Continue ahead and take out the insects. You can also destroy their nests for some extra orbs. Climb the ox statue and make your way to the aqueduct. Turn left immediately to find two red Chests
and a Gorgon Eye chest at the end.
Follow the aqueduct until a part of it crumbles. Continue forth and you'll have to slide down then press X to jump and R1 to grab hold of the glowing green object and swing to the tower ahead. Climb up the tower until you make it to the next part of the aqueduct.
You'll eventually reach a blue gate. Take the Ice of Poseidon to learn a new magic. This ability will allow you to break blocks, breath underwater and freeze enemies so they yield large, red orbs. Kill all enemies using your new ability to open the gate.
Continue past the gate and follow the path until you reach three Chests
. One of them contains a Gorgon Eye right in full view.
Jump down to the snake-like machine and pull the ring apart to make it move. After the scene, grab hold of the glowing part of the tower and climb up to enter it.
