This loop-handled 'krater' vase form, with ribbon-tied 'Eternity' bats displayed beneath lapped flanges springing from arched cartouches bearing festive satyr-masks, derives from an Egyptian porphyry antiquity belonging to the Marquis del Carpio, Viceroy of Naples, and engraved in Johann Bernard Fischer von Erlach's Entwurff einer historischen Architektur, Vienna 1721 (Volume V. Fig.1). It was reissued in Leipzig, 1725, and an English version was published by T. Lediard entitled Plan of Civil and Historical Architecture, 1730. The fashion for antiquity in the later 18th century encouraged the copying of such vases in a wide variety of materials. Amongst the most celebrated manufacturers of such exotic ivory vases at this period was the Turin carver G.M. Bonzanigo (d.1820). See C. Bertoletto Giuseppe Maria Bonzanigo, Turin 1989, plate XVI.
