Greco-Roman culture was defined by the transmission of educational foundations throughout lands ruled by Greece and Rome. Literary works provide overwhelming evidence of a shared body of knowledge between the educated classes of the Greco-Roman era, as exemplified by hundreds of Greek papyrus volumes found in a Roman villa near Herculaneum. Romans frequently attended schools in Greece, as known from the lives of figures like Cicero and Julius Caesar, and the dual Latin and Greek inscriptions of Augustus's Res Gestae demonstrated official recognition of the common Greco-Roman culture.
