Italienische Studien : zur Geschichte der Renaissance
A German art-historical study of Italian Renaissance art by Hermann Hettner, published in Braunschweig by Vieweg in 1879 for scholars and readers of art history. The pictures are plain line diagrams of musical intervals with Greek and Roman tuning notation, and one line drawing of a seated bearded figure beside a lion on a pedestal, so a designer could take clean, schematic diagram layouts and a classical sculptural study.
