Last of the Romans
The term Last of the Romans () has historically been used to describe a person thought to embody the values of ancient Roman civilization – values which, by implication, became extinct on his death. It has been used to describe a number of individuals. The first recorded instance was Julius Caesar's description of Marcus Junius Brutus as the one with whom the old Roman spirit would become extinct.
