Dido and Aeneas, Z. 626: Epilogue: “All that we know the angels do above”

Epilogue to Dido and Aeneas – written by Thomas D’Urfey (first published in his “New Poems” of 1690)

“All that we know the angels do above,
I’ve read, is that they sing and that they love,
The vocal part we have tonight perform’d
And if by love our hearts not yet are warm’d
Great Providence has still more bounteous been
To save us from those grand deceivers, men.”

Just like the sung Prologue (libretto / image of first page of the printed programme of the opera's supposed premiere at Josias Priest’s boarding school ca. 1689, via nytimes article below) that is performed before the story of Dido and Aeneas begins, this spoken Epilogue has nothing to do with Dido’s tale, and hence is not part of its libretto. see http://www.bemf.org/media/BEMF_dido_blinarticle.pdf;
