The eponymous leitmotif of the Rococo era is rocaille, flourishing, asymmetrical shell ornamentation in C and S scrolls, characterised by great lightness and elegant delicateness. Franz Anton Bustelli created his Stoup using the flowing, undulating forms of rocaille tendrils and volutes. As the body of the structure blends as it were with the reliefwork of the ornament, no lathe is required to make this basin for holy water, only a modeller and an embosser, who forms the numerous flowers and leaves freehand and subsequently decorates them.
