| 5min = They receive a letter for Guy de Chaulliac, he is critically ill and begs them to leave. The messenger is coughing and stumbles. The librarian informs them that he found a letter from Pope XXII to Gasbert de Valle congratulating him for the construction of the palace of the Popes.

| 10min = Alchemy books disappeared : Liber de compositione alchimiae, De investigatione perfectionis (Geber), De mineralibus (Albart Magnus), Opus maius (Roger Bacon), The book of Abraham the Jew, Ars Magna by Ramon LLul. It is disturbing because Ramon LLul is very controvertial, in between alchemy and witchcraft.

| 15min = Alchemy : Some books disappeared : L’élixir des philosophes and L'art transmutatoire. Nobody knew those books were here ! Except the pope himself and the librarian. Also, the rumours says that it was John XXII who wrote "L’élixir des philosophes" and "L'art transmutatoire". The librarian explains that for some reason, the pope seemed passionate about alchemy, and at some point in his life he made a bull to ban alchemy ! Very strange.
