National Anthem of Roman Empire (Instrumental)

(The Roman Empire didn't have official national flag and anthem)

In spite of the purported lack of musical originality on the part of the Romans, they did enjoy music greatly and used it for many activities.
Military music was used in parades, ceremonies and processions. Music was used to control troops on the battlefield. Music was also used in religious ceremonies, gladiator contests and events in the arena. The Romans cultivated music as a sign of education.

Roman-style musical instruments are found in parts of the Empire where they did not originate, and indicate that music was among the aspects of Roman culture that spread throughout the provinces.
