Johann Christoph Sturm (1635-1703) was a German mathematician and philosopher. He taught at the university at Altdorf founded in 1622 to serve the needs of nearby Nuremberg. He was the author of many books on mathematics and the natural sciences. *Mathesis Enucleata* (1695) (*The Elements of Mathematics*) was written as a textbook for his students. In 1700, it was translated into English with the title *The Elements of Mathematics, an Introduction to the Specious Analysis or Algebra.* The title page of the first 1695 edition is shown above.

*Mathesis Enucleata* was lavishly illustrated with forty-nine copper plate prints, some of which are shown in Figures 2 and 3. The reader can attempt to determine the particular mathematical situation and/or problem depicted.
