Saggi di astronomia popolare, 1911, a. 1, f. 01
An Italian popular astronomy booklet from 1911, produced by Giovanni Boccardi with the Turin Astronomical Observatory and the Societa Urania for a general readership. The pictures pair a halftone photograph of a seated-then-standing marble statue of a scholar holding a globe with a line diagram of intersecting elliptical orbits labelled with letters and Greek symbols. A designer might take from them the contrast between the monumental portrait sculpture and the spare, annotated geometry of orbital charts.
