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.
