There are a ton of errors with this mod. Enough to cause my game to crash regularly, in fact.
I deleted the Dragon Circus text, which was causing a whole list of errors in of itself. Here is the log of what I have. It's probably something I did, but I didn't see a more descriptive installation readme, and I simply put the graphic in the graphics folder and the civ stuff in the objects folder.
