Sigma Summation Notation
Sigma ( ; uppercase Σ, lowercase σ, lowercase in word-final position ς; ) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In ' (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end. The Latin letter S derives from sigma while the Cyrillic letter Es derives from a lunate form of this letter. History The shape (Σς) and alphabetic position of sigma is derived from the Phoenician letter ( ''shin''). Sigma's original name may have been ''san'', but due to the complicated early history of the Greek epichoric alphabets, ''san'' came to be identified as a separate letter in the Greek alphabet, represented as Ϻ. Herodotus reports that "san" was the name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uppercase
Letter case is the distinction between the letters that are in larger uppercase or capitals (more formally ''#Majuscule, majuscule'') and smaller lowercase (more formally ''#Minuscule, minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper- and lowercase have two parallel sets of letters: each in the majuscule set has a counterpart in the minuscule set. Some counterpart letters have the same shape, and differ only in size (e.g. ), but for others the shapes are different (e.g., ). The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are typically treated identically when sorting in alphabetical order. Letter case is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often denoted by the grammar of a language or by the conventions of a particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herodotus
Herodotus (; BC) was a Greek historian and geographer from the Greek city of Halicarnassus (now Bodrum, Turkey), under Persian control in the 5th century BC, and a later citizen of Thurii in modern Calabria, Italy. He wrote the '' Histories'', a detailed account of the Greco-Persian Wars, among other subjects such as the rise of the Achaemenid dynasty of Cyrus. He has been described as " The Father of History", a title conferred on him by the ancient Roman orator Cicero, and the " Father of Lies" by others. The ''Histories'' primarily cover the lives of prominent kings and famous battles such as Marathon, Thermopylae, Artemisium, Salamis, Plataea, and Mycale. His work deviates from the main topics to provide a cultural, ethnographical, geographical, and historiographical background that forms an essential part of the narrative and provides readers with a wellspring of additional information. Herodotus was criticized in his times for his inclusion of "legends an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epigraphic
Epigraphy () is the study of inscriptions, or epigraphs, as writing; it is the science of identifying graphemes, clarifying their meanings, classifying their uses according to dates and cultural contexts, and drawing conclusions about the writing and the writers. Specifically excluded from epigraphy are the historical significance of an epigraph as a document and the artistic value of a literary composition. A person using the methods of epigraphy is called an ''epigrapher'' or ''epigraphist''. For example, the Behistun inscription is an official document of the Achaemenid Empire engraved on native rock at a location in Iran. Epigraphists are responsible for reconstructing, translating, and dating the trilingual inscription and finding any relevant circumstances. It is the work of historians, however, to determine and interpret the events recorded by the inscription as document. Often, epigraphy and history are competences practised by the same person. Epigraphy is a primary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hellenistic Period
In classical antiquity, the Hellenistic period covers the time in Greek history after Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII in 30 BC, which was followed by the ascendancy of the Roman Empire, as signified by the Battle of Actium in 31 BC and the Roman conquest of Ptolemaic Egypt the following year, which eliminated the last major Hellenistic kingdom. Its name stems from the Ancient Greek word ''Hellas'' (, ''Hellás''), which was gradually recognized as the name for Greece, from which the modern historiographical term ''Hellenistic'' was derived. The term "Hellenistic" is to be distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all the ancient territories of the period that had come under significant Greek influence, particularly the Hellenized Middle East, after the conquests of Alexander the Great. After the Macedonian conquest of the Achaemenid Empire in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metochion Gethsimanis, Jerusalem
A ''metochion'' or ''metochi'' ( or ; ) is an ecclesiastical embassy church within Eastern Orthodox tradition. It is usually from one autocephalous or autonomous church to another. The term is also used to refer to a parish representation (or dependency) of a monastery or a primate. Ecclesiastical embassy church In the former case, the local territorial church grants a plot of land or a church building for the use of the foreign church being represented, and the location is then considered to belong canonically to the foreign church. Services held there are often in the language appropriate to the church being represented, and the congregation is often made up of immigrants or visitors from the nation associated with that church. Typically, a ''metochion'' presence on the territory of an autocephalous church is limited to only a few parishes at most. Dependency of a monastery In the case of a monastic ''metochion'', such a parish church is a dependency of a particular monastic ...

Proto-Greek Language
The Proto-Greek language (also known as Proto-Hellenic) is the Indo-European language which was the last common ancestor of all varieties of Greek, including Mycenaean Greek, the subsequent ancient Greek dialects (i.e., Attic, Ionic, Aeolic, Doric, Arcadocypriot, and ancient Macedonian—either a dialect or a closely related Hellenic language) and, ultimately, Koine, Byzantine and Modern Greek (along with its variants). Proto-Greek speakers entered Greece sometime between 2200 and 1900BC, with the diversification into a southern and a northern group beginning by approximately 1700BC. Origins Proto-Greek emerged from the diversification of the late Proto-Indo-European language (PIE); a process whose last phase gave rise to the later language families and occurred .. Pre-Proto-Greek, the Indo-European dialect from which Proto-Greek originated, emerged , in an area which bordered pre- Proto-Indo-Iranian to the east and pre- Proto-Armenian and pre-Proto- Phrygian to ...

Xi (letter)
Xi ( or ; uppercase Ξ, lowercase ξ; ) is the fourteenth letter of the Greek alphabet, representing the voiceless consonant cluster . Its name is pronounced in Modern Greek. In the system of Greek numerals, it has a value of 60. Xi was derived from the Phoenician letter samekh . Xi is distinct from the letter chi, which gave its form to the Latin letter X. Greek Both in classical Ancient Greek and in Modern Greek, the letter Ξ represents the consonant cluster /ks/. In some archaic local variants of the Greek alphabet, this letter was missing. Instead, especially in the dialects of most of the Greek mainland and Euboea, the cluster /ks/ was represented by Χ (which in classical Greek is chi, used for ). Because this variant of the Greek alphabet was used in Magna Graecia (the Greek colonies in Sicily and the southern part of the Italian peninsula), the Latin alphabet borrowed Χ rather than Ξ as the Latin letter that represented the /ks/ cluster that was also ...

Histories (Herodotus)
The ''Histories'' (, ''Historíai''; also known as ''The History'') of Herodotus is considered the founding work of history in Western literature. Although not a fully impartial record, it remains one of the West's most important sources regarding these affairs. Moreover, it established the genre and study of history in the Western world (despite the existence of historical records and chronicles beforehand). ''The'' ''Histories'' also stands as one of the earliest accounts of the rise of the Achaemenid Empire, Persian Empire, as well as the events and causes of the Greco-Persian Wars between the Persian Empire and the Polis, Greek city-states in the 5th century BC. Herodotus portrays the conflict as one between the forces of slavery (the Persians) on the one hand, and freedom (the Athenians and the confederacy of Greek city-states which united against the invaders) on the other. ''The Histories'' was at some point divided into the nine scroll, books that appear in modern editions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
