Unlocking the scrolls of Herculaneum....

For centuries scholars have been hunting for the lost works of ancient Greek and Latin literature. In the Renaissance, books were found in monastic libraries. In the late 19th Century papyrus scrolls were found in the sands of Egypt. But only in Herculaneum in southern Italy has an entire library from the ancient Mediterranean been discovered in situ.
It was also a place where Rome's richest engaged in a bit of cultural one-upmanship - none more so than Lucius Calpurnius Piso Caesoninus, a politician and father-in-law of Julius Caesar.
In Herculaneum, Piso built a seaside villa on a palatial scale - the width of its beach frontage alone exceeds 220m (721ft). When it was excavated in the middle of the 18th Century, it was found to hold more than 80 bronze and marble statues of the highest quality, including one of Pan having sex with a goat.
A blast of furnace-like gas from the volcano at 400C (752F) carbonised the papyrus scrolls, before the town was buried in a fine volcanic ash which later cooled and solidified into rock.
When excavators and treasure hunters set about exploring the villa in the 18th Century, they mistook the scrolls for lumps of charcoal and burnt logs. Some were used as torches or thrown on to the fire.
