Thuluth instance of script
Thuluth (Arabic: ثُلُث, Ṯuluṯ or Arabic: خَطُّ الثُّلُثِ, Ḵaṭṭ-uṯ-Ṯuluṯ; Persian: ثلث, Sols; Turkish: Sülüs, from thuluth "one-third") is a script variety of Islamic calligraphy. The straight angular forms of Kufic were replaced in the new script by curved and oblique lines. In Thuluth, one-third of each letter slopes, from which the name (meaning "a third" in Arabic) comes. An alternative theory to the meaning is that the smallest width of the letter is one third of the widest part. It is an elegant, cursive script, used in medieval times on mosque decorations. Various calligraphic styles evolved from Thuluth through slight changes of form.History
The greatest contributions to the evolution of the Thuluth script occurred in the Ottoman Empire in three successive steps that Ottoman art historians call "calligraphical revolutions":The first revolution occurred in the 15th century and was initiated by the master calligrapher Sheikh Hamdullah.
The second revolution resulted from the work of the Ottoman calligrapher Hâfız Osman in the 17th century.
Finally, in the late 19th century, Mehmed Şevkî Efendi gave the script the distinctive shape it has today.
