Regola delli cinqve ordini d'architettvra
Vignola's Regola delli cinque ordini d'architettura, the engraved treatise on the five classical orders issued in Rome in 1563 for architects, masons and students who needed measurable models. The plates give columns, bases, capitals, entablatures, pedestals and arched doorways drawn in elevation with dimension lines and module numbers; many leaves here are versos showing faint ghost impressions, useful as pale architectural underlays as well as precise line diagrams.
