He disguises himself as a serpent, then convinces Eve to eat the fruit of knowledge-an act that results in her and Adam being banished from paradise. Paradise Lost summary key points: God identifies Satan to the Son and explains that Satan will lead Man to Sin. The Son volunteers to sacrifice himself in return for God's divine grace for Man. Satan disguises himself as a bird and tempts Eve by whispering in her ear as she sleeps.
