Imaging technology reveals graffiti on a wall in Pompeii

A love note, a gladiatorial combat scene, a barrage of insults and everyday confessions have emerged on a wall in Pompeii. New imaging technology has revealed nearly 80 previously unseen inscriptions. After being covered in volcanic ash for 1,700 years, the site was rediscovered in the 18th century, and is now one of the world's most significant archaeological sites from the Roman Empire.
