Alexandria In Ariana
The first of many Alexandrias in the Far East of the Macedonian Empire, Alexandria in Ariana was a city in what is now Afghanistan, one of the twenty-plus cities founded or renamed by Alexander the Great. The third largest Afghan city, Herat, is the city's modern name. In 330 BC, the Greek armies of Alexander moved the capital of the satrapy of Aria from Artacoana to the new site. In doing this, he expanded an existing Persian fortress. The location of this town is difficult to determine due to the sparsity of ancient sources. However: * Ptolemy places it near ''lake Arius'' possibly on the west side of lake Zerra at a town called Corra. * Pliny says it was on the Arias River at the location of modern Herat. * Eratosthenes states that Alexandria Arion is 3870 Stadia from Bactra and 6400 Stadia from the Caspian Gates. * Mannert takes the Arius River to be the modern Hari river making the site the village of ''Pilki''.Penny Cyclopaedia of the Society for the Diffusio ...

Lake Zerra
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isidore Of Charax
Isidore of Charax (; grc, Ἰσίδωρος ὁ Χαρακηνός, ''Isídōros o Charakēnós''; la, Isidorus Characenus) was a Greco-Roman geographer of the 1st century BC and 1st century AD, a citizen of the Parthian Empire, about whom nothing is known but his name and that he wrote at least one work. Name Isidore's name has been interpreted by his editor and translator W.H. Schoff to indicate that he was from the city of Charax in Characene on the northern end of the present Persian Gulf. However, the Greek ''charax'' merely means "palisade" and there were several fortified towns that bore the name (''see Charax''). Parthian Stations Isidore's best known work is "The Parthian Stations" ( grc, Σταθμοί Παρθικοί, ''Stathmœ́ Parthicœ́''; la, Mansiones Parthicae), an itinerary of the overland trade route from Antioch to India along the caravan stations maintained by the Arsacid Empire. He seems to have given his distances in schoeni ("ropes") of debated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Society For The Diffusion Of Useful Knowledge
The Society for the Diffusion of Useful Knowledge (SDUK) was founded in London in 1826, mainly at the instigation of Whig MP Henry Brougham, with the object of publishing information to people who were unable to obtain formal teaching or who preferred self-education. It was a largely Whig organisation, and published inexpensive texts intended to adapt scientific and similarly high-minded material for the rapidly-expanding reading public over twenty years until it was disbanded in 1846. Origins Henry Brougham considered that mass education was an essential prerequisite for political reform. In October 1824 he contributed an article on "scientific education of the people" to the Whig ''Edinburgh Review'', in which he argued that popular education would be greatly enhanced by the encouragement of cheap publications to complement the numerous recently founded provincial mechanics' institutes. The following year a version of this article was issued as a pamphlet entitled ''Practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arius River
The Hari River ( or prs, هری رود, translit=Harī Rōd; ps, د هري سیند) or Herat River is a river flowing from the mountains of central Afghanistan to Turkmenistan, where it forms the Tejend oasis and disappears in the Karakum Desert. In its lower course, the river forms a northern part of the border between Afghanistan and Iran, and a southeastern part of the border between Turkmenistan and Iran. In Turkmenistan it is known as the Tejen or Tedzhen river and passes close to the city of Tedzhen. To the Ancient Greeks it was known as the Arius. In Latin, it was known as the Tarius. History Western non Hindu writers claim that Rigveda is said to have recorded the Harirud as the River Sarayu. However, the actual Sarayu is in Uttar Pradesh state of India and arises in Tibetan glaciers near Mt Kailash. It flows through Nepal, before entering India . The river Haroyu is also mentioned in the Avesta. A Buddhist monastery hand-carved in the bluff of the river Harirud exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Konrad Mannert
Konrad Mannert (April 17, 1756 – September 27, 1834) was a Prussian historian and geographer. Mannert was born in Altdorf bei Nürnberg, where he did his studies.

Caspian Gates
The Gates of Alexander were a legendary barrier supposedly built by Alexander the Great in the Caucasus to keep the uncivilized barbarians of the north (typically associated with Gog and Magog in medieval Christian and Islamic writings) from invading the land to the south. The gates were a popular subject in medieval travel literature, starting with the '' Alexander Romance'' in a version from perhaps the 7th century AD. The wall, also known as the Caspian Gates, has been identified with two locations: the Pass of Derbent, Russia, or with the Pass of Dariel, a gorge forming a pass between Russia and Georgia with the Caspian Sea to the east. Tradition also connects it to the Great Wall of Gorgan (Red Snake) on its south-eastern shore. These fortifications were historically part of the defence lines built by the Sassanid Persians, while the Great Wall of Gorgan may have been built by the Parthians. A similar narration about such a wall is mentioned in ''al-Kahf'' ("''The C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stadia (length)
The stadion (plural stadia, grc-gre, ; latinized as stadium), also anglicized as stade, was an ancient Greek unit of length, consisting of 600 Ancient Greek feet (''podes''). Calculations According to Herodotus, one stadium was equal to 600 Greek feet (''podes''). However, the length of the foot varied in different parts of the Greek world, and the length of the stadion has been the subject of argument and hypothesis for hundreds of years. An empirical determination of the length of the stadion was made by Lev Vasilevich Firsov, who compared 81 distances given by Eratosthenes and Strabo with the straight-line distances measured by modern methods, and averaged the results. He obtained a result of about . Various equivalent lengths have been proposed, and some have been named. Among them are: Which measure of the stadion is used can affect the interpretation of ancient texts. For example, the error in the calculation of Earth's circumference by Eratosthenes or Posidoniu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eratosthenes
Eratosthenes of Cyrene (; grc-gre, Ἐρατοσθένης ; – ) was a Greek polymath: a mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. His work is comparable to what is now known as the study of geography, and he introduced some of the terminology still used today. He is best known for being the first person known to calculate the circumference of the Earth, which he did by using the extensive survey results he could access in his role at the Library; his calculation was remarkably accurate. He was also the first to calculate Earth's axial tilt, which has also proved to have remarkable accuracy. He created the first global projection of the world, incorporating parallels and meridians based on the available geographic knowledge of his era. Eratosthenes was the founder of scientific chronology; he used Egyptian and Persian records to estimate the dates of the main ...
