Unbuilt works Like many other architects, Vignola submitted his plans for completing the facade of San Petronio, Bologna. Designs by Vignola, in company with Baldassare Peruzzi, Giulio Romano, Andrea Palladio and others furnished material for an exhibition in 2001 Written works His two published books helped formulate the canon of classical architectural style. The earliest, Regola delli cinque ordini d'architettura ["Canon of the five orders of architecture"] (first published in 1562, probably in Rome), presented Vignola's practical system for constructing columns in the five classical orders (Tuscan, Doric, Ionic, Corinthian and Composite) utilising proportions which Vignola derived from his own measurements of classical Roman monuments. The clarity and ease of use of Vignola's treatise caused it to become in succeeding centuries the most published book in architectural history. Vignola's second treatise, Due regole della prospettiva pratica ["Two rules of practical perspective"], published posthumously with extensive commentary by the mathematician Ignazio Danti (Bologna 1583), favours one-point perspective rather than two-point methods such as the bifocal construction. Vignola presented— without theoretical obscurities— practical applications which could be understood by a prospective patron. Notes References Attribution Sources (Remains a standard monograph.)
