[1] The musical setting, previously attributed to Henry Purcell, and probably for the London revival of 1712, was very probably by John Weldon.
[2] The Dryden–D’Avenant adaptation premiered at the Duke's Theatre in Lincoln's Inn Fields, London, on 7 November 1667, and published in 1670.
This was the version of The Tempest most familiar to audiences up until William Macready's enormously successful production of Shakespeare's original on 13 October 1838.
Dryden and D'Avenant keep a great deal of Shakespeare's verse, but generally tone the play down, simplifying grammar and language occasionally, removing much of the "mythic resonance" of the original, and adding a fair amount of their own invention.
The added elements include new characters – Hippolito, a man who has never seen a woman, and Dorinda, a second daughter of Prospero.
