She walks in beauty, like the night
Of cloudless climes and starry skies;
And all that’s best of dark and bright
Meet in her aspect and her eyes:
Thus mellow’d to that tender light
Which heaven to gaudy day denies.

George Gordon, Lord Byron (1788-1824) English poet

“She Walks in Beauty,” st. 1 (1814), Hebrew Melodies (1815)
