn was in Pisces; Mercury and Mars, which had set, were not visible.”
The reports further continue with the famous account of the downfall of the Persian empire in the same year, after the battle at Gaugamela, north of Mosul (331 BCE).”
