the chorus to "up the wolves" references the story of the founding of Rome by Romulus and Remus, fathered by Mars, whose mortal mother was lost to them in the classic "your kid will murder the king" storyline. as babies they were sent down the Tiber River and eventually came to shore and were adopted and cared for by a female wolf.
i feel like there are a ton more, but i think there are just so many little things, plot lines and subtle references that i hear often without being as evident as others.
historical and literal reference were biggest turn-ons for me when i first heard tmg.
