The text is: surah Luqman (XXXI), verse 6. Copied in seven lines per page, on one side only of enormous sheets of paper (almost 177 cm x 101 cm), the so-called 'Baysunqur Qur'an' must have amounted to almost 800 double page spreads. Baysunqur, a son of the Timurid ruler Shah Rukh (r.1405–1447), was a famous bibliophile, calligrapher and designer of inscriptions. Even if he had succeeded in writing ten lines a day to the very exacting standard exemplified by this single line, it would have taken him at least 18 months to complete the volume, and the feat could not have passed without remark in contemporary chronicles. An alternative authorship is suggested by the Qadi Ahmad Qummi (c.1605). The Samarkand calligrapher 'Umar Aqta', who was one-handed and left-handed at that, had written a Qur'an for Tamerlane that was so small it would fit under the bezel of a signet ring.
