Keats

Keats seeks out the company of a common bird because it is nature. He puts it in the form of an ode because he feels as if he owes nature something, perhaps an apology before he passes away.

The content of the two stanzas(2 & 5) supports the claim because it talks about his wish before he dies, and the transition. "beaded bubbles" is an example of alliteration, and bubbles is an example of onomatopaeia. "Sunbirth mirth" is an example of assonance. "Blushful Hippocrene" is an example of allusion and personification.
