Heredium (unit Of Measure)
The jugerum or juger (, ', ', or ') was a Roman unit of area, equivalent to a rectangle 240 Roman feet in length and 120 feet in width (about 71×35½m), i.e. 28,800 square Roman feet () or about hectare (0.623 acre). Name It was the double of the , and from this circumstance, according to some writers, it derived its name. It seems probable that, as the word was evidently originally the same as , a yoke, and as , in its original use, meant a path wide enough to drive a single beast along, that originally meant a path wide enough for a yoke of oxen, namely, the double of the in width; and that when was used for a square measure of surface, the , by a natural analogy, became the double of the ; and that this new meaning of it superseded its old use as the double of the single . Pliny the Elder states: That portion of land used to be known as a "jugerum," which was capable of being ploughed by a single "jugum," or yoke of oxen, in one day; an "actus" being as much as ...

Ancient Roman Units Of Measurement
The units of measurement of ancient Rome were generally consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' (plural: ''pedes'') or Roman foot. Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot, and reported these values compared to the iron standard of the English foot in the Guildhall in London William Smith (1851) gives a value ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Acre
The acre ( ) is a Unit of measurement, unit of land area used in the Imperial units, British imperial and the United States customary units#Area, United States customary systems. It is traditionally defined as the area of one Chain (unit), chain by one furlong (66 by 660 Foot (unit), feet), which is exactly equal to 10 square chains, of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the International yard and pound, international yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres. The acre is sometimes abbreviated ac, but is usually spelled out as the word "acre".National Institute of Standards and Technolog(n.d.) General Tables of Units of Measurement . Traditionally, in the Middle Ages, an acre was conceived of as the area of land that could be ploughed by one man using a team of eight oxen in one day.

Yoke
A yoke is a wooden beam used between a pair of oxen or other animals to enable them to pull together on a load when working in pairs, as oxen usually do; some yokes are fitted to individual animals. There are several types of yoke, used in different cultures, and for different types of oxen. A pair of oxen may be called a ''yoke of oxen'', and yoke is also a verb, as in "to ''yoke'' a pair of oxen". Other animals that may be yoked include horses, mules, donkeys, and water buffalo. Etymology The word "yoke" is believed to derive from Proto-Indo-European *yugóm (yoke), from root *''yewg''- (join, unite), and is thus cognate with '' yoga''. This root has descendants in almost all known Indo-European languages including German ''Joch'', Latin ''iugum'', Ancient Greek ζυγόν (''zygon''), Persian یوغ (''yuğ''), Sanskrit युग (''yugá''), Hittite 𒄿𒌑𒃷 (iúkan), Old Church Slavonic иго (''igo''), Lithuanian ''jungas'', Old Irish ''cuing'', and Armenian ...

Pliny The Elder
Gaius Plinius Secundus (AD 23/24 79), known in English as Pliny the Elder ( ), was a Roman Empire, Roman author, Natural history, naturalist, and naval and army commander of the early Roman Empire, and a friend of the Roman emperor, emperor Vespasian. He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is Lost literary work, no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used ''Bella Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plethron
Plethron (, plural ''plethra'') is an ancient unit of Greek measurement equal to 97 to 100 Greek feet (ποῦς, ''pous''; c. 30 centimeters), although the measures for plethra may have varied from polis to polis. This was roughly the width of a typical ancient Greek athletic running-track. A plethron could also be used as a unit of measured area, and reference to the unit in defining the size of a wrestling area is made by Libanius.Libanius, '' Orationes'', Chapter 10. A square plethron of c. 30 by 30 meters was used as the standard dimensions of a Greek wrestling square, since such competitions were held within the racing track in ancient Greece. In other connotations, it functioned as the Greek acre, and varied in size to accommodate the amount of land a team of oxen could plow in a day. The plethron continued to be used in the Byzantine Empire, where its variant uses were ultimately codified to refer to an area defined by sides of 100 feet or 40 paces (βῆμα, bema). Se ...

Centuria (unit Of Measure)
During centuriation (Ancient Roman land surveying), centuria was a basic unit of area, representing a square of 20 actus (710 meters, 2400 Roman feet) on a side (an area of about 50 hectares). The name derives from the fact that in new colonies each centuria can be subdivided into 100 lots of heredium size (equal to two jugera each, or about 0.5 hectare) that were typically allocated to 100 families of colonists. Although the "normal" size of centuria (20x20 actus = 200 jugera) was dominant, the contemporary Roman sources as well as modern archeological results suggest that centuria varied in size from 50 to 400 jugera, with some subdivisions using non-square plots. Written sources describe centuria as large as 80x16 actus = 640 jugera in Luceria, although Flach considers this record "not credible". Despite the Roman foot definitions varying by time and geography, the surviving centuriation divisions are consistent, with normal size centuria side measurements from 703 meters i ...

Roman Gaul
Roman Gaul refers to GaulThe territory of Gaul roughly corresponds to modern-day France, Belgium and Luxembourg, and adjacent parts of the Netherlands, Switzerland and Germany. under provincial rule in the Roman Empire from the 1st century BC to the 5th century AD. History During the Republic The Roman Republic's influence began in southern Gaul. By the mid-2nd century BC, Rome was trading heavily with the Greek colony of Massalia, Massilia (modern Marseille) and entered into an alliance with them, by which Rome agreed to protect the town from local Gauls, including the nearby Aquitani and from sea-borne Carthaginians and other rivals, in exchange for land that the Romans wanted in order to build a road to Hispania to improve troop movements to its provinces there. The Mediterranean settlements on the coast continued to be threatened by the powerful Gallic tribes to the north and in 122 BC the Roman general Gnaeus Domitius Ahenobarbus (consul 122 BC), Gnaeus Domitius Ahe ...

Arpent
An arpent (, sometimes called arpen) is a unit of length and a unit of area. It is a pre-metric French unit based on the Roman ''actus''. It is used in Quebec, some areas of the United States that were part of French Louisiana, and in Mauritius and the Seychelles. Etymology The word ''arpent'' is believed to derive from the Late Latin ''arepennis'' (equal to half a '' jugerum''), which in turn comes from the Gaulish *''are-penno''- ("end, extremity of a field"). Unit of length There were various standard arpents. The most common were the arpent used in North America, which was defined as 180 French feet (', of approximately ), and the arpent used in Paris, which was defined as 220 French feet. * In North America, 1 arpent = 180 French feet = about 192 English feet = about 58.47 metres * In Paris, 1 arpent = 220 French feet = about 234 English feet = about 71.46 metres Unit of area Historically, in North America, 1 (square) arpent ('), also known as a French acre, was 180 ...
