In Mission 31: The Ziggurat of MindsEye, you get the objectives to “Decipher the Pattern” and “Unlock the Statue’s Secret”. You will be in the catacombs underground and must spin a disc to align the symbols. Then you must place crystals around the room to redirect the light. Afterward you reach another puzzle room where you must solve the Statue’s Secret.
How to Decipher the Pattern
Spinning Disc:
Align the symbols as shown on the image below. Start from the outermost ring and work your way to the inner ring. You can use the right stick to spin the discs and left stick to select a disc.
Left Side Crystals:
After aligning the ring it will light up, then beams of light shine at crystals in the room. You must place the crystals in the correct order to open the chambers on the left and right. Inside the chambers, place the crystals so the light can reach the yellow dot at the end of the chambers.
Place the crystals as shown in the images below. Start with these 4 crystals on the left side of the room:
Left Chamber:
The left chamber will open after placing the crystals correctly. Inside the left chamber move the crystal from the back to the front.
Right Side Crystals:
On the right side of the room, place the 4 crystals as shown in image below:
Right Chamber:
In the right chamber, place 2 crystals so the light hits the yellow dot.
Then the door below the spinning disc opens and you can walk through, thus finishing the puzzle. After the next cutscene you unlock the Lesser Key of Solomon trophy/achievement.
How to Unlock the Statue’s Secret
A little bit later you come to another puzzle room with a spinning statue. You must interact with a console again, it will trigger the objective “Unlock the Statue’s Secret”.
To solve the Statue’s Secret, you must shine 4 beams of light on the statue’s head.
There are 4 yellow buttons around the statue. Hit the 4 buttons ONCE EACH with the light that comes from the statue’s hands. If you hit the same button again it will turn off. Use the left stick to raise/lower the statue’s arms and the right stick to change the direction in which the statue spins.
The trick is to make the statue spin in the opposite direction before it hits the same buttons again.
Here’s what the statue looks like when the puzzle is solved (4 lights on its head):
Completing this puzzle also unlocks the Xenoarchaeologist trophy/achievement.
