Saggi di astronomia popolare, 1917
Saggi di astronomia popolare is a 1917 Italian popular astronomy text compiled by Società Urania with the Osservatorio astronomico di Torino and Giovanni Boccardi, written for general readers. Its pictures are plain technical tables and geometric diagrams: a star catalogue table listing names, positions, magnitudes and periods in tidy columns, and a line drawing of arcs, chords and labelled points on an open page, useful for designers wanting clean scientific layout references.
