On the dating of Oriental Rugs:

Circa 1656 Tekke Juval

On the dating of Rugs:

“They can't all have been made in 1875, some must be older.” This bon mot from Harold Keshishian is as true today as the day he said it. For a number of reasons if a rug looks old dealers or auction houses have traditionally dated it to circa 1875. This is mainly because if a rug later is shown to have a chemical dye it is within the range where a chemical dye could have been used. So it is a safe attribution and a huge number of rugs got assigned an attribution of circa 1875. But in that group some are newer and conversely some must be older. We have reached a point where there are a growing number of rugs that considerably predate 1875.

Pioneering work by Jim Allen working with the Metropolitan Museum of Art as well as that of Dr. Jurg Rageth, c14 (radio carbon dating) became a tool in carpet studies. A growing number of rugs have been dated significantly earlier than 1800 and each discovery makes it possible to date other rugs in the time frame that at one point was thought impossible.

Once Jim Allen's 17th century Tekke Juval was dated Circa 1656 it made it possible for others to suggest a rug was of a certain date in relationship to other rugs. It has become what I call a marker rug. Since as far as I know it is the oldest Tekke weaving to date it allows people to use it as a marker in dating their Tekke weaving. More to come...
