Sonnet 127 is the first of 26 poems in the 1609 collection which together are generally known as the Dark Lady Sonnets. While William Shakespeare himself never uses the expression 'Dark Lady' any more than he uses the term 'Fair Youth' in these sonnets, it is entirely clear from this sonnet onwards that this much shorter section concerns itself with a woman who has dark hair, dark eyes, and a complexion that is most likely tan or olive, as opposed to pale.
The sonnet sets a tone that is ambiguous, somewhat distanced, perhaps slightly ironic, perhaps also quite sincere, but neither of these in an obvious, let alone straightforward way, and it establishes from the outset that the person our poet is now talking about is his 'mistress', and that she does not fit the hitherto or until recently accepted ideal of beauty. In fact, she represents, so the sonnet tells us, the exact opposite of what used to be considered beautiful, but although Shakespeare does not exactly sound overjoyed at her kind of beauty being recognised, he still values this genuine, natural beauty above the cosmetic artifice that apparently has now become the fashion.

In this special episode, Sebastian Michael looks at the first 126 Sonnets in the 1609 collection and examines the principal questions they present:

- Is there a Fair Youth at all?

- If so, is this the same young man throughout, or could it be that the first 17 poems, the Procreation Sonnets, are addressed to someone else?

- And if there is a Fair Youth, who is it?

While there will most likely never be answers that can be offered with cast-iron certainty, a detailed analysis of the textual and external evidence we have does yield significant pointers and offers an idea as to where, on a scale of plausibility, we may locate them.

Sonnet 126 is the last poem in which William Shakespeare addresses his younger lover and so marks the end of the Fair Youth series in the collection first published in 1609.

The sonnet stands out for its tenderness and the gentle tone with which it reminds the young man that even he – beautiful as he is and ever youthful as he may seem – must ultimately be surrendered by nature to all-consuming time, and for the quiet resignation with which it accepts this as the universal and inescapable truth that is all our fate.
Beyond that, the poem is also formally exceptional: consisting as it does of six rhyming couplets, it isn't strictly speaking a sonnet at all, though either Shakespeare himself or somebody else has furnished it with two sets of empty brackets where a sonnet's closing couplet would normally be. And so Sonnet 126 is genuinely unique: there is none other in Shakespeare's canon like it.
