The glitt'ring colours of the day are fled;
Come, melancholy orb! that dwell'st with night,
Come! and o'er earth thy wand'ring lustre shed,
Thy deepest shadow, and thy softest light;
To me congenial is the gloomy grove,
When with faint light the sloping uplands shine;
That gloom, those pensive rays alike I love,
Whose sadness seems in sympathy with mine!
But most for this, pale orb! thy beams are dear,
For this, benignant orb! I hail thee most:
That while I pour the unavailing tear,
And mourn that hope to me in youth is lost,
Thy light can visionary thoughts impart,
And lead the Muse to soothe a suff'ring heart.

Helen Maria Williams
