I dieci libri dell'architettvra
Vitruvius Pollio's architectural treatise I dieci libri dell'architettura, printed in Venice in 1584 by Francesco de'Franceschi, edited by Daniele Barbaro, and aimed at architects and scholars of classical building. The four pictures are engraved plans and a sundial diagram, with ground plans of a temple, a forum-like complex, and a circular sundial with numbered hour lines. A designer could take from them the clean, schematic plan-drawing style, with thick outlines, dotted colonnades and tidy lettering keys, as a model for diagrammatic layouts.
