Who wrote the declamation piece-vengeance?

There is no widely known declamation piece titled "Vengeance." Declamations are often original works or excerpts from literature, so it's difficult to pinpoint a single author without more information.

To find the author, you'll need to provide more context:

* What is the full title of the declamation?

* Where did you encounter this declamation? (e.g., school assignment, online resource, etc.)

* Do you remember any specific lines or themes from the piece?
