The textile can be found in the Victoria and Albert Museum, dated during the Mamluk era in Egypt. It is plain woven linen embroidered in double running stitch using silk. The Museum states it was found in El-Azam, or Upper Egypt.
I have charted the design for use. In it I have also broken down the repeated main motif, which should help the main complex section. I also put in more of the smaller bands around the main motif, as there is a modern looking cut through the textile at the top & it is very likely the smaller bands would be repeated.
Let me know what you think!
