Weary with toil, I haste me to my bed,
The dear repose for limbs with travel tired;
But then begins a journey in my head
To work my mind, when body's work's expired:
For then my thoughts--from far where I abide--
Intend a zealous pilgrimage to thee,
And keep my drooping eyelids open wide,
Looking on darkness which the blind do see:
Save that my soul's imaginary sight
Presents thy shadow to my sightless view,
Which, like a jewel hung in ghastly night,
Makes black night beauteous, and her old face new. Lo! thus, by day my limbs, by night my mind, For thee, and for myself, no quiet find.
Sonnet 27 is part of the Fair Youth sequence, in which the poet expresses his love towards another Woman. Sonnet 27, when written using modern spelling, is Shakespeare's only pangrammic sonnet. It forms a diptych with Sonnet 28 which continues it.
For another of Shakespeare's sonnets dealing with night, sleep and dreams see Sonnet 43.
