Figure 2

(a) A picture of the PHerc.Paris. 4 lying in its transport holder, fabricated by means of a three-dimensional scan of the external papyrus shape profile (~16 cm length). The carbonized papyrus is extremely fragile. Its deformation was caused mechanically by the eruptive material; (b) three orthogonal slices, and (c) a volume rendition of the reconstructed papyrus, which highlights the huge complexity inside the scroll, where the papyrus convolutions were exposed to tremendous stresses.
