The power of the
sultan, or of the regional rulers, was often proclaimed quite openly and obviously in visual form. Architecture was most useful towards this end; a grandiose building, dominating the neighbourhood or (even better) the city skyline, makes a bold statement of power. On a smaller scale, the power of the ruler could be announced explicitly in written form, such as by including his name or title in the decoration of a building or even a manuscript. The imperial
tughra is perhaps the most memorable example of this aspect of the visual language of power.
