A compendium of spherical astronomy with its applications to the determination and reduction of positions of the fixed stars
Simon Newcomb's 1906 textbook on spherical astronomy, published by Macmillan in New York and London for university students and working astronomers computing star positions. The figures are line diagrams: circles and spheres carrying labelled radii, chords, dashed construction lines, arcs of latitude and longitude, and small arrows for direction of motion, usable as geometric ornament or schematic framing.
