Instructions
Walk up to either of the statues on the side of the door. Press "R2" to grab the statue. Pull it away from the wall and then get behind it.
Hold "R2" and press "X" to kick the statue off the ledge. Do the same for the statue on the other side of the door. The second statue lands on top of the one below it.
Jump down to the ground. Kick the statue across the courtyard, towards the left wall.
Push the statue against the wall below the highlighted ledge and directly across from a large stone structure.
Walk behind the stone structure and jump on the ledge. Jump from the ledge onto the stone structure and then jump onto the statue columns that you placed. Continue making your way up the path to reach the Oracle.
