If your picked up the season pass for Assassin’s Creed Odyssey, you get access to bonus mission called The Secrets of Greece.  This mission takes place further into the main story (around the level 18 mark), and rewards you with coin, XP, and gear for completing. To get you through this bonus mission, I’ve put together this The Secrets of Greece guide. Let’s begin.

When Does The Secrets of Greece Mission Unlock?

After you complete the story mission, The Big Break, you will unlock The Secrets of Greece mission.

Before getting to the meat of this guide, let’s answer the first question on your mind. When does The Secrets of Greece Mission unlock? The Secrets of Greece mission unlocks after you complete the main story mission The Big Break. Once you’ve completed this mission The Secrets of Greece mission will become available. The Secrets of Greece mission has a recommended level of 18, so you will need to progress a ways into the game. Here’s the official description of The Secrets of Greece:

Demokritos, the “laughing philosopher,” fumbled his way into learning the whereabouts of three theorems. Combined, they’d unlock some great mystery, but first they’d need to be retrieved.”

Objective 1: Talk to Demokritos

Once you feel like you are well levelled, you may want to start The Secrets of Greece mission. To do this, make your way to Patrai in Achaia. In the city you want to talk to a man named Demokritos. You will find Demokritos by the Shipyard in beside a half finished ship. Speak with him to start your mission.

When you talk with Demokritos, he will talk with you about three divine mathematical discoveries (theorems). By collecting all 3 theorems, Demokritos will be able to unlock the secrets of the universe and reward you handsomely for you efforts. The 3 theorems he wants are:

  • Zeno’s Paradox.
  • Golden Ratio.
  • Pythagorean Theorem.

Let’s get all 3 theorems.

Objective 2: Locate and Collect the theorems

Now that we know what Demokritos wants, it’s time to gather the 3 theorems for him. I will show you the locations of each theorem below.

Zeno’s Paradox

The first theorem we will grab is the Zeno’s Paradox. This theorem can be found near the shore of Lokris. Lokris is directly east of Phokis. Head to that area now and make your way to the north coastline and the town of Alponos (see map). In Alponos  make your way to the shrine on the hill to the west of town. Inside the shrine is the Zeno’s Paradox.

Golden Ratio

To get the Golden Ratio, make your way to the city of Argos in Argolis. Once at Argos, make your way to Polykleitos’s Workshop. On a bench inside you will find the Golden Ratio.

Pythagorean Theorem

The final theorem we are going to grab is the Pythagorean Theorem. This theorem is bit trickier than the last two and requires taking you ship out on the seas. Once you have your ship, head to the islands of Thera, Paros and Anaphi. To the north of these three islands you will find the underwater Palace of Amphitrite. In the center of this dive site you will find the Pythagorean Theorem in a lootable box. WATCH OUT FOR SHARKS DURING THIS DIVE.

Objective 3: Return to Demokritos

When you have all three theorems, return to Demokritos.

Now that we have all three theorems, it is time to return to Demokritos. When you speak to Demokritos he will give you a bit of information on each theorem. Demokritos will then tell you about his final theorem which has to do with the universe. This theorem has to do with impressing a girl. This will trigger the Another Kind of Poetry mission. For completing The Secret of Greece you receive:

  • XP.
  • 315 Drachmae.

The real rewards are gained by completing the much higher levelled Another Kind of Poetry Mission.
