“The Codex Seraphinianus was written and illustrated by Italian graphic designer and architect, Luigi Serafini during the late 1970’s. The Codex is a lavishly produced book that purports to be an encyclopedia for an imaginary world in a parallel universe, with copious comments in an incomprehensible language. It is written in a florid script, entirely invented and completely illegible, and illustrated with watercolor paintings.”
