describing the currencies of the Yuan Empire around the year 1300. An Italian merchant's handbook dated about 1340, Pratica della mercatura by Pegolotti, used the term bisant for coins of North Africa (including Tunis and Tripoli), Cyprus, Armenia and Tabriz (in today's northwestern Iran), whereas it used the term perpero / pipero for the Byzantine bizant. Although the medieval "bezant" usually referred to a gold coin, some medieval Latin texts have been noted to expand its usage to cover silver coins. These silver bezants were often called "white bezants". Occasionally in Latin they were also called "miliaresion bezants" / "miliarense bezants". Like the gold bezants, the silver bezants by definition were issuances by the Byzantine government or by an Arabic government, and not by a Latin government, and the usage of the term was confined to the Latin West. Bezants in heraldry In heraldry, a roundel of a gold colour is referred to as a bezant, in reference to the coin. Like many heraldic charges, the bezant originated during the crusading era, when Western European knights first came into contact with Byzantine gold coins, and were perhaps struck with their fine quality and purity. During the Fourth Crusade the city of Constantinople was sacked by Western forces. During this sacking of the richest city of Europe, the gold bezant would have been very much in evidence, many of the knights no doubt having helped themselves very liberally to the booty. This event took place at the very dawn of the widespread adoption of arms by the knightly class, and thus it may have been an obvious symbol for many returned crusaders to use in their new arms. When arms are strewn with bezants, the term bezantée or bezanty is used. References External link Coins Gold coins Coins of the Byzantine Empire Heraldic charges
