Answer:
anaphora
Explanation:
Anaphora is a rhetorical element used in making emphasis in a speech, poems, or in novels. This rhetorical device involves the repetitive use of a word or phrase at the start of every successive line or sentence of a speech.
In the excerpt cited from "Song of Myself", the word "of" was used repeatedly, at the beginning of each successive line. This is an example of anaphora.
