Troy Oz
Troy weight is a system of units of mass that originated in the Kingdom of England in the 15th century and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of the avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. Legally, one troy ounce (oz t) equals exactly 31.1034768 grams. Etymology Troy weight is generally supposed to take its name from the French market town of Troyes where English merchants traded at least as early as the early 9th century. The name ''troy'' is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize of Weights and Measures'' (also known as ), one ...

Aes Grave
''Aes grave'' ("heavy bronze") is a term in numismatics indicating bronze cast coins used in central Italy during the 3rd century BC, whose value was generally indicated by signs: I for the as, S for semis and pellets for unciae. Standard weights for the as were 272, 327, or 341 grams, depending upon the issuing authority. The main Roman cast coins had these marks and images: __NOTOC__ Issuing cities Main series were from Rome, Ariminum (Rimini), Iguvium (Gubbio), Tuder ( Todi), Ausculum (Ascoli Satriano), Firmum ( Fermo), Hatria - Hadria (Atri), Luceria (Lucera), and Latin central Italy.

Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Roman Currency
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum#Numismatics, orichalcum and copper coinage. From its introduction during the Roman Republic, Republic, in the third century BC, through Roman Empire, Imperial times, Roman currency saw many changes in form, denomination, and composition. A feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued with Byzantine currency. Due to the economic power and longevity of the Roman state, Roman currency was widely used throughout western Eurasia and northern Africa from classical times into the Middle Ages. It served as a model for the currencies of the List of Muslim states and dynasties, Muslim caliphates and the European states during the Middle Ages and the Modern Era. Roman currency names survive today in many countries via the Carolingian monetary system, such as the dinar (from the ''denari ...

Champagne Fairs
The Champagne fairs were an annual cycle of trade fairs which flourished in different towns of the County of Champagne in Grand Est, Northeastern France in the 12th and 13th centuries, originating in local agricultural and stock fairs. Each fair lasted about two to three weeks. The Champagne fairs, sited on ancient land routes and largely self-regulated through the development of the ''Lex mercatoria'' ("merchant law"), became an important engine in the reviving economic history of medieval Europe, "veritable nerve centers" serving as a premier market for textiles, leather, fur, and spices. At their height, in the late 12th and the 13th century, the fairs linked the cloth-producing cities of the Low Countries with the Italian dyeing and exporting centers, with Genoa in the lead,Elspeth M.

English Units
English units were the units of measurement used in England up to 1826 (when they were replaced by Imperial units), which evolved as a combination of the Anglo-Saxons, Anglo-Saxon and Ancient Roman units of measurement, Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications. Use of the term "English units" can be ambiguous, as, in addition to the meaning used in this article, it is sometimes used to refer to the units of the descendant Imperial system as well to those of the descendant system of United States customary units. The two main sets of English units were the Winchester measure, Winchester Units, used from 1495 to 1587, as affirmed by Henry VII of England, King Henry VII, and the Exchequer Standards, in use from 1588 to 1825, as defined by Queen Elizabeth I. In England (and the British Empire), English units were replaced by Imperial units in 1824 (effective as of 1 January 1826) ...

Auncel
The auncel ( or ', "little balance") was a steelyard balance scale formerly used in England. It consisted of a rod with the fulcrum near one end and a weight that could be moved along the graduated longer arm. The item to be weighed was hung from the end of the shorter arm of the rod. This design made it easier for merchants to falsify the weight than when scales with arms of equal length were used, as a result of which it was bannedJames Davis. Medieval Market Morality: Life, Law and Ethics in the English Marketplace, 1200–1500. Cambridge University Press. 2011. p.195. by Edward III in 1350.

Steelyard Balance
A steelyard balance, steelyard, or stilyard is a straight-beam Weighing scale, balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. Structure The steelyard comprises a balance beam which is suspended from a lever/pivot or fulcrum which is very close to one end of the beam. The two parts of the beam which flank the pivot are the arms. The arm from which the object to be weighed (the load) is hung is short and is located close to the pivot point. The other arm is longer, is graduated and incorporates a counterweight which can be moved along the arm until the two arms are balanced about the pivot, at which time the weight of the load is indicated by the position of the counterweight. Mechanism The steelyard exemplifies the lever, law of the lever, wherein, when balanced, the weight of the object being weighed, mul ...

Weighing Scale
A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances, massometers, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while objects of known mass or weight, called '' weights'', are added to the other plate until mechanical equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. The perfect scale rests at neutral. A spring scale will make use of a spring of known stiffness to determine mass (or weight). Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness (or spring constant). The heavier the object, the more the spring stretches, as described in Hooke's law. Other types of scales making use of different physical principles also exist. Some scales can be calibrate ...

Edward I Of England
Edward I (17/18 June 1239 – 7 July 1307), also known as Edward Longshanks and the Hammer of the Scots (Latin: Malleus Scotorum), was King of England from 1272 to 1307. Concurrently, he was Lord of Ireland, and from 1254 to 1306 ruled Duchy of Gascony, Gascony as Duke of Aquitaine in his capacity as a vassal of the French king. Before his accession to the throne, he was commonly referred to as the Lord Edward. The eldest son of Henry III of England, Henry III, Edward was involved from an early age in the political intrigues of his father's reign. In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciling with his father, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was held hostage by the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1 ...
