How does Milton describe the content of his epic?

Book I of Paradise Lost begins with Milton describing what he intends to undertake with his epic: the story of Man's first disobedience and the "loss of Eden," subjects which have been "unattempted yet in prose or rhyme." His main objective, however, is to "justify the ways of God to men."
