literature must reads

There are certain books and/or poems and/or plays in which lay the roots of numerous literary allusions, satirical jokes, common sayings etc.. If a person hasn’t read them, then they’re really not getting the joke, so to speak. I’m trying to think of the top literary works that would fit this category.

So far I’ve thought of:

- The complete works of Shakespeare
- The Odyssey
- Gulliver’s Travels
- A Tale of Two Cities and Oliver Twist
- Oedipus
- The Canterbury Tales
- The Bible
- Alice in Wonderland
- The complete works of the brother’s Grimm, and Hans Christian Anderson in their original form
- Aesop’s Fables
- Paradise Lost
- The Divine Comedy

I’m leaving tons and tons and tons of stuff out. Which obvious ones have I failed to include?
