Table 1: Cont. Because of the puzzling presence of several cubic dice with no writing marks or numbers, Raman chemical mapping and multispectral optical imaging were also used to image the unmarked surfaces in the attempt to check for eventual phantoms indicating residues of disappeared, degraded, or canceled signs. Surprisingly, no evidence whatsoever was found of labile or disappeared inscriptions, therefore supporting the pristine unmarked state of several of the cubic dice.
