Fauth, Philipp (1867-1941). 

Astronomische Beobachtungen und Resultate. – Kaiserslautern: Aug. Gotthold's Verlagsbuchhandlung, 1893-1895.

Fauth managed to alienate most of the selenographic community during his lifetime, with his intemperate criticism of other observers and his espousal of the theory that the moon was solidly covered with ice. But there is no denying that Fauth was a gifted observer, perhaps the last of the great selenographers to map the moon by hand and eye. Fauth was a schoolteacher for most of his life and maintained an observatory near Kaiserslautern. This is his first publication, containing 25 drawings of selected lunar features on 20 sheets, at a scale of 1:1 million.

The illustration shows the crater Aristarchus (feature A) in the Oceanus Procellarum (Ocean of Storms), and its companion crater Herodotus (H). The large W-shaped valley below Herodotus is the famous Schröter's Valley. Fauth was one of the most skilled of all selenographers at using the hachure shading technique, which indicates relief by short lines in the direction of maximum slope. Curiously, he abandoned this technique later in his career in favor of contour lines. Image source: Fauth, Philipp. Astronomische Beobachtungen und Resultate. Kaiserslautern: Aug.
