Sumerian Texts reference in FF XIII

I dont know if anyone else noticed but there are some references to the Sumerian Texts in FF XIII.

For example the bosses Enki and Enlil.

Also one of hopes weapons The Ninurta.

I found it to be very interesting.

   From an archaeological and historical standpoint FF games do AMAZING jobs in making references to ancient civilizations and cultures. I can't even begin to name them all. My fav is either reference to The Tale of Genji or the Mayan references from VIII. Being an archaeologist, this is one of my favorite aspects of FF games
