The calligraphy of the leaves corresponds to Déroche's 'group B' in his categorisation of early Arabic scripts used for copying the Qur'an (Déroche, 1992, pp.34-47). However, whilst other manuscript leaves on vellum share a similar script (see, for example, a single folio in the Nasser D. Khalili Collection, London (No. KFQ28), ibid, p.54, no.8), nothing is known of this monumental size from the ninth century onwards. Even the so-called 'Nurse's Qur'an', arguably the most magnificent example of western Kufic, is only half the width of the present leaves, although roughly the same in height. Perhaps the closest comparable known in the canon of Kufic Qur'ans on vellum is that of the eighteen-line manuscript whose leaves measure roughly forty by fifty-four centimetres. Although the pages share the same number of text lines as the present leaves, the text is more cramped with a less obvious stretching of the individual letter forms (mashq). Various leaves from that particular manuscript are known, including one exhibited in the exhibition Ink and Gold - Islamic Calligraphy at the Museum für Islamische Kunst in Berlin in 2006 (see Fraser and Kwiatkowski 2006, pp.34-37, no.6), whilst others were sold in these rooms 14 April 2010, lot 3; 6 April 2011, lot 166; 1 April 2009, lot 3 and 8 October 2008, lot 7.

Two other leaves from the same Qur’an were sold in these rooms, 20 April 2016, lots 4 and 5.
