When illustrating Palladio, the British architect Isaac Ware ("The Four Books of Andrea Palladio's Architecture", London 1738; "illustration, right") laid out the Doric order as an exercise in modular construction. The module he selected was a full column diameter taken at the base. He set his columns, 15 modules tall, at an intercolumniation of 5½ modules. His architrave and frieze, without the cornice, is equal to one module.
