Rivista di astronomia e scienze affini, 1910, a. 4, n. 02 (February)
An Italian astronomy journal issue from 1910, issued by the Società astronomica italiana with the Turin observatory, aimed at specialist readers of astronomy. Its pictures are plain line diagrams: geometric circles, triangles and labelled points for planetary geometry, and phase sequences of a shaded circle showing lunar or Venus phases, useful for designers wanting clean technical schematics.
