Revisiting the Jerash Silver Scroll: A new visual data analysis approach

Abstract

This article revisits a complexly folded silver scroll excavated in Jerash, Jordan, in 2014 that was digitally examined in 2015. In this article we apply, examine and discuss a new virtual unfolding technique that results in a clearer image of the scroll's 17 lines of writing. We also compare it to the earlier unfolding and discuss progress in general analytical tools. We publish the original and the new images as well as the unfolded volume data open access in order to make these available to researchers interested in optimising unfolding processes of various complexly folded materials.
