architecture
Quick Summary
In architecture, a torus is a large molding with a convex profile. It is commonly found as the lowest molding in the base of a column. Moldings, in general, are defining elements that contour edges and surfaces, originating from structural functions in prehistoric building and later evolving into decorative elements in monumental architecture. The torus molding, specifically, has a profile that approximates a semicircle or semiellipse and is one of several standardized shapes in architectural design.12
