After the introduction of Islam in the 7th century, Persians adapted the Arabic alphabet to Persian and developed the contemporary Persian alphabet. The Arabic alphabet has 28 characters. An additional four letters were added by Iranians , which resulted in the 32 letters currently present in the Persian alphabet.
Around one thousand years ago, Ibn Muqlah (Persian: ? ? ) and his brother created six genres of Iranian calligraphy, namely "Mohaqiq", "Reyhan", "Sols", "Naskh", "Toqi" and "Reqa". These genres were common for four centuries in Persia. In the 7th century (Hijri calendar), Hassan Farsi Kateb combined the "Naskh" and "Reqah" styles and invented a new genre of Persian calligraphy named "Ta'liq". In the 14th century, Mir Ali Tabrizi combined two major scripts of his time, i.e. Naskh and Taliq, and created a new Persian calligraphic style called "Nas'taliq". In the past 500 years Nasta?l?q (also anglicized as Nastaleeq; Persian: ? nasta?l?q) has been the predominant style for writing the Perso-Arabic script.
In the 17th century Morteza Gholi Khan Shamlou and Mohammad Shafi Heravi created a new genre called cursive Nasta?l?q Shekasteh Nasta?l?q (Persian: ?)). Almost a century later, Abdol-Majid Taleqani, who was a prominent artist at the time, brought this genre to its highest level. This calligraphic style is based on the same rules as Nas'taliq. However, cursive Nas'taliq has a few significant differences: it provides more flexible movements, and it is slightly more stretched and curved. Yadollah Kaboli is one of the most prominent contemporary calligraphers within this style.
