**Paradise Lost** is an epic poem written by the English poet John Milton, first published in 1667. The poem is widely considered one of the greatest works in the English language and a cornerstone of English literature. Composed in blank verse, it consists of ten books in its original edition, which was later revised into twelve books in the 1674 edition. The poem explores the biblical story of the Fall of Man, depicting the rebellion of Satan against God, the temptation of Adam and Eve by Satan in the form of a serpent, and their eventual expulsion from the Garden of Eden. Central themes include obedience, free will, justice, and redemption. Milton aimed to "justify the ways of God to men," presenting a complex theological and philosophical exploration of sin and salvation. John Milton, who was blind by the time he composed Paradise Lost, dictated the poem to assistants. His deep knowledge of classical literature, theology, and contemporary politics informed his writing. The character of Satan is especially notable for his powerful rhetoric and tragic depth, sparking debate about heroism and morality in the poem. Paradise Lost has significantly influenced later writers, thinkers, and artists. Its impact extends beyond literature into fields such as theology, philosophy, and political theory, securing its place as a monumental achievement in world literature.
