block capital

Broader term
capital

The simplest form of capital, in which the top is square and the bottom round. The transition between them is most simply achieved by a gradual change of profile, but there are other options. The surface may be decorated. Variations are block capital with chamfers where the angles have triangular chamfers to effect the transition and block capital with ridges where the square shape of the top of the capital is preserved down to the necking by means of ridges at the angles.
