The 'Codex Seraphinianus' is a beautifully illustrated encyclopedia that should make absolutely no sense to you. The original book was created by Luigi Serafini in the 1970s, with the intention of creating something "meant to convey to readers how children feel when they read books they cannot understand."
The encyclopedia seems to come from an Alice in Wonderland-type world, complete with fantastical drawings of plants, creatures and contraptions. The accompanying text has been studied by linguists who have deemed that the script is a hybrid of Eastern and Western writing, but it cannot be decoded and there is no real meaning behind it.
The newest edition of the surreal 250-page hardcover Codex Seraphinianus has been redesigned by Serafini to includes even more strange and beautiful imagery and text that is not meant to be understood.
