Sonnet 154 brings to a close William Shakespeare's collection of sonnets, and it does so hand-in-hand with Sonnet 153, of which it is not a continuation, but a reiteration.

Like Sonnet 153, the poem borrows directly from an epigram by 6th century Greek poet Marianus Scholasticus, and tells the story of Cupid who falls asleep in a mountain grove with his Torch of Hymen by his side. One of the goddess Diana's nymphs – in this version the most beautiful of them all – takes the torch and attempts to extinguish it in a nearby well, and in doing so inadvertently creates a hot bath for eternity.

In both versions by William Shakespeare, this becomes a place where men may go to find relief for their sickness or disease, whereby neither of the two sonnets specifies just exactly what kind of disease may be so cured and leaves it somewhat open to interpretation whether Shakespeare means merely the affliction of a love sickness, or whether he is also alluding, as is widely believed, to venereal diseases, most particularly syphilis, for which hot baths were considered to be a remedial measure, if not exactly cure, at the time.

Sonnet 153 is the first of two poems that round off the collection, both retelling the same story of a tired love god Cupid who falls asleep, having put down his torch beside him. This is taken up by a nymph who dips it in a cool fountain or well with the intention of 'disarming' Cupid, but the flame of the torch is so intense that it turns the pool into a hot bath where ever since men who are sick can go to find relief.

In this special episode, Sebastian Michael summarises the second part of The Sonnets by William Shakespeare in the 1609 collection and examines the questions they present in parallel to those posed by the Fair Youth Sonnets:

- Is there a Dark Lady at all?

- If so, who is it?

- And what, if anything, do these sonnets tell us about the poet himself, irrespective of who she is?
