A Cairene carpet border fragment, Ottoman Egypt,

For a closely related border fragment  see: Kühnel, Ernst and Bellinger, Louisa, Cairene Rugs and others Technically Related, 15th Century - 17th Century, The Textile Museum, Washington, D. C., 1957, pp. 57 and 61, pls. XXXIV and XXXVII, R 1.114. 

The Textile Museum example is described as having borders (or minor borders if a border fragment from a large carpet) originally adjacent  to the field (or main border if a border fragment)  on both sides and on one end, therefore the authors have assumed that it was woven in a runner format, although probably originally longer.  Even though the Textile Museum piece is longer than the current lot they are approximately the same width and may have been woven on the same loom if originally both were woven as runners or salvaged from the same carpet if border fragments.

The presence of a small number of related carpet fragments where this border treatment appears along with sections of the main field, would suggest that these fragments all originate from the same carpet or group of carpets woven after the same cartoon.  Two of these fragments are illustrated in Spuhler, Friedrich, Oriental Carpets in The Museum of Islamic Art, Berlin,  Washington, D. C., 1987, pp. 61, 208 and 209, Nos. 65 and 66 (Inv. Nos. 89, 150 and 97, 58) and another two in Kühnel & Bellinger (op. cit.), pls. XXXVIII and XXXIX. There is another fragment, also probably from the same carpet, in the Kestner Museum, Inv.No.5424, see von Gladiss, Almut, Islamische Teppiche und Textilien, Hannover, 1987, Nr.1, p.9.

The attribution of  this group of Ottoman Cairene group to Egypt is a subject of lively debate.  Such carpets were undoubtably woven in the Turkish Court Style rather than in the Mamluk model. This example, the Textile Museum 'runner' and the corner fragment from Berlin (Spuhler (op. cit.) No. 65) each display a repeated çintamani motif within the guard stripes, a symbol closely associated with Anatolian production.  According to Spuhler (ibid.), p. 58-9, in 1585 Sultan Murad III summoned eleven master weavers from Cairo who brought their skills and materials to Istanbul. Although technically these fragments are Egyptian in structure they may have been produced in Istanbul or Bursa by Egyptian artisans.
