Alnage
（重定向自Alnager）
Alnage, or aulnage (from Fr. aune, ell) is the official supervision of the shape and quality of manufactured woollen cloth.
It was first ordered in the reign of Richard I that "woollen cloths, wherever they are made, shall be of the same width, to wit, of two ells within the lists, and of the same goodness in the middle and sides." This ordinance is usually known as the Assize of Measures or the Assize of Cloth. Article 35 of Magna Carta re-enacted the Assize of Cloth, and in the reign of Edward I an official called an "alnager" was appointed to enforce it. His duty was to measure each piece of cloth, and to affix a stamp to show that it was of the necessary size and quality.
