Saggi di astronomia popolare, 1912
Saggi di astronomia popolare is a 1912 Italian collection of popular astronomy essays, associated with the Società Urania and the Turin astronomical observatory, with Giovanni Boccardi among its contributors, aimed at general readers. Its plates are plain photographic and diagrammatic illustrations: a long-exposure comet photograph against a dark sky, a large refractor telescope inside a domed observatory, and simple geometric line drawings of a circle and a sighting diagram, useful to designers wanting clean scientific imagery with strong diagonals and dark-field contrast.
