I know where you are. Go over to that hole in the wall with the gears, hit escape, go to your item inventory, and select Sophia's part and the elevator will come up. Pull or push the bull's block toward the brass door once, climb on top of it, and jump up to the edge. Watch for spiders and scorpions in the next room. Your objective is to find 3 different sets of cuniform tabliture, a big piece, a medium sized piece and a small piece. This is probably one of the easier big puzzles in the game. Hope this helps.
