Exciting New Archeological Technique - X-Rays + "AI" Decipher Roasted Herculaneum Scrolls

First passages of Herculaneum scroll are DECIPHERED by AI: Students
use program to read more than 2,000 words on charred papyrus buried
by Mount Vesuvius eruption in 79AD

Students have deciphered a Herculaneum scroll using artificial
intelligence

. . .

   The first one wasn't THAT exciting ... seemed to have been
   writ by a nit-picking "philosopher" attempting to exactly
   define "pleasure". Included a diss of his fellow less-exact
   contemporaries ....

   BUT - there are lots of other scrolls.

   The scroll was 'carbonized' by the Vesuvius eruption
   of 79-AD. Just looks like a black stogie. Previous
   attempts to unroll them were a total fail.

   The ability of modern X-ray techniques to image
   individual, very thin, layers was a major plus.
   The "AI" was trained to cope with minor overlaps
   in the scans and discover real, logical, wording
   from the mess.

   It was common practice in the old days to write/paste
   over existing media. Said "media" were often expensive.
   That'd include papyrus, parchment and early forms
   of paper.

   Old stuff would be erased, or even further back a new
   layer of clay might be added or (as in Egypt) existing
   stuff largely hammered off to disappear some hated
   rival. However, at the very very fine level, traces
   of the original stuff may STILL remain. Even in stone,
   20/50/100+ years of weathering might leave a deeper
   imprint the eye cannot discern.
