Radio Carbon (C-14) Results

A number of seed and wood samples from the major site involved in the 10th century debate have been tested and seem to support the new 'low chronology'. Until recently it was impossible to use radiocarbon dating for such relatively 'modern' periods as the Iron Age because its results were expressed within a relatively wide margin of probability, often extending over a century or more. This element of uncertainty made conclusive associations with precise regnal dates quite unreliable. But refinements of C-14 dating techniques have greatly reduced the margin of uncertainty.

A series of samples from Stratum VIA at Megiddo - the city long believed to have been prospered in the 11th century BCE - give dates that cluster decades later. Fifteen wood samples were taken from roof beams that had collapsed in the terrible fire and destruction of stratum VIA.
It must be kept that with these large beams, the C-14 results do not reflect the time of the city's destruction - but the date clearly earlier in which the trees used to make the beams were cut down. Some of them could have been used in earlier buildings; some might have been used for the first time. In other words, only the latest dates in the series should be interpreted as representing the time immediately before the construction of the city. Six of the samples fall in the 12-11th centuries and can well represent reused logs. Eight of the samples fall well into the 10t century and one into the 9th. A calculation of the range of readings, gives an average date for the cutting of the tree at 970 BCE +/- 15 years. Though this is a mere mathematical logic, it provides us with a general direction: the Stratum VI city apparently date to the 10th century BCE.

These dates have been confirmed by test of parallel strata, such as Tel Hadar on the shore of the Sea of Galilee, Ein Hagit near Megiddo and Tel Kinneret on the northern coast of the Sea of Galilee. What is more, a series of samples from the destruction of a stratum at Tel Rehov near Beth-shean which is contemporary with Megiddo's supposed "Solomonic" city, Stratum VA-IVB, gave mid-9th century dates - a long time after its supposed destruction (by Pharaoh Shishak) in 926 BCE (see A. Mazar, IEJ 49, 1999:40-41)
