Ophelia: "...<em>words of so sweet breath composed </em><em>as</em><em> made the things more rich..."</em>
Words such as "like" or "as" help the reader identify the use of this figurative speech.
In John Milton's Paradise Lost, both the fall of Adam and Eve and the fall of Satan and his cohorts are caused by disobedience to God.
