Ezra Pound - "Fair Helena" by Rackham lyrics

"What I love best in all the world?" When the purple twilight is unbound, To watch her slow, tall grace and its wistful loveliness, And to know her face is in the shadow there, Just by two stars beneath that cloud— The soft, dim cloud of her hair, And to think my voice can reach to her As but the rumour of some tree-bound stream, Heard just beyond the forest's edge, Until she all forgets I am, And knows of me Naught but my dream's felicity.
