Samite

Samite was a luxurious and heavy silk fabric worn in the Middle Ages, of a twill-type weave, often including gold or silver thread. The word was derived from Old French samit, from medieval Latin samitum, examitum deriving from the Byzantine Greek ἑξάμιτον hexamiton "six threads", usually interpreted as indicating the use of six yarns in the warp. Samite is still used in ecclesiastical robes, vestments, ornamental fabrics, and interior decoration.
