Milton pointed out at the beginning of the poem that the purpose of Paradise Lost is to prove that "God's behavior towards people is correct". However, the image of God in poetry is not so lovely. What he wants is absolute obedience, which seems arbitrary and arbitrary. It seems unreasonable to foresee that man will fall, but at the same time, he fasted the fruit of wisdom. Compared with the abstract, gloomy and distant God, the image of Satan is concrete and credible. At first glance, Satan is the enemy of God, scheming, and the embodiment of evil in poetry. However, gradually, readers will find that Satan actually pursues freedom, doubts God's rule and challenges God's authority. After Satan was sent to hell by lightning, he and other rebellious angels suffered in the sea of fire and still showed high fighting spirit. He said, "What's terrible about failure on the battlefield? My unconquerable will, my determination to retaliate, my gnashing hatred, and my ambition to never bow. " Perseverance, persistence in struggle and opposition to God are quite like Milton in the revolutionary period. Because Milton, like Satan, is a rebel who challenges authority, and both rebels seem to end in failure. Satan in the works is a rebel who dares to resist God's authority and autocratic rule, and also a symbol of British bourgeois revolutionaries. This long poem also discusses the reasons for the failure of the British revolution and human misfortune.
Paradise Lost inherits the epic tradition of ancient Greece and Rome in structure, and describes various magnificent scenes of heaven and hell, chaos and human beings. For example, when describing the war in the kingdom of heaven, Satan invented gunpowder and used a row of guns to make the heavenly soldiers and generals flustered. This scene is very spectacular and strange. Allusions in poetry are all-encompassing, both ancient and modern, at home and abroad. Long poems are plain, and the combination of concise English and classical Latin has made a "solemn and lofty style". Paradise Lost is sonorous, vigorous, grand and magnificent. It is a masterpiece of English poetry in the17th century and a grand epic of British bourgeois revolution.
