This imposing acanthus-carved mirror with its original decorative scheme is derived from designs by Giovanni Paolo Schor, dated circa 1660-1670, now in the Museum der Bildenden Kunste, Leipzig, (illustrated in E. Colle, Il Mobile Barocco in Italia, Milan, 2000, no. 24, p. 110); as well as other designs further developed several decades later by the Roman ornamentalist Filippo Passarini (1638-1698), in his pattern book of 1698, described as 'Nuove inventioni d'ornamenti d'architettura e d'intagli diversi utili ad argentieri intagliatori ricamatori ed altri professori delle buone arti del disegno.... One of his progetto per specchiera e acquasantiera's, illustrated in F. Sabatelli, La Cornice Italiana, Milan, 1992, p. 69, ill. 83. This type of carving was not only produced in Rome but also in other regions of central Italy, including Emilia and further north. Acanthus scrolls, often embellished with floral sprays, fruits or figures, here remain untouched and very pure. A related two-tone giltwood mirror was sold Christie's, London, 23 June 1999, lot 99.
