Dynamic symmetry; the Greek vase
Dynamic Symmetry; the Greek Vase is a 1920 Yale University Press study by Jay Hambidge, published in New Haven and New York, that analyses the proportions of Greek vase shapes using geometric construction for designers and art students. The four plates show outline drawings of amphora and jar profiles overlaid with dotted construction lines, diagonals and rectangles that reveal how each vessel's silhouette was built from root-rectangle proportions, a method a designer could adapt to lay out balanced forms.
