Researchers at Cornell have used x-ray fluorescence to recover a number of illegible inscriptions, and apparently Draco’s laws are among them.
The article is found in ZPE 152 (2005): 221–227, ‘X-ray Fluorescence Recovers Writing from Ancient Inscriptions.’
Unfortunately our copy is currently in ‘labelling’ which means I may never see it. I’ll have to make do with short-on-content articles that feel the need to translate the names of publications.
(Zeitschrift fuer Papyrologie und Epigraphik is translated–Journal for Papyrology and Epigraphy–and given with no further citation other than ‘the August issue,’ so that lots of people who might want to read the article–and not the article about the article– might have a hard time finding it.)
