[[caption-width-right:212:The modern Iron Age family.]]
This animated series from HannaBarbera is about a DomCom family in "ancient" Rome. As on ''WesternAnimation/TheFlintstones'', AnachronismStew is an essential part of this series--but the starting point is later.
The head of the family is Augustus Holiday. He has a wife, Laurie; a daughter, Precocia, and a son, Happius, or "Happy"/"Hap" for short—much like ''WesternAnimation/TheJetsons'' (although unlike that show, this family features an older brother and younger sister). Their pet lion, Brutus, is a BigEater.
* CanisLatinicus: It mostly ties in to the Meaningful Names of the characters.
* ComicBookAdaptation: Four issues were published by GoldKeyComics (February–November 1973). The first three were drawn by Pete Alvarado; the final issue was drawn by Jack Manning.
* HeyItsThatVoice: Creator/DawsButler as Brutus [[note]]What's more, he uses his Snagglepuss voice[[/note]] and Creator/DomDeLuise as Gus' landlord, Mr. Evictus. Gus himself is voiced by the ''WesternAnimation/WackyRaces'' announcer.
* IncrediblyLamePun: All over the place.
* MeaningfulName: Their landlord is named Evictus, and Gus' boss at the marble quarry ([[WesternAnimation/TheFlintstones déjà vu?]]) is Tycoonius.
* PantyShot: Precocia in "Hectic Holiday." More a case of innocent panties.
* PunnyName: See the above.
* ShoutOut: The title is a pun on the film ''Film/RomanHoliday''.
* SingleIssueLandlord: Evictus is determined to prove that the Holidays are keeping a lion in their apartment building (the "Venus De Milo Arms").
* ThemeParkVersion: Of the Roman Empire.
