Archaeologists in France have discovered dozens of Roman-era graves of men who were buried with “curse tablets,” at least one of which was written in an extinct language.

Excavations underneath an 18th-century hospital in the town of Orléans, about 75 miles (120 kilometers) southwest of Paris, have revealed more than 60 burials arranged in a single row along a wall. The cemetery, which dates from the end of the first century to the beginning of the third century, was atypical for this time because the burials were dug in a row, there were no women or children, there were traces of painted wooden coffins, and there were no cremations. This could mean that the dead were from a particular group, such as members of the same profession, according to the Orléans Archaeology Service, which excavated the site.
