In my lecture this weekend, I'll talk about Tolkien's poem "The Tale of Tinuviel." Here is a link to a recording of Tolkien reading that incomparable poem.
"The leaves were long, the grass was green,
The hemlock-umbels tall and fair,
And in the glade a light was seen
Of stars in shadow shimmering.
Tinuviel was dancing there
To music of a pipe unseen,
And light of stars was in her hair,
And in her raiment glimmering."
