The English term cordwainer, meaning shoemaker, first appears in 1100. By the late 13th century a distinction grew in England between Cordwainers. proper, called alutari, who used only alum "tawed" cordwain, and another class of shoemakers called basanarii, who employed an inferior "tanned" sheepskin which was prohibited for footwear apart from long boots. Since this period the term cordouan, or cordovan leather, has been applied to several varieties of leather. Today cordovan leather is a "vegetable tanned" horse "shell," and like the Medieval cordwain is used only for the highest quality shoes.
