I know there was an attempt by another composer (I think in the late 1800s/early 1900s?) to write a series of 3 operas based on Arthurian legend. But I think he only finished one before dying.

I love the lute! Much appreciate the Purcell rec!

EDIT
Just want to add that I always get a little giggle when I see contemporary costumes/staging paired with century specific music.
