Assassin’s Creed Odyssey: The Secrets of Greece Quest Guide & Rewards

If you purchased the Season Pass for Assassin’s Creed Odyssey, you gain access to a bonus mission called The Secrets of Greece. This quest takes place later in the game (around level 18) and rewards you with XP, Drachmae, and gear upon completion.

This guide walks you through how to unlock the quest, where to find the theorems, and what rewards you can expect.

How to Unlock The Secrets of Greece Quest

You unlock The Secrets of Greece after completing the story mission “The Big Break.”

Once you’ve finished The Big Break, the quest becomes available, but it’s recommended for level 18 or higher. If you try to complete it too early, enemies may be too strong.

Quest Description:

“Demokritos, the ‘laughing philosopher,’ believes he has uncovered the key to a great mystery. However, he needs help retrieving three ancient theorems—each one essential to unlocking his discovery.”

Step 1: Talk to Demokritos

Location: Patrai, Achaia

Travel to Patrai in the region of Achaia and find Demokritos near the Shipyard. He stands beside a half-finished ship. Speak with him to begin the quest.

What Does Demokritos Want?

Demokritos is searching for three legendary mathematical theorems that will help him uncover the “secrets of the universe.” He tasks you with retrieving:

1. Zeno’s Paradox
2. Golden Ratio
3. Pythagorean Theorem

Step 2: Locate & Collect the Theorems

Each theorem is located in a different region of Greece. Below are their exact locations and how to retrieve them.

Theorem #1: Zeno’s Paradox

📍 Location: Alponos, Lokris (east of Phokis)

• Head to the north coast of Lokris and find the town of Alponos.
• Just west of the town, look for a shrine on a hill.
• The Zeno’s Paradox is inside the shrine.

Theorem #2: Golden Ratio

📍 Location: Polykleitos’s Workshop, Argos (Argolis)

• Travel to Argos in Argolis.
• Inside Polykleitos’s Workshop, you’ll find the Golden Ratio on a wooden bench.

Theorem #3: Pythagorean Theorem

📍 Location: Palace of Amphitrite (Underwater Ruins, South of Thera, Paros & Anaphi)

• Sail south of Thera, Paros, and Anaphi to locate the Palace of Amphitrite.
• Dive into the ruins to find a lootable chest containing the Pythagorean Theorem.
• Beware of sharks while exploring the ruins!

Step 3: Return to Demokritos

After collecting all three theorems, return to Patrai and speak with Demokritos.

What Happens Next?

• He explains the significance of each theorem.
• He then shares his final theorem, which is not about mathematics—but about impressing a woman.
• This unlocks a new side quest: “Another Kind of Poetry.”

Rewards for Completing The Secrets of Greece

• XP
• 315 Drachmae
• Access to Another Kind of Poetry (a higher-level quest with better rewards)
