Article on eighteenth- and early nineteenth-century Polish silk and metal-thread sashes (Persiarnia belts) made in the Persian style. It surveys the factories at Sluck and Kobylka and their directors and signatures, then the minor factories at Cracow, Dantzig and elsewhere. It discusses design (floral and geometric stripes, side and end borders), colors, and technique (compound cloth, selvage treatment). Nine plates show belt ends signed by various makers; no weaving drafts are included.
