The craft charters
Central Asian craft trades had charters known as risola. Writing in San’at, a magazine of the Academy of Arts of Uzbekistan, in 2009, Dilyara Atajanova says the rite of making a master, called kamar band, kamar baste or ona miyon band, was described, and so kept, in these charters. For the weavers she cites four manuscript copies of their charter, the Risola-i bofandagi, held by the Institute of Oriental Studies of the Uzbek Academy of Sciences. In Persian, kamar means ‘waist’ and band means ‘fasten’; the same word, kamarband, reached English as cummerbund.
To verify: How old the surviving risola manuscripts are; What Jeanine Elif Dagyeli’s 2011 book on the craft risola, Gott liebt das Handwerk, says about the rite: we have not yet been able to open it
