Scrollwork in its strict meaning is rather different; the scroll is imagined as the curling end of a strip or sheet of some flat and wide material. It develops from strapwork, as the ends of otherwise flat elements, loosely imitating leather, metal sheets, or broad leaves rather than plant tendrils. Rather than the "profile" view displaying the spiral, the forms are often shown front on with the width of the strip seen. It begins in the Renaissance, and becomes increasingly popular in Mannerist and Baroque ornament.
