Codex Seraphinianus

The Codex Seraphinianus was published in 1981 by the Italian artist Luigi Serafini. It resembles a manuscript, and depicts bizarre illustrations of flora, fauna, and foods.

Serafini used a writing system using a constructed language, which could not be decoded by linguists, until Serafini stated in 2009 that there was no meaning behind it. Instead, it was supposed to evoke the sensation children feel looking at books they cannot yet understand.
