This contribution intends to present some Umayyad and ‘Abbasid glass stamps, from a
large private collection, probably made in Egypt during the 8th-9th century AD,
supposedly by the office of weights and measures (d!r al-‘iy!r). Some of them name
people that are well known from historical sources (Caliphs, Governors, Finance
Directors...), others bear less known names (of executives and, especially, of artisans of
Coptic origins). Last but not least, the group also contains anonymous exemplars, as
well as disks with pious formula or crude imitative legends.
