The Face of the Moon

Enlarged image

The Beer and Mädler map is crammed with detail that is almost impossible to appreciate with the naked eye; under magnification, an incredible richness is revealed. The illustration shows a mere corner of the northeast quadrant, with Aristotle at the left and the Alpine Valley at the right. Mädler inaugurated the practice of naming minor craters, such as Egede A,B, and C at bottom center, with Roman letters appended to the name of the nearest large crater. This portion of the map may be compared with the first engraving of the Alpine Valley by Bianchini (see item 11).
