Scroll-forms containing animals or human figures are said to be "inhabited"; more often than not the figures are wildly out of scale with the plant forms. Frequently, especially in spreading designs, an upright element imitating the main stem or flower-stalk of the plant appears as a central element protruding vertically from the base, again as in the Ara Pacis panel. This may be termed a "standard" but is not a necessary element; it gives the design a top and bottom, which may be appropriate for architecture or furniture, but many designs on textiles and pottery are intended to have no main orientation for the viewer. The standard was frequently depicted as a fanciful candelabra in grotesque designs, in which it is an important element, central to the composition.
