Dynamic symmetry; the Greek vase
Jay Hambidge's 1920 Yale University Press study Dynamic Symmetry; The Greek Vase, published in New Haven and New York, analyses the proportions of ancient Greek vessels for designers and students of design. The pictures are line drawings of vase profiles overlaid with dotted construction lines, rectangles and diagonals that show how each shape was laid out geometrically, a method a designer could borrow for sizing forms against a root rectangle.
