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.
One shade the more, one ray the less,
Had half impair'd the nameless grace
Which waves in every raven tress,
Or softly lightens o'er her face;
Where thoughts serenely sweet express,
How pure, how dear their dwelling-place.
And on that cheek, and o'er that brow,
So soft, so calm, yet eloquent,
The smiles that win, the tints that glow,,
But tell of days in goodness spent,
A mind at peace with all below,
This line could have two meanings: 
 
 Along with the previous line, it could be referring to the lights reflecting on her cheek and forehead. 
 It could also be describing her personality and intelligence and ability to speak well. 
 
 Women at the time would have been valued only for passivity and external beauty, but the poet’s feelings go beyond this, given that this woman is both intelligent and beautiful. 
 This is another lyrically balanced line, with the emphatic repetition of ‘so’, the soft  alliterative  ’s’s and the satisfying triplet of adjectives.
She Walks in Beauty
