«Cupid laid by his brand, and fell asleep:
A maid of Dian’s this advantage found».
The last two sonnets, which may be considered as appendices to the preceding sonnet story, do not touch upon any of the major themes in the sonnets.
Cupid laid by his brand, and fell asleep:
In Sonnet 153, after Cupid, god of love, falls asleep, a “maid of Dian’s” steals Cupid’s “love-kindling fire” and extinguishes it in a golden valley’s fountain. As the fountain absorbs the heat from the fire, the water acts as a curative potion for “strange maladies” — for example, love sickness. However, the poet finds the best cure for his passion in his mistress’ eyes.

Summary from Cliffsnotes.com
Shakespeare’s sonnets explore a wide range of emotions and themes, from love and loss to time and mortality. Many of them are addressed to a mysterious young man, whom scholars have speculated was a real person or perhaps an idealized version of Shakespeare himself. Whatever their subject matter, Shakespeare’s sonnets are remarkable for their insight, beauty, and eloquence. It is no wonder that they have inspired poets for centuries.
