Ibn Muqla: Canonical Calligraphy Specimen (al-khat al-mansub), c.900–930 CE
A surviving example of Abbasid-era Arabic calligraphy in the proportional cursive system (al-khat al-mansub) codified by Ibn Muqla (886–940 CE). The system — based on the rhombic dot and a proportional circle — rationalized all six classical Arabic scripts and became the foundation of the entire subsequent calligraphic tradition. Key holdings: Chester Beatty Library, Dublin; Biblioteca Apostolica Vaticana, Rome.
Scholarly Significance
Anchor the Abbasid-era calligraphy tradition in the graph. Ibn Muqla's proportional script system is the founding event of classical Arabic calligraphy — as foundational to Islamic visual culture as Vitruvius to classical architecture.
Patronage Context
Ibn Muqla served as Grand Vizier under three Abbasid caliphs (Al-Muqtadir, Al-Qahir, Ar-Radi). His calligraphic works would have been produced within the Abbasid court administration and personal practice.
