In the first poem, "the sunrising" talks about a man that just get up and he is with his wife, or lover , and he is happy because he just woke up with her, but the sun , is making him move and start a new day, thing that he doesn't want, because he wants to stay with her. After that he starts to caompare her with the sun, so that he makes it feel "smaller" located in the verses 15-16; also he is trying to make her feel something bigger someone that is something more, in ypour life, located in the verses 21-22.
O the other hand, in "the canonization" it is a poem where he is kind of angry or upset because he might have met a woman that is worth to love, but she doesn't let him love her, and he wrote this, so he shows her that is worth to love her. In this case, he compares her to everything that is amazing, that make her feel beautiful and important; one example of it is the verse 1-2 and the verses 44-45.
Some of the themes that he uses, is the religion and he uses it to make feel someone bigger and important, because his context was that religion was the best thing ever, and that God can be compared with you makes you something important. Another thing that he uses is power, refeing to the goverment, so that the reader feels the power, the kind of love that he has to her.
In the literary devises he mainly uses the retoric questions, so that the reader, or the person that the poem is for, understand, and asks him or herself the real reason why he or she feels that way, and if it is worth to. In "sunrising" he uses a zeugma to make that the sentence, has to meanings, or he uses a chiasmus to make her feel that the realitionship is the biigest thing.
In conclusion, he uses the themes and litery devises to make the ideas change from something simple, to the best thing that could have happened to the person that the poem is for, and also to change the ideas of the person that the poem is for, because this could make the chane of saying with her or not.
