The musical A Funny Thing Happened On The Way To The Forum opens with the song Comedy Tonight.
The lyrics describe how the show is a comedy, and not a tragedy. The show will not contain various elements common in Greek or Roman tragedies.
Nothing for Kings, nothing for crowns
Bring on the lovers, liars and clowns
Old situations, New complications,
Nothing portentous or polite;
Tragedy tomorrow,Comedy tonight!
Nothing with gods, nothing with fate;
Weighty affairs will just have to wait!
Nothing that's grim. Nothing that's Greek.
She plays Medea later this week.
No Royal curse, no Trojan Horse,
And there's a happy ending of course
What does "polite" mean in this context?
The most common definitions don't really match the other things that explicitly aren't in the play. I don't think it means that everyone is rude.
My best guess is that it means "political" but that isn't a proper meaning of the word. Polite comes from the same root as polished, while politics comes from polis, meaning city. No connection between the two.
