Section + Elevation Detail of Ornamental frieze on Arches
there are little holes on the section profile, possible made by artisans, carving the pieces.
the drawing illustrates the form of the frieze to be placed along arches. Its appearance is rendered though the addition of light and shadow details. Its 3dimensional form can be understood through the section in the upper part of the drawing.
