It is the purpose of this paper to study how Milton speaks in his poetry; especially, the poetic techniques in comparison with his poetry, "L`Allegro," "Il Penseroso," and "Lycidas." First, I will discuss the background and the characteristics of the two poems; the companion poems-"L`Allegro" and "Il Penseroso"-as philosophical poetry and "Lycidas" as a pastoral elegy in the tradition. Then, it will describe the differences of poetic techniques as independent poems; style, structure, tone and symbols, etc... Finally, I will discuss how Milton represents them as a vertical structure of one speaker. In the companion poems Milton describes his two conflicting states, while in "Lycidas" he can get a comfortable peace and a new poetic force in the end of the poem, which is a higher state of spiritual maturity. The whole structure of these three poems is a kind of `dialectical process` of a man from Earth to Heaven.
