Regola delli cinqve ordini d'architettvra,
Regola delli cinqve ordini d'architettvra is an architectural treatise on the five classical orders, printed in Siena in 1635 by Bernardino Oppi, drawing on the work of Vignola and Michelangelo and dedicated to patrons and students of building design. The plates show arched bays, columns, entablatures and pedestals drawn in fine engraved line with Italian captions and module measurements, giving a designer clear, reusable proportions for classical arcades, doorways and capitals.
