nastaʿlīq script, predominant style of Persian calligraphy during the 15th and 16th centuries. The inventor was Mīr ʿAlī of Tabrīz, the most famous calligrapher of the Timurid period (1402–1502).
A cursive script, nastaʿlīq was a combination of the naskhī and taʿlīq styles, featuring elongated horizontal strokes and exaggerated rounded forms. The diacritical marks were casually placed, and the lines were flowing rather than straight. Nastaʿlīq was frequently incorporated into the paintings of the early Ṣafavid period (16th century) and is traditionally considered to be the most elegant of the Persian scripts.
