i am currently doing some research on the history of poetry and i found that it might even be older then literature it self.  "In prehistoric and ancient societies, poetry was used as a way to record cultural events or tell stories"(http://www.poemofquotes.com/articles/history-poetry.php). The oldest poem is "Epic of Gilgamesh" it is a story about a king. This site has a lot of information about the history and i think i just figured out what i am going to write my reashech paper on and its going to be greek poetry.
