Album folio  

This elaborate folio presents four calligraphic panels (clockwise from upper left): two unsigned couplets; three couplets copied by Sultan Mahmud; two couplets by Shah Muhammad; and two couplets by Sultan Muhammad Nur. Writing in gold in the triangle above his work, Sultan Muhammad Nur states he penned this example by imitating the style of “Mawlana [our master] Sultan Ali al-Mashhadi.” The unsigned couplets in the upper left corner could well be the work of Sultan Ali Mashhadi. Its carefully modulated line and the visual balance between fluid and disciplined strokes are indeed distinctive of his work. Also, combining Sultan Ali Mashhadi’s calligraphy with examples by three of his outstanding students on a single page underscores the fundamental importance of the master-pupil relationship.
