Athanasii Kircheri ... Musurgia universalis, sive ars magna consoni et dissoni, in X libros digesta : qua uniuersa sonorum doctrina, & philosophia, musicaeque tam theoricae, quam practicae scientia, summa varietate traditur...
A 1650 Latin treatise on music and acoustics by the Jesuit scholar Athanasius Kircher, printed in Rome by the heirs of Francesco Corbelletti for scholars and musicians. Its pictures are plain line diagrams in black on aged cream paper: geometric figures with lettered points, triangles, rhombi and pendulum-like sketches that a designer could borrow for schematic, technical, or scientific graphics.
