Blue Qur'an The Blue Qur'an (Arabic: المصحف الأزرق "al-Muṣḥaf al-′Azraq") is a late 9th- to early 10th-century Fatimid Tunisian Qur'an manuscript in Kufic calligraphy, probably created in North Africa for the Great Mosque (Mosque of Uqba) of Qairawan. Although scholars generally agree on its provenance and dating, recent scholarship by Alain George dates the manuscript rather earlier, to the early Abbasid caliphate; however, it has been dated as late as 1020 CE and placed in Córdoba as well as Qairawan. It is written in gold and decorated in silver (that has since oxidized) on vellum colored with indigo, a unique aspect of a Quranic manuscript, probably emulating the purple parchment used for Byzantine Imperial manuscripts. Red ink is also used. It is among the most famous works of Islamic calligraphy, and has been called "one of the most extraordinary luxury manuscripts ever created." Art historian Yasser Tabbaa wrote that the "evanescent effect" of the gold lettering on indigo "appears to affirm the Mu'tazili belief in the created and mysterious nature of the Word of God."
