Ivughli, a secretary (munshi) at the Safavid court, compiled this collection of correspondence (majmu‘a-i munsh’at) sent by Persian rulers, from the Great Seljuks in the eleventh century to the Safavid shah Safi I (reigned 1629–42). In Iran, the art of letter writing was as much esteemed as eloquence and rhetoric. Penned in neat shikasta nasta‘liq (“brokennasta‘liq”), the text alternates between paragraphs written horizontally and diagonally from the right or the left.
One letter of particular interest is on the left-hand page. Composed by the Timurid ruler Sultan Husayn (reigned 1469–1506), it is addressed to the celebrated calligrapher Sultan Ali Mashhadi (died 1520). The sovereign reprimands the calligrapher for making too many mistakes when copying poems written in Turkish, the language Sultan Husayn used for his own poetry. (via)
