What was the meaning of the extraordinary collection of texts, sketches and graphic prints that Edvard Munch called The Tree of Knowledge of Good and Evil? Get a glimpse into the artist's world of ideas through one of the greatest mysteries he left behind. In this book you can experience The Tree of Knowledge as it was found in Munch's home, with both loose, bound and blank pages. An essay by art historian Nora Ceciliedatter Nerdrum provides new perspectives on Munch's most enigmatic project. No one knows why he created this album. Was it a book proposal? Or was it an attempt to organise his ideas?What we do know is that he worked on the album for several decades, and that it was probably never completed. The most astonishing part of its content is perhaps Munch’s own texts about love, jealousy, life and death, composed in large, colourful lettering.
