All of those are very interesting, Elaini -- thanks!
That last one struck me as very like the Isadora Duncan style.
You do make a good point on the "lightness" of the
Elves --
Legolas running atop the snow of Caradhras certainly brings that home!
One caveat I'd register is that, as Kinofnerdanel's OP underlined,
Luthien's dance was inspired by Edith's; although her dance would doubtless have been lighter, and more "idealized" in
Tolkien's conception, still it was based on a real-world event. And that, I
think, is what she was asking about (though I'm open to correction -- she hasn't been about lately -- hope she returns soon!).
That, anyway, is what led me to suggest Isadora Duncan as a "real-world" possibility. Though I could be wrong.
Despite the more restrained examples you give, I have to say I remain skeptical that Edith would have been performing anything close to a belly dance!
