Once the Herculaneum vacation home of Julius Caesar's father-in-law, it is considered to be one of the most luxurious private homes in all of 1st-century Rome.
It also was home to an unusually large private library.
What happened?
The Vesuvius eruption (AD79) buried it in volcanic ash.
This carbonized many of the scrolls, and archeologists are now using technology to decipher them.
Mostly Epicurean tracts have been uncovered so far, but there is hope other lost philosophy works are there.
