The Roman Holidays (1972)

The Roman Holidays is an animated television series that was broadcast in 1972. It ran for 13 episodes before being cancelled.  Very similar in theme to both The Flintstones and The Jetsons, The Roman Holidays brought a look at "modern-day" life in Ancient Rome. An Ancient Roman setting was actually one of the ideas that Hanna-Barbera considered as they were working to create The Flintstones.
