Now I want
Spirits to enforce, art to enchant,
And my ending is despair,
Unless I be relieved by prayer,
Which pierces so that it assaults
Mercy itself and frees all faults.
-Prospero
The Tempest Epilogue, Line 15
This is Prospero talking at the end of The Tempest. It's the epilogue where he comes out to directly address the audience. There's an epilogue at the end of a half dozen or so of Will's plays. The only other one I'm familiar with is Rosalind talking at the end of As You Like It. And she and Prospero are saying pretty much the same thing: I hope you liked the show!
