(AGI) Rome, Jul 13 - The most ancient lemon in the Mediterranean was found in the Roman Forum, dating back to circa 14 AD. It was discovered in the Tullianum prison - also known as St. Peter's prison - during an excavation campaign which brought to light new parts of the prison. The fruit, which originates in Asia, was found with fresh pulp and seeds. "It was part of a votive offering together with other fruits," explained archaeologist Patrizia Fortini, director of the campaign. "It is the first archaeological proof of lemon in the Mediterranean. Through radiocarbon analysis it was dated to 14 AD, pushing it back to a time much earlier than originally thought that lemons arrived here from Asia." The remains of the lemon are on display in the museum area of the prison, which will be open to the public on July 21 (reservation at www.orp.org). (AGI). .
