Behind the scenes
- As the text of the film prop in which this duodecimo is mentioned is derived from the book Alchemists Through the Ages, the work in question is presumably "The Elixir of the Philosophers, or the Transmutatory Art of Metals", a treatise attributed to Pope John XXII.
- The city of Lyon is only mentioned in the book on alchemy in which Harry Potter, Ronald Weasley and Hermione Granger learn about the Philosopher's Stone in the film adaptation of Harry Potter and the Philosopher's Stone. The excerpt mentioning Lyon can only be seen in the American edition, as in the British edition the sentence is cut off the top of the screen.
