If priority of use be held as establishing a standard in decoration, wood-panelling should be regarded as a sham and plaster-panelling as its lawful prototype; for the use of stucco in the panelling of walls and ceilings is highly characteristic of Roman interior decoration, and wood-panelling as at present used is certainly of later origin. But nothing can be more idle than such comparisons, nor more misleading than the idea that stucco is a sham because it seeks to imitate wood. It does not seek to imitate wood. It is a recognized substance, of incalculable value for decorative effect, and no more owes its place in decoration to a fancied resemblance to some other material than the nave of a cathedral owes its place in architecture to the fancied resemblance to a ship.
In the hands of a great race of artistic _virtuosi_ like the Italians, stucco has produced effects of beauty which in any other substance would have lost something of their freshness, their plastic spontaneity. From the delicate traceries of the Roman baths and the loveliness of Agostino da Duccio's chapel-front at Perugia, to the improvised bravura treatment of the Farnese theatre at Parma, it has served, through every phase of Italian art, to embody the most refined and studied, as well as the most audacious and ephemeral, of decorative conceptions.
It must not be supposed that because painting, panelling and tapestry are the noblest forms of wall-decoration, they are necessarily the most unattainable. Good tapestry is, of course, very expensive, and even that which is only mediocre is beyond the reach of the average purchaser; while stuff hangings and wall-papers, its modern successors, have less to recommend them than other forms of wall-decoration. With painting and panelling the case is different. When painted walls were in fashion, there existed, below the great creative artists, schools of decorative designers skilled in the art of fresco-decoration, from the simplest kind to the most ornate. The demand for such decoration would now call forth the same order of talent, and many artists who are wasting their energies on the production of indifferent landscapes and unsuccessful portraits might, in the quite different field of decorative painting, find the true expression of their talent.
