Here you will find the Poem The Elves of poet Denise Levertov
Elves are no smaller than men, and walk as men do, in this world, but with more grace than most, and are not immortal. Their beauty sets them aside from other men and from women unless a woman has that cold fire in her called poet: with that she may see them and by its light they know her and are not afraid and silver tongues of love flicker between them.
