The third tablet is in a room you will eventually get to by going through the third door from the revolving room. It has two matching corridors leading to two fountains. You need two crystals to open the doors to the fountains. Between the two corridors is a small alcove with a water filled passage below. By playing with the buttons(?) in the fountain rooms (you may need to move them twice) the alcove will open up and a ramp will emerge to reveal a chest with the third tablet. The chest shows up as a white dot with 'Spirit Eye'.
Hope that helps...
