After the dawn of Islam, and throughout the subsequent centuries, Arabic calligraphy developed into numerous schools that varied in type. Among the most important and widespread are the kufic, naskhi and thuluth scripts. While kufic was the earliest of the three, suitable for calligraphic works, it was not appropriate for utilitarian tasks. This led to the development of the naskhi script, which was widely used in the practical fields of daily civic life.
