And don't overlook the links at the left under the words Horace and Resources.

And here's an good, simple definition of what satire is (and a satirist is simply a person who writes or draws in satire):

In addition ...

Here's a really good webpage on writing about literature; be sure to read all of it because the information covers how to set up such a paper, what to include, etc.
