There is a piece of very old Byzantine silk in the Kensington Collection, and also a piece of the same material in the Silk Museum at Lyons, which consists of a design of winged personages wrestling with lions; the pattern is woven in strips, and the colour is a red ground with white, gold-coloured, blue and green figuring. The style of the design and peculiarity of the weaving prove it to be of a date anterior to the eighth century. This particular Byzantine tissue has the red weft of the ground executed in five different shades of the red colour thrown crosswise (_lancé croisé_), each shade alternating in three threads by three; the warp is thick, and the shuttle passes right across the width, all the material being pure silk—these are the marks by which Byzantine fabrics are known. [Illustration: Fig. 259.—Assyrian Homa or Sacred Tree.] [Illustration: Fig. 260.—Tree of Life, Assyrian.] It is only in genuine examples of Byzantine Greek fabrics where we find the human figure is used in the design, or animals of a free and natural type, as the Byzantine silk designs were invariably taken from Greek mythological sources and scriptural subjects. Genuine examples of Byzantine fabrics are very scarce, and the one described is a genuine example of great value. When the Arabs under Mohammed had conquered the countries of Persia, Syria, and the countries south of the Persian Sea, they found already in these places the manufacture of silk in a flourishing state. From this time—the ninth century—until the fourteenth, we find that from the borders of China and India in the east to Africa and Spain in the south and west—which embraces the countries conquered by the Saracens—the silk industry was carefully fostered under the Mohammedan rule. Next to precious stones in importance and value the chiefest treasures of the Khalifs of Bagdad, Cairo, Fez, and Cordova were silken goods. The bazaars of the chief towns were filled with the precious material, and silk fairs or markets were held periodically, chiefly at Antioch, Rey, Erzeroum, Ispahan, Jerusalem, and Mecca. The Mussulman laws forbade the faithful to negotiate with the (Christian) infidels, but there was a saving clause that helped them out of this difficulty, which allowed them to bargain with the Jews, and these middlemen did not scruple to do business with either the Christian infidel or Mussulman. The Jews were then, as they are now, the bankers, merchants, and dealers in silk and precious stones, and even before this date they were the purveyors of all kinds of articles of luxury to the wealthy Romans of the south, the Gallo-Romans of the west, and the Goths of Northern Europe.
