The person from whom I acquired this yastik represented that it was knotted in the 18th century; regardless, I liked it and bought it.
The design, of course, is classic and is typically attributed to Central Anatolia.
However, I remained curious about its age and decided to research it further.
Fortunately, this is a design group with many surviving examples of varying quality and age.
I assembled a group of seven yastiks which were accepted as being knotted in the 19th century and was compositionally similar to my newly acquired one.
Two of the group are published in Morehouse's Yastiks (#55 and #56).
Two appear in the auction catalogs of Chrisitie's NYC/April, 1990 and Rippon Boswell/Wiesbaden/May, 1989.
The other three are in private collections and unpublished. I handled them but was unable to obtain photographs.
Although not extremely large, the study group was of sufficient size to allow meaningful comparisons and to track changes in the base composition and specific motifs.
For this inquiry it is instructive to compare the yastik posted here to the four photographed and published examples mentioned above.
Stylistically, one sees a degenerative process in the field and lappet areas of each of the assumed 19th century yastiks (hereafter referred to as 19th century).
This process is evidenced by the over-abundance of secondary or filler motifs in the field.
In the 19th century examples the sizing of motifs is often miscalculated.
The dimensions of the border and lappet panels are too large and impose on the field.
With these miscalculations come a lack of design balance and fluidity.
In turn, the border and lappet motifs themselves are over-sized and in combination visually challenge the field composition still further.
In comparison, these flaws of design and execution are absent in the presumed 18th century yastik.
In the end, it is concluded that this posted yastik is compositionally distinguishable from and aesthetically superior to its extended family of 19th century copies and was within a reasonable degree of certainty knotted in the 18th century.
