A good friend of mine once showed me some images online of Codex Seraphinianus, the visual encyclopedia of an unknown world created by Italian artist Luigi Serafini. Approximately 360 pages, Serafini created the codex during 30 months between 1976 and 1978. The book is filled with beautiful pages of fantastic creatures in an unknown language, and for the first time since it was published it has been released in an affordable format: free. You can find it on the issuu self publishing site where you can view it and download it, for free. Paper, out of print editions of this book usually range upwards of $400, so this is truly a gem. I am really very excited about this.
