How are the lines from The Dunciad that appear in the lesson a parody of Milton?

In "The Dunciad," Alexander Pope parodies John Milton's epic style and grand themes by mocking the notion of poetic greatness. Instead of celebrating a noble hero or divine inspiration, Pope presents a satirical portrayal of ignorance and mediocrity, contrasting Milton's elevated language with trivial subjects. By employing a similar epic structure, he highlights the absurdity of his characters and their pursuits, ultimately undermining the seriousness of Milton's work while critiquing the declining standards of contemporary literature. This juxtaposition serves to both honor and ridicule the epic tradition, showcasing Pope's wit and commentary on the state of poetry in his time.
