 The cult of the individual artistic genius, which was an important part of the Renaissance theoretical basis for the distinction between "fine" and other art, drew on classical precedent, especially as recorded by Pliny the Elder.Some other types of object, in particular Ancient Greek pottery, are often signed by their makers, or the owner of the workshop, probably partly to advertise their products.The decline of the concept of "fine art" is dated by George Kubler and others to around 1880, when it "fell out of fashion" as, by about 1900, folk art was also coming to be regarded as significant.
