Analysis of Sonnet XX: Gracious Moonlight

Even as the moon grows queenlier in mid-space
When the sky darkens, and her cloud-rapt car
Thrills with intenser radiance from afar,—
So lambent, lady, beams thy sovereign grace
When the drear soul desires thee. Of that face
What shall be said,—which, like a governing star,
Gathers and garners from all things that are
Their silent penetrative loveliness?
O'er water-daisies and wild waifs of Spring,
There where the iris rears its gold-crowned sheaf
With flowering rush and sceptred arrow-leaf,
So have I marked Queen Dian, in bright ring
Of cloud above and wave below, take wing
And chase night's gloom, as thou the spirit's grief.
