Decorative Arts
Decorative arts in the life of the Turks go back to the first century B.C.
The most striking examples of decorative art were produced during the Seljuk and Ottoman periods in enamelled tile making, miniatures, filigrees, marbling, coloured glass making, calligraphy, gilding, engraving and glass and repousse work. Being entirely applied arts, these forms were regarded as crafts rather than art. Though styles were many and varied, artists never signed their work.
