This animated series from Hanna-Barbera is about a Dom Com family in "ancient" Rome. As on The Flintstones, Anachronism Stew is an essential part of this series—but the starting point is later. It aired only in the 1972-73 season on NBC.The head of the family is Augustus "Gus" Holiday. He has a wife, Laurie; a daughter, Precocia, and a son, Happius, or "Happy"/"Hap" for short—much like The Jetsons (although unlike that show, this family features an older brother and younger sister). Their pet lion, Brutus, is a Big Eater.
- Canis Latinicus: It mostly ties in to the Meaningful Names of the characters.
- Comic-Book Adaptation: Four issues were published by Gold Key Comics (February–November 1973). The first three were drawn by Pete Alvarado; the final issue was drawn by Jack Manning.
- Meaningful Name: Their landlord is named Evictus, and Gus' boss at the marble quarry (déjà vu?) is Tycoonius.
- Panty Shot: Precocia in "Hectic Holiday." More a case of innocent panties.
- Shout-Out: The title is a pun on the film Roman Holiday.
- Single-Issue Landlord: Evictus is determined to prove that the Holidays are keeping a lion in their apartment building (the "Venus De Milo Arms").
