Ok right after you get done defeating madusa for the first time and get to the ladder,go up the ladder and you will pass a guy haniging on a pole(by the way if you jump back towards the guy there is a red orb box with a lot of orbs on it.)once you get up the ladder you will see a lever.but instead of using it go passed it and strait to the bow.use it to break through the wall and there will be a box containing a gorgons eye.
