Satyricon (1969)

This is an imperfect-but-creditable Italian movie. Encolpio (Martin Potter) is lamenting the loss of his lover Gitone (Max Born) to Ascilto (Hiram Keller). Vowing to win him back, he learns that Ascilto sold Gitone to the actor Vernacchio. At the theatre, he discovers Vernacchio and Gitone performing in a lewd play. Encolpio storms the stage and reclaims Gitone. On their return to Encolpio's home, they walk through a vast Roman brothel. Captured by soldiers, Encolpio is released in a labyrinth and forced to play Theseus to a gladiator's Minotaur for the amusement of spectators at the festival of Momus, the God of Laughter.

The film is based on a Latin work of poetic fiction written in the first century by Gaius Petronius.
