“At present, books considered ‘pop-up’ or movable are popular sources of delight for children and adults alike. However, the types of books today’s audiences associate with such a genre are the result of a somewhat long development and, consequently, form an intriguing niche in the ‘history of the book.’ The first movable books actually predate the print culture. The earliest known examples of such interactive mechanisms are by Ramon Llull (c.1235-1316) of Majorca, a Catalan mystic and poet.” (Thanks Coudal Partners!)
