Shah Mahmud al-Nishapuri, known as 'Zarin Qalam' (Golden Pen), lived and worked in Tabriz for most of his life. He was a royal calligrapher to Shah Tahmasp (d.1574) and was without doubt one of the greatest calligraphers of his time, renowned for his "perfect nasta'liq". When the Shah lost interest in the Arts, Shah Mahmud moved to Mashhad and worked there under the patronage of Ibrahim Mirza (d.1577) until he died (Norah M.
