The Arte della Lana was the wool guild of Florence during the Late Middle Ages and in the Renaissance. It was one of the seven Arti Maggiori ("greater trades") of Florence, separate from the Arti Minori (the "lesser trades") and the Arti Mediane (the "middle trades"). The Arte della Lana dealt in woollen cloth and cooperated with the other corporations of bankers and merchants in administering the commune, both under the podestà and the Republic of Florence. The powerful Albizzi family were prominent members of the guild.[1]
