As set out in a previous post, when the Dead Sea Scrolls were discovered they were dated on palaeographical (handwriting) analysis before the time of King Herod (37 to 4 BCE) or at least not later than the earlier years of Herod — before 20 BCE. We saw in the same post how the various scripts were subsequently recalibrated so that they brought the Dead Sea Scrolls into line with the Jewish Revolt of the late 60c CE. The handwriting styles of the Dead Sea Scrolls were aligned so that many of them were fresh and hidden in caves around 68 CE.
But how valid are the dates assigned on those palaeographic script charts? Not all scholars accept that recalibration as the final word.
A first observation is that the small number of decades separating mid-first century CE from the time of Herod is barely greater than acknowledged margin of error, but that is not the important point.
The important point is the circularity in which scribal hands of texts from Qumran’s caves were defined after 1951 as dated as late as the first century CE because those defining the palaeographic sequences believed Qumran scroll deposits at the time of the First Revolt had been firmly established archaeologically. No information in the years since has materially altered this epistemological circularity. Radiocarbon dates on Qumran texts that have been done until now have not altered this picture.

It was believed that a script belonged to the time of the Jewish revolt (66-70 CE).
Therefore the script was formally dated in the chart to the time of the Jewish revolt.
And the chart thereby became the standard for dating the scripts.
