Great credit is due Dr. Wm. R. Valentiner and his assistants for the promotion and successful management of this exhibition. Let us hope that it is but the beginning of a series of such exhibits which will stimulate a more formal interest and desire to know more about these wonderful products of the Eastern loom.
The age of old rugs can be at least as accurately determined as the age of old paintings and in many cases even more so. According to Dr. Valentiner the so-called Polanaise and Ispahan rugs belong to the 17th century and the Persian animal or hunting rugs belong to the 16th century, while the so-called dragon rugs belong to the 15th century. Many of the rugs from Armenia and the eastern part of Asia Minor date back as far as the 13th and 14th centuries.

Every old rug has its individual character manifest by its designs, colors, weave, and material, all of which are peculiar to the time when it was made or the locality in which it was made, so that it can be located and dated with greater accuracy than would be supposed.

Many early rugs were used for decorative purposes in the pictures of the early Italian and Flemish painters.

According to recognized authorities the so-called Polish carpets were not woven in Poland at all, but were products of Persia, and the so-called Ispahan rugs were not made at Ispahan or even in Persia, but came from the city of Herat in Western Afghanistan. Of the former several hundred are still in existence, the best of which are in the European courts and museums, about forty being in the United States, while nearly every collection contains one or more of the Herats.
THE ARDEBIL CARPET.--Without a doubt the most famous Oriental carpet now known is the mosque carpet of Ardebil owned by the South Kensington Museum in London.
It is a Persian masterpiece and was made in 1536 by one Maksoud for the Ardebil Mosque. In size it is thirty-four and one-half by seventeen and one-half feet and contains in the neighborhood of 32,000,000 knots, about 530 to the square inch, and was purchased by the South Kensington Museum for $12,500, although, if put up at auction to-day, it would doubtless bring many times that sum. The ground is of a rich blue and is covered with the most intricate of old Persian floral designs. It has a central medallion in pale yellow with corners to match. There are three border stripes, one wide one with a narrow one on either side of it. The ground of the outer stripe is of a tawny yellow with small floral designs; the ground of the inner stripe is cream colored and that of the main stripe is of a rich brown with round and elongated panels alternating and surrounded by a profusion of floral lines. Within these panels are to be found in Arabic the following inscription: "I have no refuge in the world other than thy threshold; My head has no protection other than this porch way; The work of the slave of the Holy place, Maksoud of Kashan." In the year 942 (which corresponds to A.D. 1536.)[B]
