In a joint project of the Egypt Exploration Society and Brigham Young University Multi-Spectral Imaging (MSI)
technology was extremely successful in recovering previously illegible writing on several of the Oxyrhynchus Papyri.
With multi-spectral imaging, many pictures of the illegible papyrus are taken using different filters, finely tuned
to capture certain wavelengths of light. Thus, researchers can find the best part of the spectrum for distinguishing
ink from the writing material in order to recover illegible marks on damaged or rewritten papyri. Given that there are
over 500,000 papyri that survive from the Greco-Roman town of Oxyrhynchus in Egypt, the amount to be deciphered by this
technique is potentially enormous. In his lecture, Prof. Macfarlane estimated that 5-10% of the texts have features that
would lend themselves to enhancement or recovery by means of MSI.
