Saggi di astronomia popolare, 1915
Saggi di astronomia popolare is a 1915 Italian popular-astronomy compilation produced by the Società Urania and the Turin astronomical observatory, with Giovanni Boccardi among its contributors, aimed at general readers. Its pictures are plain technical diagrams and photographs: a geometric figure with labelled axes, a circular orbit sketch, paired dark-frame views of a solar disc, and a pair of lunar hemisphere photographs with a printed caption, offering a designer clean scientific line work and high-contrast monochrome imagery.
