Hyginus Gromaticus
Hyginus Gromaticus (Gromaticus from '' groma'', a surveying device) was a Latin writer on land-surveying, who flourished in the reign of Trajan (AD 98–117). Fragments of a work on boundaries attributed to him are found in ''Corpus Agrimensorum Romanorum'', a collection of works on land surveying compiled in Late Antiquity. The 'surname' Gromaticus ("surveyor") is a false attribution. Origin of the epithet "Gromaticus" Hyginus Gromaticus (''Gromaticus'', meaning "surveyor," derives from groma, a measuring instrument used by ancient Roman surveyors) is known only from his work ''De Constitutione Limitum'' (On the Establishment of Boundaries) in the ''Corpus Agrimensorum Romanorum'', a collection of works on land surveying compiled in Late Antiquity. He probably lived between the end of the first century AD and the reign of the Emperor Trajan. His epithet "Gromaticus" is a false reading which goes back to the oldest manuscript, the ''Codex Arcerianus'', in which the subscript ...

Groma Surveying
The ''groma'' or ''gruma'' was a Roman surveying instrument. It comprised a vertical staff with horizontal cross-pieces mounted at right angles on a bracket. Each cross piece had a plumb line hanging vertically at each end. It was used to survey straight lines and right angles, thence squares or rectangles. They were stabilized on the high ground, and pointed in the direction it was going to be used. The helper would step back 100 steps and place a pole. The surveyor would tell him where to move the pole and the helper would set it down. The same name was given to: * the center of any new military camp, i.e. the point from which was traced the regular grid by using the ''groma'' instrument * the center of a new town, from which the gromatici (surveyors) began to lay out cardo and decumanus grid, with a plough and a pair of oxen The groma surveying instrument may have originated in Mesopotamia or Greece before the 4th century BC. Subsequently, it was brought to Rome by the Etrusc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnomon
A gnomon (; ) is the part of a sundial that casts a shadow. The term is used for a variety of purposes in mathematics and other fields. History A painted stick dating from 2300 BC that was excavated at the astronomical site of Taosi is the oldest gnomon known in China. The gnomon was widely used in ancient China from the second century BC onward in order to determine the changes in seasons, orientation, and geographical latitude. The ancient Chinese used shadow measurements for creating calendars that are mentioned in several ancient texts. According to the collection of Zhou Chinese poetic anthologies ''Classic of Poetry'', one of the distant ancestors of King Wen of the Zhou dynasty used to measure gnomon shadow lengths to determine the orientation around the 14th century BC. The ancient Greek philosopher Anaximander (610–546 BC) is credited with introducing this Babylonian instrument to the Ancient Greeks. The ancient Greek mathematician and astronomer Oenopides used the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Age Latin Writers
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Roman Writers
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages varies between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was already exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world population stood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Munitionibus Castrorum
''De Munitionibus Castrorum'' ("Concerning the fortifications of a military camp") is a work by an unknown author. Due to this work formerly being attributed to Hyginus Gromaticus, its author is often called "Pseudo-Hyginus". This work is the most detailed surviving description of a Roman military camp (Latin: ''castra'') and dates most probably from the late 1st to early 2nd century AD. The author and the time of creation of the work Very little is known about the author of ''De munitionibus castrorum''. According to the text, his work was intended to be a useful manual about how to properly lay out a military camp, specially written for a high-ranked officer: :''"novitatem metationis ad magnitudinem tuam primus adferam, quae tibi spero placebit, si primum cottidianam metationem tractabis"'' He also suggests that he was a beginner author and used other authors' works relevant to the theme: :''"In quantum potui, domine frater, pro tirocinio meo, in brevi omnes auctores sum perse ...

Castra
In the Roman Republic and the Roman Empire, the Latin word ''castrum'', plural ''castra'', was a military-related term. In Latin usage, the singular form ''castrum'' meant 'fort', while the plural form ''castra'' meant 'camp'. The singular and plural forms could refer in Latin to either a building or plot of land, used as a fortified military base.. Included is a discussion about the typologies of Roman fortifications. In English usage, ''castrum'' commonly translates to "Roman fort", "Roman camp" and "Roman fortress". However, scholastic convention tends to translate ''castrum'' as "fort", "camp", "marching camp" or "fortress". Romans used the term ''castrum'' for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments, and "marching" forts. The diminutive form ''castellum'' was used for fortlets, typically occupied by a detachment of a cohort or a '' centuria''. For a list of known castr ...

Grid Plan
In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. Two inherent characteristics of the grid plan, frequent intersections and orthogonal geometry, facilitate movement. The geometry helps with orientation and wayfinding and its frequent intersections with the choice and directness of route to desired destinations. In ancient Rome, the grid plan method of land measurement was called centuriation. The grid plan dates from antiquity and originated in multiple cultures; some of the earliest planned cities were built using grid plans in Indian subcontinent. History Ancient grid plans By 2600 BC, Mohenjo-daro and Harappa, major cities of the Indus Valley civilization, were built with blocks divided by a grid of straight streets, running north–south and east–west. Each block was subdivided by small lanes. The cities and monasteries of Sirkap, Taxila and Thimi (in the Ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
