Additional tests were done on six grain samples from the destruction level resulting in dates between and B.

My dating of the destruction of Jericho to ca.

However, it was later found that the calibration system and instrumentation of the British Museum's radiocarbon apparatus were giving wrong answers.

Not jericho carbon dating confirm

This, of course, was no reflection on Wood's scholarship; he was reporting the results that everyone assumed to be correct when he wrote the BAR article. These radiocarbon results were superseded by a later study that examined various pieces of wood from Jericho and, more importantly, samples taken from the grain supply.

Is there any explanation for this seeming contradiction between the date derived from archaeological evidence and that given by radiocarbon C 14 analysis?

InBruins and van der Plicht published a report on the radiocarbon measurements of some wood samples and also on grain samples taken from Jericho City IV Bruins and van der Plicht, As expected, the wood charcoal samples gave an average age a few decades earlier than the grain samples, and so the six grain samples have been used as the primary indicator of when the city met its fiery destruction.

apologise, but

These six samples produced a result of years BP Before Present with an impressive standard deviation of plus or minus only 7 years. The very small standard deviation reflects favorably on the careful sample preparation of the investigators and the accuracy of their mass spectrometer.

There is no reason to question this initial result, and if that were all there were to it, it might be thought that the date of Jericho's destruction could now be ascertained, with a high degree of certainty, to within a year interval.

The earlier dating of the destruction is based on carbon dating and the absence of certain pottery styles. But Bryant Wood argues that this allegedly 'missing' pottery style from the Late Bronze was actually found at Jericho, and we've included photos of some of this pottery in this article and the previous one by Dr Wood. Initially, a C14 date of /- 40 B.C. (done by the British Museum) was published for charcoal from the destruction level of Jericho (Jericho V , p. ). Early bronze Jericho; high-precision super 14 C dates of short-lived palaeobotanic remains. Abstract Reliable series of high-precision radiocarbon dates in a stratified archaeological context are of great importance for interdisciplinary chronological and historical studies.

Anyone familiar with radiocarbon techniqueshowever, knows that such is not the case. The problem is that a simple comparison of C 12 to C 14 ratios, such as gives the "BP" value, would not give the true age of a sample unless several conditions were satisfied.

One of those conditions is that the rate of C 14 production by cosmic rays in the upper atmosphere has been constant over time, an assumption that is generally recognized as invalid. Therefore, over the years various checks have been applied to the basic BP values to see if there was a need for adjustment to the BP readings.

are mistaken

The principal adjustment method is to compare BP values to the values given by tree-ring analysis, i. The refinement of these adjustments is an ongoing study, and the results are published as calibration curves that transform BP values into historic BC or AD years.

Bruins and van der Plicht mention four calibration curves that they could choose from.

useful piece Same

The calibration system they settled on gave the following result: the BP figure plus or minus 7 years produces two date ranges for the samples: BC or BC.

These date ranges the ranges express the 1-sigma variation in each range have median values 41 years apart, compared to the 7 year standard deviation in the original BP value derived from mass spectrographic analysis.

The most curious thing about these results is not that the four different calibration systems give different results, although the reconciliation of the various C 14 calibration curves is of course a matter of much interest in the scholarly literature. The intriguing question is: how did the careful mass spectroscopic analysis that produced a ratio of C 14 to C 12 for which there was only a plus or minus seven year deviation figure for a period of 36 centuries, nevertheless come up with not one but two adjusted BC dates?

Would anyone trust a calculator or computer that, given one very precise input, produces two answers for us to choose from? This strange result two answers to choose from is because all calibration curves considered for use in this study showed a wiggle in the curve at just the time of interest, namely the middle of the second millennium BC.

The wiggle the curve essentially going back on itself means that if you put in one BP date you will get out two BC dates. Physically, of course, this is not reasonable.

