Oh and and on a side note, I just noticed a mistake in the Perez panels.
Perez's Amazon's couldn't have had a Coliseum. The Coliseum (Colosseum) is a Roman structure that was created way after the Greek Golden Age. They would never have seen it to copy it. Even if they had, Coliseum refers to size. There is no reason for the Amazons, who only numbered a few thousand, to have a structure that would house more than the (stable) population of the island. Lastly, Colosseum is the latinization of the greek Kollosos. So the Amazons would have had a Kolloseum or more correctly a Stadium or Hippodrome.
