The Chilean director, cartoonist, composer, and visual artist Alejandro Jodorowsky (*1929) dedicated a voluminous notebook to the script for his film Dune, after the 1965 science-fiction novel of the same name by Frank Herbert. He even printed the title on this book. But his ambitious project remained unrealized, and in the end, the 1974 notebook instead brings together his intensive research about the historical Tarot de Marseille. For three years, Jodorowsky followed the paths of the famous tarot deck to explore its origins and its historical development, as well as the various teachings and interpretations embedded within it. The notebook contains the result of his encounters, conversations, and studies in the form of texts, collages, and diagrams, which are reproduced here in a selection.With an introduction by Chus Martínez, Agent, Member of Core Group, and Head of Department for dOCUMENTA (13).
