Also 5–7 bissus.
[a. L. byssus, a. Gr. βύσσος ‘a fine yellowish flax, and the linen made from it, but in later writers taken for cotton, also silk, which was supposed to be a kind of cotton’ (Liddell & Scott), ad. Heb. būts, applied to ‘the finest and most precious stuffs, as worn by kings, priests, and persons of high rank or honour’ (Gesenius), transl. in Bible of 1611 ‘fine linen’, f. root *būts, Arab. bāḍ to be white, to surpass in whiteness. Originally therefore a fibre or fabric distinguished for its whiteness.]
1. An exceedingly fine and valuable textile fibre and fabric known to the ancients; apparently the word was used, or misused, of various substances, linen, cotton, and silk, but it denoted properly (as shown by recent microscopic examination of mummy-cloths, which according to Herodotus were made of βύσσος) a kind of flax, and hence is appropriately translated in the English Bible ‘fine linen’.
