Discuss John Dryden's use of the metrical contract in Absalom and Achitophel.

Hey Everyone,

I'm writing a paper on the ways in which Dryden use metrical variation within Absalom and Achitophel. I want to be specific and use examples, though I'm having a hard time deciding how to form my argument.

Does anyone have knowledge on how Dryden uses metrical variation?
Which lines are prominent examples, and why?
What effect does the metrical contract have on the poem?

Anything will help!

Thanks,
