The attribution to the western Mediterranean is based on comparison with leaves which have been ascribed to Andalusia on the basis of the use of the Maghribi abjad markers in the ‘ashr rosette. A Qur’an section offered at Christie’s, 2 May 2019 lot 2, of similar dimensions and with the same number of lines to the page, presented comparable ‘ashr markers consisting of golden rosettes encircling a letter outlined in black. In that section the number sixty is indicated with the letter sad instead of the letter sin, which might suggest that it was copied in the Western Mediterranean (Fraser & Kwiatkowski 2006, p.44). The ‘ashr marker on this leaf used the letter lam to indicate the numeral thirty, standard for both Eastern and Maghribi numerical values (Déroche 2015, p.96).
