Here are some of the most significant ones:
* "Dover Beach" by Matthew Arnold: This is the poem that truly sparks Montag's desire for knowledge and change. He reads it to Mildred and her friends, who are completely unmoved and even angered by it.
* "The Sea of Faith" by Matthew Arnold: This poem is a continuation of "Dover Beach" and is a part of the same collection of poems, but it was not mentioned by name in the novel.
* "The Tiger" by William Blake: This poem is the one Montag reads to Clarisse's uncle, the book-loving professor.
It's important to note that there is no single definitive "poem that Montag reads." The novel mentions these poems specifically, but other poems are alluded to or simply described. The poems serve as catalysts for Montag's intellectual awakening and his rebellion against the oppressive society.
