“… mi sono proposto innanzi quelli ornamenti antichi delli cinque ordini i quali nelle Anticaglie di Roma si veggono: et questi tutti insieme considerandoli, et con diligenti misure esaminandoli ho trovato quelli che al giudicio comune appaiono più belli, et con più gratia si appresentano agli occhi nostri; questi anchora havere certa corrispondenza et proportione de numeri insieme meno intrigata, anzi ciascuno minimo membro misurare li maggiori in tante lor parti apunto. Laonde considerando più adentro quanto ogni nostro senso si compiaccia in questa proportione, et le cose spiacevoli essere fuori di quella, come ben provano li Musici nella lor scienza sensatamente, ho presa questa fatica più anni sono di ridurre sotto una breve regola facile, et spedita da potersene valere li cinque ordini di Architettura…”

Jacopo Barozzi da Vignola, Regola delli Cinque Ordini d’Architettura, Roma, 1562


“… I proposed to my self the ancient Ornaments of the five Orders which are seen among the Antiquities of Rome; and considering all together, and examining them by diligent Measures, I have found that those which seem most beautiful to common judgement, and which represent themselves with most grace before our Eyes, those I say have a certain correspondence and proportion of Numbers among themselves not intricate, seeing that each of the lesser Members measure the greater, punctually distributing them into so many parts. From whence considering more nearly, that all our Senses are pleased in this Proportion, and displeasing things are different from it, as the Musicians do most sensibly demonstrate in their Science; I have taken Pains these many years to reduce the said five Orders of Architecture under one brief Rule, easie, and which might readily be put in practice; and the manner which I have observed in it is thus”.

English translation by John Leeke from: The Regular Architect: or the General Rule of the Five Orders of Architecture of M. Giacomo Barozzio da Vignola, London, 1669


“Ces cinq ordres sont conformes aux mesures de Vignole, l’un des dix commentateur de Vitruve, & celui qu’on a suivi en France le plus généralement”.

Diderot & d’Alembert, L’Encyclopedie, article: “Architecture” by Jacques-François Blondel, Paris, 1751



The AutoCAD files in our library are not just a simple ‘scan-and-redraw’, they have been outlined following the method exposed by Jacopo Barozzi (1507-1573), generally known as Vignola, in his famous treatise: Regola delli Cinque Ordini d’Architettura (Rule of the Five Orders of Architecture). This book was originally published in Rome in 1562 and has become the very first best-and-long-seller in the history of architectural literature. As a matter of fact, after the first print, more than 500 other editions have been published throughout the centuries, in various countries and languages. Ever since, Vignola’s book has been the most widely recognized standard book, setting the canons of the Five Architectural Orders. Thus it has been the most used training book not only for architects, artists and craftsmen, but also for anyone wishing to gain first hand knowledge of Classical Architecture.

The files rendering the Five Orders of Architecture are available here and ready for use in the most widely employed CAD formats: DWG and Vectorworks.
