"For samples of organic decay of the chest defined tissue, which was buried sew clothes (studies performed ES Zubkova and OV Orfinskoy). Was able to establish four types of textiles of various colors and types of binding. In the records and annotations of materials are listed as red-brown silk fabric ( «samid»), thick woolen sarzhevogo mixing red, blue linen cloth binding and non-woven textiles of vegetable origin ( «bat»). Some fragments are preserved, and traces of the seam pattern. EA Yakovleva suggests that the burial clothes were of cotton. As the author writes in his report «bat», probably used in a quilted warm clothing, as well as stratigraphically located between two layers of tissue, and, on top «sarafan» In addition, in the layer were found separate cotton fibers and indeterminable plant fibers. Sample decay of the board, the underlying bone, showed the presence of remnants of red woolen cloth."
I suspect "samid" should be translated as "samite", a weave characteristic of Eastern silks of the period. The presence of cotton clothes, if confirmed, is very interesting indeed. However, it's possible that the "cotton" in question was only cotton batting, used in the "quilted warm clothing"--a use found during the medieval period in Europe much earlier and more commonly than woven cotton cloth.
The red and blue color scheme, on the other hand, appears in other prestigious burials of the Migration Period and in the early medieval period. Indeed, it is shared by the other Pskov textile find, the one including the apron dress remnant.
