Hans Blum's manual on the five classical orders, printed by Christoph Froschauer in Zurich in 1550 for masons, carpenters and builders north of the Alps. Woodcuts show columns drawn in elevation with capitals, entablatures, bases and coffered soffits, overlaid with numbered measuring scales, dotted construction lines and inscribed circles that a designer can lift as diagram, ornament or grid.
