This document provides a character study of Adam, Eve, and Satan from John Milton's epic poem "Paradise Lost Book IX". It summarizes that Eve is created from Adam's rib to be his companion, and that she is more physically attractive but less intellectually strong than Adam. It notes that Satan tempts Eve by exploiting her vanity, convincing her to eat the forbidden fruit first before convincing Adam. It describes Adam as the first man, strong but weak in logic, who eats the fruit to avoid losing Eve. Satan is introduced as the former angel Lucifer, who was thrown from heaven due to his envy and now seeks to damage human happiness out of revenge against God.
