Sabzavar is the most probable source of the great vase carpets of the Sixteenth century. I realize that such leading luminaries as the late Charles Grant Ellis and the late Dr. May Beattie have suggested Kerman as the source but I have to disagree. Technically and stylistically we have three interrelated groups that musty be viewed as a whole. First there are Vase Carpets which are clearly related to Sanguszko Carpets and Sanguszko Carpets are clearly related to some of the so-called Salting Carpets. I suggest that Vase carpets and Sanguszko carpets must come from the same sixteenth century source. Further I suggest that Sanguszko Carpets are Court Carpets and must be the product of a court manufactory. There was no court and there was no court manufactory in Kerman in the Sixteenth century. There was no court manufactory in Kerman until at least the reign of Abbas Safavi the great. Obviously the Sanguszko carpets are clearly earlier and therefore cannot be from either the court artists of Abbas Safavi or Kerman.
By the way I am not suggesting that Salting Carpets came from Sabzavar. However if we follow Persian history from the death of Soltan Ibrahim Mirza whose court produced the Vase carpets then it becomes obvious where the Salting Carpets must have been made.
