Used in chancelleries' orders in the past. It was labeled the Diwani script because it was used in the Ottoman diwan and was one of the secrets of the sultan's palace. The rules of this script were not known to everyone, but confined to its masters and a few bright students. A very popular style for ornamental works largely developed in the Turkish courts. It uses no vowel makes and its letters are dotted and unconventionally joined together. It is defined by its beautiful curved letters, merged to form complex shapes and decorative forms. This complexity makes it harder to use with long text, so a simpler version of the script is needed if a calligrapher is to use it for that purpose.
