Assassin’s Creed Mirage book puzzle
Once you arrive in the library during The Serpent’s Nest mission, you’ll already have collected four books of different colors: black, white, yellow, and blue. A poem you can read in the room seems to allude to four items that correspond to these books: the ocean, the desert, a cobra, and a dove.
Up the stairs, you can place these four books on altars, and doing so in the right order will solve the puzzle and reveal a secret room for you to advance through.
