There are multiple literary devices found within the lines of John Donne's poem "The Sun Rising."
Personification- The giving of human characteristics or abilities to nonhuman/nonliving things.
In line one of the poem, the sun is personified.
BUSY old fool, unruly Sun.
Here, the sun is given the ability to be a fool and unruly.
Metaphor- A comparison made between two typically unlike things (not using "like" or "as").
The first line is also a metaphor. The sun is being compared to an "old fool."
Alliteration- This is the repetition of a consonant sound within a line of poetry.
The second, third and fourth lines of the poem contain alliteration.
Why dost thou thus,
Through windows, and through curtains, call on us?
Must to thy motions lovers' seasons run?
In the second line, the "t" sound is repeated in "thou" and "thus." The third lines has two examples of alliteration: the "t" in both of the times "through" is used and the "c" in "curtains" and "calls." In the fourth line, "m" is repeated (in "must" and "motion").
These three literary devices are repeated over the course of the poem.
