However, today it has clearly emerged that the objects thought to be associated with Lucius Calpurnius Piso Caesonius correspond more closely to a greatly standardized assemblage, and cannot indicate, with certainty, the owner of the villa. The villa stretches down towards the sea in four terraces. Piso, a literate man who patronized poets and philosophers, built there a fine library, the only one to survive intact from antiquity. Scrolls from the villa are stored at the National Library, Naples. The scrolls are badly carbonized, but a large number have been unrolled, with varying degrees of success. Computer-enhanced multi-spectral imaging, in the infra-red range, helps make the ink legible. There is now a real prospect that it will be possible to read the unopened scrolls using X-rays. The same techniques could be applied to the scrolls waiting to be discovered in the as-yet unexcavated part of the villa, removing the need for potentially damaging the unrolled scrolls.
