I was reading the wiki page on Shelley's "Ode to the West Wind" earlier today. Interesting stuff.
In the second stanza of the poem, Shelley likens the chaos in the sky to a fierce Maenad.

Maenad. Maenad. I've heard that somewhere before.

Ah, yes. Maenads were the worshippers of Dionysus, the Greek God of wine and parties. The wikipedia page on them gives a detailed description, but meh, whatever. I'll break it down for ya.
Maenads were basically frenzied female hardcore ravers tripping on super-strong hallucinogens.


There.

The picture of a Maenad on wikipedia looks familiar.

So i thought and i thought and i thought, and i finally came to the conclusion that:
Maenads look like Disco Stu from The Simpsons.
