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.

She Walks in Beauty, st. 1. The subject of these lines was Mrs. R. Wilmot.—Berry Memoirs, vol. iii. p. 7 - Hebrew Melodies (1815)
