I know I sound like I'm asking you more questions but the information you're looking for is in both poems, you just need to begin extracting it. If you can answer these questions even at a base level then you have begun to extract and understand the poems.
If it'll be useful to you, you can put the answes you come up with on here and if you need it I'll help you arrange your ideas and see if you can come to a conclusion. Good luck.
