ornament on the surface of the molding.
The heights of the parts of the capital are to be so regulated that three of the nine parts and a half, into which it was divided, lie below the level of the astragal on the top of the shaft. The remaining parts are for the cymatium, abacus, and channel. The projection of the cymatium beyond the abacus is not to be greater than the size of the diameter of the eye f the volute
In the case of a concave-convex profile, a distinction is made between cyma recta and cyma reversa, with the cyma reversa, the inverted and therefore hanging cyma, being the usual form.
Originally, the individual types of cymatia were linked to the corresponding individual building codes and the associated ornament systems and in this way could be clearly distinguished from one another. In the Hellenistic and Roman periods, however, the types mixed, at the same time further refinement and embellishment with numerous details (acanthus, palmettes, medallions) took place.
