Iliad and its heroes

Iliad by Homer is very well known epic that we may hear at least once in our lives. As I read this epic, it was more like reading mythological stories unlike the first three literatures I read in class. It is interesting that the Gods and Goddesses play great roles in human society and have characteristics like human beings. By reading Iliad, we can find out how the war of Troy has developed and the conflict between the heroes although I was unclear that who is the main hero of the story, Achilles or Agamenmnon? Who is the good and bad? Iliad focuses on the war that lasted for 10 years. And it shows that how mistakes in the past can have great impact on future. It is a tragic story but tells interesting interpretation of human natures.
