(1565 - 1635) was the most renowned Persian miniaturist, painter and calligrapher of the Isfahan School, which flourished during the Safavid period under the patronage of Shah Abbas I. He is considered to be one of the foremost Persian artists of all time. He received his training in the atelier of his father, Ali Asghar, and was received into the workshop of Shah Abbas I at a young age. At the age of about 38 he received the honorific title of Abbasi from his patron, but soon left the Shah's employ, apparently seeking greater freedom to associate with simple people. In 1610 he returned to the court and continued in the employ of the Shah until his death. His specialty was the Persian miniature, with a preference for naturalistic subjects often portrayed in an effeminate and impressionistic manner,a style which came to be popular during the late Safavid court.
