Page with illustrations in Julius Franz, Die Baukunst des Islam, 2nd ed., 1896, p. 69, figs 78, 79. The illustrations show a stucco and glass window and the technique for cutting their stucco profiles.
The round-arched qamariyya shows a pattern of curlicues and flowers.

This page in Julius Franz’ second edition of Die Baukunst des Islam shows four illustrations, two already known from the first edition. A new technical drawing (fig. 79) demonstrates how the pieces of coloured glass were attached by means of ‘Gypswürstchen’ (strips of plaster, marked with a ‘b’) on the reverse of the stucco plate (Franz, 1896, pp. 67–68). This method was also described by Max Herz (1895, p. 8; see IG_160), shortly before the publication of the second edition, as the older of two techniques for the production of stucco and glass windows.
Furthermore, a photograph newly added for the second edition shows a qamariyya with a pattern of curlicues and flowers. The same qamariyya appears on one of Beniamino Facchinelli’s photographs (IG_205) of the collection of the Museum of Islamic Art in Cairo, which was still located in the Al-Hakim Mosque at the time. A window with identical design is preserved in The Metropolitan Museum in New York since 1893 (IG_169).
