- The mission "A Towerful of Mice" tells a story of a cruel noble family, that hid in a tower when the peasants rebelled and were eaten by mice. All these details are similar to the polish tale of Prince Popiel. A very similar tale is frequently told in Germany, surrounding a Guardtower in the city of Bingen  (An extra bit of trivia: Stara Baśń, a movie that includes this story, was made with Michał Żebrowski as a main character. Michał Żebrowski played Geralt in the TV series 'The Hexer').
- The book "Golem, or Man's Most Faithful Servant" holds a tale of a dwarf who crafted a golem to defend the dwarves from prosecution, which is very similar to the tale of the golem of Prague, about Judah Loew ben Bezalel 'המהר"ל' who made a golem to defend the Jewish community from pogroms.

- The pact of von Everec with the Mirror Man resembles a Polish folk tale about Twardowski, a noble who sold his soul to the devil for magical powers. The pact states that the devil is forced to fulfill three wishes (like Mirror Man), and Twardowski is supposed to come to Rome. The devil lures Twardowski to the inn called "Rome" to take his soul, but Twardowski in his last moment says a prayer, and is saved, but must stay on the Moon till the end of the world as his penance.

Appropriately, the Necronomicon, which was referenced in works of H.P. Lovecraft, can be found as an in-game book. In "Blood and wine", in the hut of the witch of the lynx crag, a book named "Liber ivonis" can be found, a reference to an occult book mentioned in Lovecraft's stories. Geralt makes a comment about that book being banished by the sorcerers.
- In Velen, not too far from the villaige of Heatherton, there is a Cyclops guarding a treasure, but is also to be found a herd of sheep. This is a direct reference to The Odessy, by Homer, in which Odysseus and his men are beset by the Cyclops, Polyphemus
- In Oxenfurt, near the northeastern gate, you can find a man who has a wyvern in a cage. He tries to cheat you, as well as the soldiers that are there, by telling that the beast inside the cage is a basilisk, but Geralt notices the fraud. After this, the wyvern breaks the cage and kills that guy. This quest, called 'The Most Truest of Basilisk', represents a scene from Time of Contempt, the 4th book of Geralt's saga by Andrzej Sapkowski. In the book Ciri is hanging around Gors Velen with another kid when she suddenly enters a tent and sees a man with a wyvern in a cage. The same thing happens here. The man says that it's a basilisk, trying to trick everyone there, but Ciri says that it is a wyvern... Eventually, the wyvern breaks the cage and kills the guy.

- In the quest "The Great Escape", Geralt and Yennefer go to meet a man who escaped from the prison. His name is Abbé Faria, which is a reference to the priest that Edmond Dantes meets in the book The Count of Monte Cristo.

- There is a trophy called "Fist of the South Star", a reference to the manga "Fist of the North Star".

- On one of the notice boards there's a notice from "Ismael" claiming "if you see a white whale in the sea, let it swim on. It's mine. If anyone catches it before me, Freya be my witness, I will stab that wretch to death with my harpoon" Clearly a reference to Ishmael and Moby Dick / the whale by Herman Melville.
- There is an in game book titled "How to Avoid Colossal Vessels" which is a reference to "How to Avoid Huge Ships"

A reference to Shakespeare's Hamlet and the famous "Alas, poor Yorick" scene, and Hamlet as a character.
- The mission "The Play's the Thing" is a reference to Shakespeare's play Hamlet, where Hamlet says "The play's the thing wherein I'll catch the conscience of the King."
- On a notice board in Toussaint, the poet and tournament-announcer Le Papillon accuses a guy named William of Stratford to "steal rhymes". That is an obvious reference to the old debate, whether William Shakespeare, born in Stratford-upon-Avon, was indeed the author of his plays and poems.
- The name of the side quest Waiting for Goe and Doh is an obvious allusion to Samuel Beckett's play "Waiting for Godot".
- Captain Wolverstone and his ship Atropos are right from Sabatini's book 'Captain Blood'
