How to position the symbols the right way?
From this walkthrough:
Get each symbol to its position according to the Journal:
Eagle should be on Bottom row, middle square. Horse should be on Second from bottom row, leftmost square.
For the other two symbols, locate the reflective floor symbols around the room. Look how the light from your torch is reflecting on the floor there. The symbol changes depending on where you're standing. Use that to figure out where the other symbols should go. The solution is:
Bull should be on middle row, fourth square (from the left) Lion should be on fourth row from bottom, second square from left.
