  2. Synchronizing Clocks at Armageddon Workshop on Archaeological Dating Megiddo, Israel, 20 - 22 June 2010 WHY ARE WE HERE? Eli Piasetzky and Israel Finkelstein

  3. Outline The importance of absolute chronology. The accuracy needed The idea of the workshop: join forces for acombined analysis. What can we do here to facilitate such an effort ? Founding Israel Eli (Include spelling mistakes)

  4. The importance of absolute chronology; cases in which archaeology and text converge

  5. The case of biblical history

  6. The case of Greece and the Levant in the Iron Age

  7. The case of Egyptian historical chronology, Tell ed-Daba in the delta of the Nile and the destruction of Thera in the Aegean basin

  8. Why here at Megiddo: Four destructions in 400 years

  9. Stratigraphy of Megiddo; destructions in blue

  10. Why are wehere? K6,M6,H12 VIIA K4,M4,H9 VIA H5 VA-IVB H3 IVA

  11. radiocarbon dating: The invention of radiocarbon Dating W.F. Libby, 1945 W.F. Libby and J. Arnold, Science 110 (1946) 678 W.F. Libby, Radiocarbon dating (U. of Chicago Press, Chicago, 1955) In this workshop: Monday 9:30-13:00 Elisabetta Boaretto Walter Kutchera

  12. Radiocarbon measurements are reported in terms of : “Years before present “ yBP Age calculated Assuming: Atmospheric 14C/12C is constant as it was in 1950 (and the half-life of 14C is 5568 years). Uncertainties in measurements of a sample from this period: Conventional radiometric measurement: 15-20 years (1 σ). AMS: 50-70 years (1 σ). The problem is translating the results to Calendar age. Complications are due to the variations in the radiocarbon concentration in the atmosphere

  13. radiocarbon dating: Calibration using known dendro-chronological dates. Bristlecone Pines in the U.S.A Waterlogged Oaks in Ireland and Germany Allow extension of the calibration over the last 11,000 years. 1998Radiocarbon 40(3) 1127-1151 Stuiver M., P.J. Reimer and T.F.Braziunas

  14. Problems due to the calibration procedure: The calibration curve has an uncertainty of about 10 years in this period that increases the overall uncertainty. Several possible ranges. Extended ranges The calibration destroy the “normal distributions” nature of the results.

  15. Lachish III was destroyed in Sennacherib's campaign against Judah 701 BCE. The pottery assemblage of Lachish III (Iron IIB) clearly is later than that of Beth-Shemesh 3 (Iron IIA/B). Narrowing 14C according to constrains which stem from the Assyrian records (766-551) (766-745) BCE

  16. Improving the 14C laboratory measurement do not help so much 68% range

  17. 14C measurement and another independent measurement Assuming the other measurement yield 750±100 BCE (σ=100 years) 68% range is: 775-609 BCE (166 years) Assuming the other measurement yield 750±50 BCE (σ=50 years) 68% range is: 776-724 BCE (52 years)

  18. THE NEW TEL REHOV 14C READINGS: TWO ALTERNATIVE INTERPRETATIONS WITH THE SAME CALIBRATION CURVE VI V IV Shishak’s campaign THE TEL REHOV TEAM (CONVENTIONAL CHRONOLOGY) Bruins et al., Science 2003 300: 315-318 FINKELSTEIN-PIASETZKY (LOW CHRONOLOGY) VI V IV Israel Finkelstein and Eli Piasetzky Science Oct 24 2003: 568.

  19. The average uncalibrated date is: 2768 ± 12 yBP. 32 years 27 years 47 years 48 years

  20. combined analysis Do not beat them, join them The main motto of the workshop: Not need to find a better / alternative methods to radiocarbon. Combining the information from different methods can increase the overall dating accuracy and reliability. Even methods that yield results which are less accurate than radiocarbon can improve significantly our overall dating capability.

  21. Radiocarbon: Elisabetta Boaretto and Walter Kutchera Temporal variation of the Earth’s magnetic field: Amotz Agnon Luminescence Noami Porat RHX Miora Wilson and Christopher Hall What can we do here to facilitate a combined effort ?

  22. Israel Science Foundation : Inter Universities Research Centers “The program is designed to support excellent research groups, particular ly in universities, in order to promote broad research activity at the highest level on a large scale…to develop innovative research areas in basic research in universities and encourage research initiatives - disciplinary.” “The program requires participation of several research teams of independent joint project.” “Support research focus is eight years” “The first period of the grant funding (4 years) is up $ 1.5 million in the Natural Sciences and $ 750,000 in the Humanities and Social .Sciences” ~400,000 $ / year Submission dead line: 1 Dec 2010 EU options ?
