I found this site that had one of these little quizzes. I usually ignore them because often they are just attempts to get your e-mail address and other contact information, but this one wasn't. It was just what it said it was. A little quiz. I took it and to my disappointment, I turned out to be Hermes. I was hoping for one of the big three, but no.
Take the quiz yourself and then come back here and leave a comment telling me which god or goddess you are!
