Ptolemy Illustrations

We have adopted the early Greek scientist Ptolemy as our mascot for those who are just getting started.  Ptolemy led the way.

Each tutorial  booklet has a Ptolemy illustration on the cover.  You are free to use and adapt this artwork for your own booklet translations, promotions, and other projects.  This page gives you access to finished cover illustrations as well as some preliminary concept sketches that have not been used in any booklets.
