Spartacus
Banned
Yes, Spartacus would probably be employee'd by the Sumerian's as a Nay-Sayer. They were actually highly sought after and respected individuals in that society.
And since I was adopted into an American Indian family lets not forget the Heyoka:
http://en.wikipedia.org/wiki/Heyoka
"Their satire presents important questions by fooling around. They ask difficult questions, and say things others are too afraid to say. By reading between the lines, the audience is able to think about things not usually thought about, or to look at things in a different way."
