What is the subject of Paradise Lost? What was its purpose?
Milton’s subject of his epic poem is indeed a lost paradise as the central theme of his work is to explain, defend, and vindicate God’s actions in dealing with succumbing to the temptation of Satan by Adam and Eve after they eat the forbidden fruit. Milton’s purpose was clearly to justify the ways of God in dealing with man, his creation. Here’s a very informative site you might like to puruse: http://www.cummingsstudyguides.
