Rectangular stucco and glass window composed of three fields with ornamental decoration. The centre field shows an almond-shaped, orange-coloured opening framed by two bands featuring single-arch shapes, and a third of alternating single- and double-arch shapes. The two flanking fields show the motif of an eight-pointed double star inscribed within a circle. The spaces between the points of the star are filled with red, petal-like forms.

The stars as well as the central motif are set within a background of more or less regularly spaced perforations.

Coarse-grained (yellowish) gypsum plaster; colourless glass (partly with a greyish tint); coloured glass (three shades of green, four shades of blue, three shades of yellow, including a bright-orange piece replaced in 2003); several shades of red flashed glass

The window is well preserved and was thoroughly restored in 2003. During this intervention, earlier repairs such plaster fillers and metal reinforcements were removed. The restoration measures included the removal of the 2–3mm-thick coat of red paint; cleaning the surface of the stucco lattice (laser cleaning, density: 1.5 J/cm2 at 1064nm), bonding cracks with acrylic resin, and filling lacunae in the stucco lattice with acrylic filler. The repairs were retouched with pigmented acrylic emulsion. In addition, fragile areas were strengthened with gauze and acrylic resin. The original wooden frame was cleaned with solvent and reinforced by adding an aluminium frame.

At the time of restoration, around 80% of the original pieces of glass were preserved. Missing pieces were replaced with new ones, which were attached with cellulose nitrate.

While there are several examples of the star motif in Western museums (see for instance IG_166, IG_186, IG_353), the almond-shaped ornament in the centre of the window is not present in any of the collections studied.

From a technical point of view, it can be assumed that the window was made in an Egyptian workshop. Although the rear of the window was not accessible during our examination, it can be concluded from the restoration report of 2004 that the window was made according to the traditional technique used in the manufacture of qamariyyāt in North Africa to this day (see Technique).

According to the museum records, the window dates to the 16th or 17th century. However, its relatively good state of preservation suggests that it was made in the 19th rather than in the 16th or 17th century. If the window had been installed in a building and been exposed to outside conditions for two or three centuries, we would have expected it to be more heavily weathered before its restoration in 2003.

While part of the sheet glass may have been recycled from locally produced crown glass (purple glass), the majority of the glass used in this window may have come from European glassworks, as according to the Hungarian architect Max Herz (1856–1819), the production of sheet glass in Egypt had come to a standstill in the 19th century (Herz, 1902, p. 53). This is supported by the fact that many of the pieces of glass show structures that suggest that the glass was produced using the broad-sheet method. This technique was uncommon in the Islamic world at that time and more commonly used in Europe.

The Cairo-based, Cypriot art and antique dealer Phokion Tanos (1898–1972) donated this window – along with 12 other qamariyyāt (11049–11059, 20969, 20960, see IG_336–359) – to the Benaki Museum in Athens, probably in the 1940s.
