English translation: 

Years ago in the time of Romanticism, painted Petrus van Schendel the painting you see here before you. The painting is about Antonius. A hermit who dedicated his whole life to God. But the dark figure in the background slowly creeped in, bearing only bad intentions.

Antonius did everything in his power to discover the true identity of the figure. He finally discovered the right book, only to discover that the last page had been torn out. The dark figure had sabotaged Antonius by tearing the page out of the book, ripping it to pieces, and hiding them. After all these years, you have been given the task to find the missing piece and to solve the Mystery of Antonius.
