Sigma (letter)
Sigma (; uppercase Σ, lowercase σ, lowercase in word-final position ς; grc-gre, σίγμα) 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" ...

Uppercase
Letter case is the distinction between the Letter (alphabet), letters that are in larger uppercase or capitals (or more formally ''majuscule'') and smaller lowercase (or more formally ''minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper and lowercase have two parallel sets of letters, with each letter in one set usually having an equivalent in the other set. The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are 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 prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such as the first letter of a Sentence (ling ...

Doric Greek
Doric or Dorian ( grc, Δωρισμός, Dōrismós), also known as West Greek, was a group of Ancient Greek dialects; its varieties are divided into the Doric proper and Northwest Doric subgroups. Doric was spoken in a vast area, that included northern Greece ( Acarnania, Aetolia, Epirus, western and eastern Locris, Phocis, Doris, and possibly ancient Macedonia), most of the Peloponnese (Achaea, Elis, Messenia, Laconia, Argolid, Aegina, Corinth, and Megara), the southern Aegean (Kythira, Milos, Thera, Crete, Karpathos, and Rhodes), as well as the colonies of some of the aforementioned regions, in Cyrene, Magna Graecia, the Black Sea, the Ionian Sea and the Adriatic Sea. It was also spoken in the Greek sanctuaries of Dodona, Delphi, and Olympia, as well as at the four Panhellenic festivals; the Isthmian, Nemean, Pythian, and Olympic Games. By Hellenistic times, under the Achaean League, an Achaean Doric koine appeared, exhibiting many peculiarities common to all Doric d ...

Crescent
A crescent shape (, ) is a symbol or emblem used to represent the lunar phase in the first quarter (the "sickle moon"), or by extension a symbol representing the Moon itself. In Hinduism, Lord Shiva is often shown wearing a crescent moon on his head symbolising that the lord is the master of time and is himself timeless. It is used as the astrological symbol for the Moon, and hence as the alchemical symbol for silver. It was also the emblem of Diana/Artemis, and hence represented virginity. In Christianity Marian veneration, it is associated with the Virgin Mary. From its use as roof finial in Ottoman era mosques, it has also become associated with Islam, and the crescent was introduced as chaplain badge for Muslim chaplains in the US military in 1993.On December 14, 1992, the Army Chief of Chaplains requested that an insignia be created for future Muslim chaplains, and the design (a crescent) was completed January 8, 1993.

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 primar ...

Hellenistic Period
In Classical antiquity, the Hellenistic period covers the time in Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Egypt the following year. The Ancient Greek word ''Hellas'' (, ''Hellás'') was gradually recognized as the name for Greece, from which the word ''Hellenistic'' was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great. After the Macedonian invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout south-west Asia ( Seleucid Empire, Kingdom of Pergamon), north-east Africa ( Ptolemaic Kingdom) and South Asia ( Greco-Bactrian Kingdom, Indo-Greek ...

Metochion Gethsimanis, Jerusalem
A ''metochion'' or ''metochi'' ( gr, μετόχιον, metóchion or gr, μετόχι, metóchi; russian: подворье, podvorie) 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 ca ...

Madaba Jerusalem Mosaic
Madaba ( ar, مادبا; Biblical Hebrew: ''Mēḏəḇāʾ''; grc, Μήδαβα) is the capital city of Madaba Governorate in central Jordan, with a population of about 60,000. It is best known for its Byzantine and Umayyad mosaics, especially a large Byzantine-era mosaic map of the Holy Land. Madaba is located south-west of the capital Amman. History Madaba dates from the Middle Bronze Age. The town of Madaba was once a Moabite border city, mentioned in the Bible in Numbers 21:30 and Joshua 13:9. Control over the city changed back and forth between Israel and Moab, as mentioned in the Mesha Stele. During its rule by the Roman and Byzantine empires from the 2nd to the 7th centuries, the city formed part of the Provincia Arabia set up by the Roman Emperor Trajan to replace the Nabataean kingdom of Petra. The first evidence for a Christian community in the city, with its own bishop, is found in the Acts of the Council of Chalcedon in 451, where Constantine, Metropolita ...

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 1900 BCE, with the diversification into a southern and a northern group beginning by approximately 1700 BCE. Origins Proto-Greek emerged from the diversification of the Proto-Indo-European language (PIE), the last phase of which gave rise to the later language families occurred BCE. Pre-Proto-Greek, the Indo-European dialect from which Proto-Greek originated, emerged BCE in an area which bordered pre- Proto-Indo-Iranian to the east and pre-Proto-Armenian and pre-Proto- Phrygian to the west, ...

Xi (letter)
Xi is the 14th letter of the Greek alphabet (uppercase Ξ, lowercase ξ; el, ξι), representing the voiceless consonant cluster . It is pronounced in Modern Greek, and generally or in English. 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 ...

Samekh
Samekh (Phoenician ''sāmek'' ; Hebrew ''samekh'' , Syriac ''semkaṯ'') is the fifteenth letter of the Semitic abjads, including the Hebrew alphabet. Samekh represents a voiceless alveolar fricative . Unlike most Semitic consonants, the pronunciation of remains constant between vowels and before voiced consonants. In the Hebrew language, the samekh generally shares a similar pronunciation as the left-dotted shin. The numerical value of samekh is 60. History The Phoenician letter may continue a glyph from the Middle Bronze Age alphabets, either based on a hieroglyph for a tent peg or support, possibly the ''djed'' "pillar" hieroglyph (c.f. Hebrew root סמך s-m-kh 'support', סֶמֶךְ semekh 'support, rest', סוֹמֵךְ somekh 'support peg, post', סוֹמְכָה somkha 'armrest', סָמוֹכָה smokha 'stake, support', indirectly '' s'mikhah'' ; Aramaic סַמְכָא samkha 'socket, base', סְמַךְ smakh 'support, help'; Syriac ܣܡܟܐ semkha 'support') ...
