I was fascinated by the announcement of the 'virtual unrolling' of a fire-burned scroll in En-Gedi that has been analysed and found to be part of the book of Leviticus.
As the Guardian noted, the technique could be applied to the scrolls burned by Vesuvius in the 'villa of the papyri'.
Unfortunately, because of the quirks of time, the works of Appian and Tacitus won't be in the villa as it was destroyed before they wrote and published their works. But that got me wondering: which of their (lost or incomplete) sources could be in the villa?
The sources for Tacitus and Appian seem to be difficult to get into my head - I couldn't see anything on them particularly from a google search. Potentially, the histories of Polybius or Livy could be used, or the lost history of Claudius... either of which could turn up in the villa. But who else?
