Elementargesetze der bildenden Kunst, Grundlagen einer praktischen Asthetik
A German aesthetics treatise by Hans Cornelius, published in Leipzig and Berlin by B.G. Teubner in 1908, meant for students and practitioners of the visual arts. Its plates are black-and-white photographs and drawings of decorative objects: a rotated ceiling fresco, a plain shallow dish with a band of wave ornament, a coffered ceiling rosette, and a drawn table, chair and mirror. A designer could take from them the logic of radial and concentric ornament, the rhythm of repeated borders, and the proportions of turned furniture legs.
