Sultan Muhammad Nur (d. circa AH 940/1533-34 AD) was a pupil of Sultan 'Ali Mashhadi and a scribe at the court of Mir 'Ali Shir Nawa'i, minister to the Timurid ruler Sultan Husayn Mirza Bayqara. His recorded works are dated between AH 912-938/1506-32 AD (Mehdi Bayani, Ahval va Asar-e Khosh-Nevisan, Vol. I, Tehran, 1345 sh., pp.272-9).
An album of calligraphy and painting, compiled by Dust Muhammad in 1544 for the Safavid Prince Bahram Mirza, contained thirty signed specimens of Sultan Muhammad's calligraphy, many of which were written on paper of different colours (now in the Topkapi Saray Library, H.2154, published in David J. Roxburgh, The Persian Album 1400-1600, Yale 2005, pp.245-307). In the introduction Dust Muhammad lavishes praise on Sultan Muhammad for his 'accomplishment and purity' as a scribe and stresses his special expertise in writing with coloured inks, as in the present example (Jon Thompson and Sheila R. Canby (eds.), Hunt for Paradise: Court Arts of Safavid Iran 1501-1576, New York and Milan, 2003, p. 52).
