3Their bases are to be half a diameter in height. The plinths, which are to be circular, are half the height of the base, with a torus and fillet on them as high as the plinth. The height of the capital is to be half a diameter. The width of the abacus is equal to the lower diameter of the column. The height of the capital must be divided into three parts, of which one is assigned to the plinth or abacus, another to the echinus, the third to the hypotrachelium, with its apophyge.
3The height of their bases should be one half of that thickness. The plinth of their bases should be circular, and in height one half the height of the bases, the torus above it and congé being of the same height as the plinth. The height of the capital is one half the thickness of a column. The abacus has a width equivalent to the thickness of the bottom of a column. Let the height of the capital be divided into three parts, and give one to the plinth (that is, the abacus), the second to the echinus, and the third to the necking with its congé.
