An epic blank-verse poem in ten books dramatizes the cosmic origins and consequences of human disobedience, opening with a defiant fallen angel who rallies other rebels, depicts the cataclysmic war in Heaven and the horrors of Hell, traces the creation and innocence of the first humans, and follows their temptation and expulsion from paradise. Through narrative episodes, theological speeches, and visionary description it examines free will, obedience, authority, repentance, and God’s justice and mercy, balancing grand rhetorical language with psychological insight into pride, remorse, and hope, and presenting the fall as both personal tragedy and metaphysical event.
