You must use the floor switch at the top of the ramp in order to make the pedestal appear on the bridge. Take the Macalania Sphere off and push the pedestal onto the glyph. The glyph will push the pedestal into a destruction sphere. Use the Destruction Sphere in the underlevel of the Cloister in order to get this temple's treasure (a crappy luck sphere I think).

It is necessary to get each temple's Destruction Treasure in order to obtain one of the hidden Aeons.
