without good reasons. The draughtsman, by strictly observing these proportions, is secured from criticism, is sure of doing well, and of obtaining the approbation of judges.
The following are the proportions thus settled :
In all the orders, the entablature is one quarter as high as the column, and tht pedestal a third.
Each of these three parts is subdivided into three others, viz.
The Pedestal into the Cornice, Dye and Base.
The Column into the Base, Shaft, and Capital.
The Entablature into the Architrave, Frieze, and Cornice.
Care must be taken to proportion the size of the col- umn to its order, its own height, and the height of the edifice it is to ornament.
The height of the Tuscan Column, including its base and capital, is seven times its diameter ; of the Dorick, eight times ; of the Ionick, nine times ; and of the Co- rinthian, ten times.
The subdivisions are also regulated by this scale. A radius, or half diameter of a column, is called a Mod- ule, which, when once ascertained,determines the height of the frieze, cornice, shaft, &c. These modules are each divided into twelve equal parts in the Tuscan and Dorick orders, and into eighteen in the Ionick and Co- rinthian.
The number of Modules, or half diameters, which the subdivisions of each order measure, is as follows.
