With Sonnet 111, William Shakespeare shifts focus from his infidelities in relation to his younger lover, addressed in the previous two sonnets, to a general deficiency in his reputation, which he blames squarely on the fact that his circumstances require him to earn a living in the public sphere.

This, he claims, has led him to acquire the conduct of a person who attracts opprobrium, and while proposing to subject himself to whatever 'medicine' or 'penance' may be required of him, he sees and seeks his remedy first and foremost in the younger man's pity. This, he assures him, will suffice to cure him of any ills he may suffer resulting from any such misdeeds as come with the lifestyle his fortunes have imposed on him.

With his exceptionally candid and forthright Sonnet 110, William Shakespeare at once completes his apotheosis of his young lover, while at the same time confessing to him that yes, he too has had affairs with other people, but also reassuring him that these other lovers were no match for him and that they pale, compared to him, into insignificance, seeing that he is as "a god in love" to whom our poet feels and here declares himself to be inseparably tied.

Sonnet 109 is the first of two truly remarkable sonnets that speak of William Shakespeare's own infidelities towards his young lover during a period of prolonged absence.

Although they do not form a strictly tied pair, together these two poems position our poet and his relationship in an entirely new light, because they for the first time genuinely acknowledge that he, too, like his young lover, has succumbed to temptation elsewhere while they were apart, but they both affirm him to be the only one who ever mattered and the one who truly matters now.

With Sonnet 108, William Shakespeare loops back into sentiments expressed intermittently since Sonnet 76, but particularly again recently in Sonnet 105: I have essentially said it all, there is nothing I can do other than repeat and reiterate and rephrase the praises I have sung and continue to sing for you. What it also picks up from Sonnet 105 is the religious tone this set with a there still fairly oblique reference to the Holy Trinity. This was already amplified, though subtly, in Sonnet 106, and here finds a whole new level of what may potentially be perceived as impudence, if looked on from a devoutly religious perspective.
What it also does – and this may in some respects for our observation be most directly relevant – is to tell his young lover yet again that he is showing signs of age, but that to him, Shakespeare, this doesn't matter.

Of all the poems in the collection first published in 1609, Sonnet 107 most clearly and most compellingly seems to refer to external events that shape Shakespeare's world.

Because of this, it takes up a pivotal position in the canon, since it may therein hold clues to both its date of composition and to the person it is addressed to. And while there is little doubt in most people's mind that its references are indeed intentional and allude to some momentous occasion that has passed off signally better than anyone at the time would have predicted, and that in the ensuing calm and peace our poet feels that his love and his poetry have been given a new lease of life, no-one can tell with absolute certainty just what Shakespeare is actually referring to or whom he is talking to, or even whether the two factors are directly or only indirectly linked, or not at all.

There are, however, significant clues, and so much of our discussion of this sonnet will concern itself with what these are and what they mean for our reading of this and the other sonnets in the series.

Sonnet 106 sees Shakespeare return to eulogising his young lover in outwardly straightforward terms. And rather than looking ahead to times to come when his poetry will continue to pay tribute to his love long after both he and his lover have gone, as several of the other sonnets have done, he here casts his eye back to the past through the lens of the poets who have talked about the people of their day, and comes to the conclusion that they were doing just as he is doing now: trying to express the epitome of beauty. But since this had not yet been reached, because the young man of his love had not yet been born, they ended up not so much chronicling their age as predicting an age to come with his appearance in this world; and yet of course now that he is here, it is possible for Shakespeare and anyone who shares the privilege of being in his presence to admire him, but Shakespeare and his contemporaries still find it impossible to do him justice with their words.

Sonnet 105 presents a playful paradox that is no doubt fully intended on William Shakespeare's part.

Addressing, for a change, not his young lover directly, but speaking to the world in general about him and about his love for him, he tells us that we should not see, and in seeing so by implication judge, this love as the worship of a human and therefore by necessity false god, and then proceeds to deify this same object of his love in terms that – in a culture of immensely powerful religious strictures – comes scandalously close to sacrilege by effectively calling him 'the one and only' and investing him with qualities that prompt immediate comparisons to the holy Trinity.

With his celebrated and much-debated Sonnet 104, William Shakespeare appears to set out to do primarily three things: first and foremost, to reassure his young lover that even now, after some appreciable time has passed since they first met, he, the young lover, is still as beautiful to him, our poet, as he was on the very first day; in other words that for him, Shakespeare, the fact that his young lover may be showing signs not so much perhaps of age as of having grown up, doesn't matter.

Secondly, to alert the reader and listener – most particularly the reader and listener of the future – to our mortality and to the passing of time and to the fading nature of youth and beauty, even if the changes inflicted by time are not perceptible in the moment.

And thirdly – as it turns out for some people today still most controversially – to offer a time frame for the relationship with his young man of precisely and specifically three years. All of which, and particularly of course the latter, we will discuss in this episode.
