CHAPTER XVI — Critical Commentary & Notes

On the Composition and Mouldings of the Cornice (Cornicione).

Historical & Mathematical Commentary

• Vitruvius’s Rule of Equal Height and Projection (*Ecphora*, Vitruvius III.5.11): Pacioli repeatedly emphasizes Vitruvius’s fundamental rule of classical profile geometry: uti proiecturae earundem sint quantae altitudines (“that the projections [sportafore] of the mouldings be equal to their heights”), which places the outer profile of the cornice along a \(45^{\circ}\) diagonal line!

Constantin Winterberg’s Commentary (1889 Edition)

• Winterberg Footnotes 1–2 (Arch. Cap. XVI, p. 328): (1) The repeated words ‘e dali antichi’ in the 1509 print are a dittography to be deleted for sense. (2) Bead-and-reel (Paternostri) or olive-leaf moulding. (Winterberg Fussnoten 1–2 (Arch. Cap. XVI, S. 328): 1) Die Worte des Textes: „e dali antichi“ des Sinnes wegen zu streichen. 2) Paternostri oder Olivenschmuck.)
