A 1497 Latin compendium printed in Milan by Simon Bivilaqua, gathering Cleonides' harmonic treatise, Vitruvius' ten books on architecture and Frontinus on aqueducts, for scholars and humanist readers. Its pages show a geometric diagram of a pentagon-like figure with ruled grids, an ornate woodcut-initialed Latin title block, and circular harmonic wheels with divided segments and labelled lines, offering a designer rich sources for classical geometry, decorative initials and diagrammatic layouts.
