Art has always has a special place in Persia. One of the most important arts in Iran is calligraphy, which features many different styles. The Persian alphabet has 32 letters written from right to left. One of the most beautiful Persian calligraphic styles is Nastaliq which is considered to be a symbol of Persian art around the world. Nastaliq style was founded by “Mir Ali Tabrizi” in 8th century. Ancient treatises record that “Mir Ali” had a dream about wild geese and their fluid movements. It was the soft movements of those birds during flight that inspired Nastaliq. After Mir Ali Tabrizi, there were many calligraphers such as his son; Mirza Abdullah, Sultan Ali Mashhadi and Mir Ali Heravy who contributed to the refinement of Nastaliq style. Another master in Persian calligraphy, Mir Emad Hasany developed the style further. Developments made by Mir Emad are still inspiring modern Persian calligraphers 400 years later. Mir Emad trained many disciples and spread the Nastaliq style among Islamic countries in central Asia. In the 13th and 14th century prominent masters in Persian Calligraphy, such as Asadullh Shirazi, Mirza Gholamreza Esfahani, Mir Hossein, and Mohammadreza Kalhor continued to refine the Nastaliq style. Nastaliq style has many principles and rules. The most important of them are the combination, location, coordination, weakness, strength, surface, rotation, virtual ascent and decent. Calligraphy is different from simple writing of letters and typography. Calligraphy is a spiritual are, which is found in almost all cultures. In the East, and particularly in Islamic countries and Iran, it has great importance among the visual arts. It has always been at the forefront of artistic developments and has evolved over time. Nastaliq style is the most complete and most popular Persian Calligraphic style. Regularity, moderation, and sobriety are its most important features and because of this it has been called the Bride of Islamic Writing. Nowadays, more than 700 masters and teachers of Persian Calligraphy in Iran are active and are training students in this field. The Iranian Calligraphers Association (ICA), founded in 1950, is the oldest and the most prominent art association in Iran. The ICA is unique in the Middle East in terms of antiquity and impact.
