For absolute dating, radiocarbon analysis was conducted on nine samples consisting of 4–8 tree rings, relatively dated and coming from selected timbers, of which dendrochronological sequences defined the above chronology.
The wiggle-matching method allowed to determine the two most plausible periods tree cutting: 665–630 or 625–520 BC.
The theories underlying all three methods are discussed in this paper and a comparison made for the fitting of specific model sequences.
All three methods are found to give consistent results and the application of any one of them depends on the nature of the scientific question being addressed.
One way around this limitation is through comparison of time-series, which should exhibit the same irregular patterning as the calibration curve.
