its the first puzzle on the island you have to fly to after you get the pegasus back. There is a piece of teh floor that needs something with weight on it cause as soon as you step off the gate closes. I busted everything on both floors including those dead bodies and jars, but I don't see anything that can be moved.
oh yeah! you have to cut down all those corpes hanging from the chains, and then in the left hand corner there is a body that you take with you. that took me a while to figure it out, i kept trying to just run through the door
