This question tests your recognition of the basic vocabulary of Greek interior ornament—the simple profiles that shape many moldings. In Greek decorative language, the core profiles you’re most likely to see are the fillet, a narrow flat edge; the bead, a small rounded ridge; the cavetto, a concave quarter-round curve; and the scotia, a shallow concave groove. These four give you the essential toolkit for creating transitions and subtle shadows between surfaces like friezes, cornices, and capitals. They are repeatedly used across Greek ornament because of their straightforward forms and strong readability in light and shadow. While other profiles exist—such as a torus, which is a larger rounded molding—these four are usually taught as the standard set for Greek moldings. Recognizing them helps you identify classical interiors more quickly and accurately, since they represent the foundational shapes that define Greek ornamental vocabulary.
