The decipherment of an ancient scroll has revealed where the Greek philosopher Plato is buried, Italian researchers suggest.

Graziano Ranocchia, a philosopher at the University of Pisa, and colleagues used artificial intelligence (AI) to decipher text preserved on charred pieces of papyrus recovered in Herculaneum, an ancient Roman town located near Pompeii, according to a translated statement from Italy’s National Research Council.

Like Pompeii, Herculaneum was destroyed in A.D. 79 when Mount Vesuvius erupted, cloaking the region in ash and pyroclastic flows.

One of the scrolls carbonized by the eruption includes the writings of Philodemus of Gadara (lived circa 110 to 30 B.C.), an Epicurean philosopher who studied in Athens and later lived in Italy. This text, known as the “History of the Academy,” details the academy that Plato founded in the fourth century B.C. and gives details about Plato’s life, including his burial place.

“Among the most important news, we read that Plato was buried in the garden reserved for him (a private area intended for the Platonic school) of the Academy in Athens, near the so-called Museion or sacellum sacred to the Muses,” researchers wrote in the statement. “Until now it was only known that he was buried generically in the Academy.”

The text also detailed how Plato was “sold into slavery” sometime between 404 and 399 B.C. (It was previously thought that this occurred in 387 B.C.)