Can jericho carbon dating not puzzle over

The grain was all harvested in the same year, or at the most in two successive years. Yet this strange phenomenon is familiar to physicists doing C 14 studies in the time range of the 16th and 15th centuries BC.

sorry, that has

For the unbiased observer, however, it should be clear that there are some genuine questions that can be raised about the reliability of the radiocarbon dates of the Jericho grain samples.

Prudence would dictate that until the anomalous phenomena of C 14 dating for this time can be explained, it would be better to rely on historical indicators for dating events in the middle of the second millennium BC rather than on radiocarbon results.

The anomalous C 14 results are not confined to Jericho. The Thera volcanic eruption article cites archaeologists who insist that the date range given by radiocarbon analysis small grains for the eruption of Thera, namely to BC, must be reduced by from to years if there is to be any consistency with dates that the Egyptologists give for Egypt's New Kingdom.

The second date range, to BC, would be reduced to to BC. Here there is inexactitude not only because of the calibrated C 14 results, but also because of the few decades but not a century of uncertainty to years decrease in the amount of adjustment recommended by the Egyptologists see the Thera article.

Debunking Creationism: \

Nevertheless, the Egyptologists would insist that their figures cannot be reconciled with the radiocarbon results unless those are adjusted down by to years. These recent developments and ongoing controversy in the field of radiometric analysis were unknown when Wood published his BAR article calling for a reexamination of the archaeological data published by Garstang and Kenyon.

opinion you

If it is decided that the dust needs to settle in this dispute before the C 14 evidence can be evaluated fairly, then the dates for Jericho City IV should be determined solely based on archaeological arguments. If, however, the revision in C 14 dates in the mid-second millennium BC called for by the Egyptologists is right, then all conflict between radiocarbon measurements and archaeological evidence for the date of the fall of Jericho City IV would be resolved. That resolution would rule out the date that is currently in favor in most secular publications, and explain why it is in contradiction to the archaeological data.

sorry, that interfere

If such a resolution to the conflict were to come about, then Dr. Wood's reexamination of the Jericho data will surely be recognized as a major contribution to the understanding of the history of Egypt and the Levant in the second millennium BC.

There is an interesting consequence to this that results if either of the alternatives is chosen-that of the physicists or that of the Egyptologists. It has just been mentioned that the solution of the Egyptologists requires a down-dating of C 14 results.

Shaking, support. jericho carbon dating seems

Those who advocate the Biblical trustworthiness will definitely prefer this alternative. But the other option, namely that Egyptian dates for the 18th Dynasty must be ated about years to conform to C 14 results, would also be fatal to Kenyon's interpretation of the archaeological data.

think, that

The reason is that her date of ca. According to Kenyon's writing also verified by Garstang, Wood, and other archaeologiststhis destruction was followed by about years in which the city was basically uninhabited. This is the chief argument that has been used for over 50 years now against the historicity of the Biblical account of Jericho.

But although the year adjustment can be made to the stratigraphic and pottery findings, it cannot be made to the C 14 results under the assumption that the physicists are right.

The grain found in Jericho's storage jars would still be dated to about BC, which is in the time that the adjusted Kenyon dates would dictate that the city was uninhabited.

Very grateful jericho carbon dating words... super

This is fatal to Kenyon's entire dating scheme. Either solution-that of the Egyptologists or that of the physicists-cannot be supported by Kenyon's conclusion that Jericho fell at about the time of the beginning of the New Kingdom, whether that was in the middle of the 16th century BC unadjusted date or years earlier adjusted date.

This is the consequence that seems inescapable once the dilemma posed by the current controversy over C 14 dating in the middle of the 2nd millennium BC is fully grd.

Kenyon's conclusion that Jericho fell at about the time the 18th Dynasty began cannot be reconciled with either solution to the dilemma. Currently the only solution that seems to have any semblance of credibility is the Biblical solution: Jericho fell to the armies of Israel in the latter part of the 15th century BC, and the C 14 evidence, properly interpreted and adjusted, now supports the Biblical account.
