Graceland... Home to Elvis, The King! Grace means a gift from God. God is ever present and we are completely blind to it.
All the time people are looking for the Man behind the Myth. (meaning the author, I believe)
We should be looking for the Myth behind the Man. I suppose that this means that everyone has a story to reduce it to a cliche. I think that is very true. We all have some sort of a story and being the conceited creatures that we are we want everyone to know about and be enthralled by our story.
Pentheus
His name literally means a man of constant sorrow. This is so true!
Metaphor
To carry over from one to another. You are sort of giving something another's quality or likeness. It makes sense.

It appears when there is a huge gap between the crime and the punishment. The punishment is completely unjust or very questionable. When the Gods create a problem for someone they then punish them unjustly for not handling the situation the right way. It explains it more in the link above.
