Frances Anne Kemble - Sonnet.

Thou who sitt'st listening to the midnight wind,
Pale maiden moon! 'tis said, that they who gaze
Too long upon thy melancholy light
Are struck with madness, and that o'er their mind
Thou shedd'st a mildew down, a withering blight.
If this were so, to some thy barren rays
Would be more welcome than the fruitful sun
To those who number none but happy days.
If to be mad were to forget one's grief,
Thy dewy finger-tips touching my brow
Might to my misery bring such relief
As misery such as mine can never know,
Till my distracted thoughts shall cease to run
From what once was—to all that must be now.

Frances Anne Kemble
