11 Bertotti Scamozzi's measurements are given in the local unit of measure, the Vicenza foot, and their accuracy is attested to, generally, by
Howard, Deborah and Longair, Malcolm, ‘Harmonic Proportion and Palladio's *Quattro libri*
’, Journal of the Society of Architectural Historians, 41 (1982), pp. 116–43 (p. 129)CrossRefGoogle Scholar; and by
Mitrović, , ‘Palladio's Theory of Classical Architecture’, pp. 120–21.Google Scholar It appears the case, too, that the size of Bertotti Scamozzi's foot corresponds closely (despite occasional claims to the contrary) to the usually specified size of the Vicenza foot (1ft = 35.7cm); see
Martini, Angelo, Manuale di metrologia (Turin, 1883), p.823.Google Scholar Dimensions for the orders are given infrequently in other surveys, so it is only possible to confirm Bertotti Scamozzi's reliability in a very few instances. Villa Cornaro at Piombino Dese, for example, is the subject of a recent and detailed survey: see
Palladio, Andrea: Villa Cornaro in Piombino Dese, ed. Mitrović, Branko and Wassell, Stephen R. (New York, 2006), in particular pp. 26–27,42 and 46.Google Scholar This gives the lower Ionic an average diameter of 69.68 cm and heights of 620.5 cm (front) and 638.0 cm (rear), to produce ratios of 1:8.90 and 1:9.16; and the upper Corinthian order an average diameter of 56.53 cm and heights of 593.0 cm (front) and 592.5 cm (rear), to produce ratios of 1:10.49 and 1:10.48. Bertotti Scamozzi gave the lower storey a diameter of 69.9cm (1.96ft) and a height of 632 cm (17.71 ft), producing a ratio of 1:9.04; and the upper storey a diameter at 57.5 cm and a height at 593 cm, producing a ratio of 1:10.17. Occasional dimensions for the orders are included on the survey drawings held at the Palladio Museum (and featured on their website; see above n. 3) and, although these are not necessarily more accurate, they further confirm Bertotti Scamozzi's reliability. The few measurements provided, which are for Palazzo Antonini in Udine (Ionic and Corinthian), Palazzo Porta Festa in Vicenza (Ionic), Villa Badoer at Fratta Polesine (Doric and Ionic), Villa Cornaro at Piombino Dese (Ionic) and Villa Thiene at Quinto (Doric), mostly correspond very closely with the figures specified by Bertotti Scamozzi.
