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 ...

Centuriation
Centuriation (in Latin ''centuriatio'' or, more usually, ''limitatio''), also known as Roman grid, was a method of land measurement used by the Romans. In many cases land divisions based on the survey formed a field system, often referred to in modern times by the same name. According to O. A. W. Dilke, centuriation combined and developed features of land surveying present in Egypt, Etruria, Greek towns and Greek countryside. Centuriation is characterised by the regular layout of a square grid traced using surveyors' instruments. It may appear in the form of roads, canals and agricultural plots. In some cases these plots, when formed, were allocated to Roman army veterans in a new colony, but they might also be returned to the indigenous inhabitants, as at Orange (France). The study of centuriation is very important for reconstructing landscape history in many former areas of the Roman empire. History The Romans began to use centuriation for the foundation, in the fourth cen ...

Ancient Roman
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. At its hei ...

Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the land, terrestrial Plane (mathematics), two-dimensional or Three-dimensional space#In Euclidean geometry, three-dimensional positions of Point (geometry), points and the Euclidean distance, distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designated positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. A professional in land surveying is called a land surveyor. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, Satellite navigation, GNSS receivers, ...

Actus (unit Of Length)
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 of 0 ...

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 ...

Roman Colony
A Roman (: ) was originally a settlement of Roman citizens, establishing a Roman outpost in federated or conquered territory, for the purpose of securing it. Eventually, however, the term came to denote the highest status of a Roman city. It is also the origin of the modern term " colony". Characteristics Under the Roman Republic, which had no standing army, their own citizens were planted in conquered towns as a kind of garrison. There were two types: * Roman colonies, ''coloniae civium Romanorum'' or ''coloniae maritimae'', as they were often built near the sea, e.g. Ostia (350 BC) and Rimini (268 BC). The colonists consisted of about three hundred Roman veterans with their families who were assigned from 1 to 2.5 hectares of agricultural land from the ''ager colonicus'' (state land), as well as free use of the ''ager compascus scripturarius'' (common state land) for pasture and woodland. * Latin colonies (''coloniae Latinae'') were considerably larger than Roman coloni ...

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 ...

Luceria
Luceria is an ancient city in the northern Apennines, located in the comune of Canossa in the Province of Reggio Emilia, on the right bank of the river Enza. Toponym The name might derive from ''lucus'', which means "sacred grove". It is not clear if this was the proper name of the city or if it was called ''Nuceria''. The little stream which separates Canossa from San Polo d'Enza is still called the ''Rio Luceria'' today. The name of this stream is fairly old as it appears in the 1364 property records of Azzo da Correggio as ''Rivum Luxerae''. The Egyptian astronomer and mathematician Claudius Ptolemy (85-165 AD) describes the position of the city with great precision in his ''Geographia'', indicating the latitude and longitude according to the system he invented, but he calls it Nuceria. However, Luceria is the best-attested and most used name, even in official documents. History Luceria probably arose as a mercantile centre in the 4th century BC. It was located in ''G ...

Chott El Djerid
Chott el Djerid ( ') also spelled ''Sciott Gerid'' and ''Shott el Jerid'', is a chott, a large endorheic salt lake in southern Tunisia. The name can be translated from the Arabic into English as "Lagoon of the Land of Palms". Geography The bottom of Chott el Djerid is located between 15 and 25 meters (about 50 to 80 feet) above sea level. The lake's width varies widely; at its narrowest point, it is only across, compared to its overall length of . At times, parts of it appear in various shades of white, green and purple. The narrow eastward inlet of the chott is also known as Chott el Fejej. It is the largest salt pan of the Sahara Desert, with a surface area of over 7,000 km2 (some sources state 5,000 km2). The site has a typical hot desert climate. Due to the harsh climate with mean annual rainfall of below 100 mm and daytime temperatures sometimes reaching 50 °C (122 °F) or more during summer with dense solar radiation, water evaporates from the la ...

Emilia (region)
Emilia () is a historical region of northern Italy, which approximately corresponds to the western and the north-eastern portions of the modern regions of Italy, region of Emilia-Romagna, with the area of Romagna forming the remainder of the modern region. Etymology Emilia takes its name from the Via Aemilia, a Roman road constructed by the consul Marcus Aemilius Lepidus (consul 187 BC), Marcus Aemilius Lepidus in 187 BCE to connect Rimini with Piacenza. The name was transferred to the district (which formed the eighth Roman Italy#Augustan organization, Augustan region of Italy) as early as the time of Martial, in popular usage. In the 2nd and 3rd centuries Aemilia was frequently named as a district under imperial judges (), generally in combination with Roman Italy#History, Flaminia or Liguria and Tuscia. The district of Province of Ravenna, Ravenna was, as a rule, from the 3rd to the 5th century, not treated as part of Aemilia, the chief town of the latter being Piacenza, Pla ...
