"Genuina Corporis Lunaris Facies, prout in Oppositione Vernali...", Zahn, Johannes

This marvelous engraving is an early view of the moon graphically depicting its craters based on observations made during the summer of 1694. Although Eimmart presents a much more detailed view of the moon than his predecessors, it is still filled with many inaccuracies. Some features are misplaced, the outlines of most of the maria are in error, and some prominent craters are not depicted at all. Surrounding the moon are diagrams of the various phases of the moon as well as a lunar eclipse. This engraving appeared in the very rare Specula Physico-Mathematico-Historica Notabilium…, an encyclopedia of science published by Johannes Zahn. Created by Georg Christoph Eimmart, an engraver and instrument maker who was also one of Germany's foremost mathematicians and astronomers.
