1. The purpose of repetition in Sonnet 73 is to make the reader think about Shakespeares point of view and how he would see things such as the yellow leaves hanging or the twilight of such day. Shakespeare is using Anaphora to get his point across and show imagery.
2. In the entire Sonnet, he uses extended metaphor. In lines 1-4 he uses personification. He is using personification when he speaks on how the birds sing as if they were in a choir. Then in lines 5-8 he uses antithesis when he says, “death’s second self, that seals up all in rest” which he is comparing death and rest to one another. In 9-12 he uses personification like when he compares his youth to ashes or his deathbed that is to expire.
3. In lines of 3-4 the placement of the birds on the branch(boughs) and a choir being a place and not only just a group of singer has something to do with one another. Then 7-8 relates to one another because death is suppose to be sealing up but in the next line he says that he has glowing of fire in him. If he was to die then the fire would not be glowing with in him.
