雪莱一八二一年作。诗人呼唤夜之精灵踏浪而来，以长发遮住白昼的眼，以罂粟之杖抚过城郭山海。夜有兄曰死亡，有女曰睡眠，诗人却只求拥夜入怀。想象奇丽，音节流转。
Swiftly walk o’er the western wave,
Spirit of Night!
Out of the misty eastern cave,
Where, all the long and lone daylight,
Thou wovest dreams of joy and fear,
Which make thee terrible and dear,—
Swift be thy flight!
Wrap thy form in a mantle gray,
Star-inwrought!
Blind with thine hair the eyes of Day;
Kiss her until she be wearied out,
Then wander o’er city, and sea, and land,
Touching all with thine opiate wand—
Come, long-sought!
When I arose and saw the dawn,
I sighed for thee;
When light rode high, and the dew was gone,
And noon lay heavy on flower and tree,
And the weary Day turned to his rest,
Lingering like an unloved guest,
I sighed for thee.
Thy brother Death came, and cried,
Wouldst thou me?
Thy sweet child Sleep, the filmy-eyed,
Murmured like a noontide bee,
Shall I nestle near thy side?
Wouldst thou me?—And I replied,
No, not thee!
