Alphabetisation
Alphabetical order is a system whereby character strings are placed in order based on the position of the characters in the conventional ordering of an alphabet. It is one of the methods of collation. In mathematics, a lexicographical order is the generalization of the alphabetical order to other data types, such as sequences of numbers or other ordered mathematical objects. When applied to strings or sequences that may contain digits, numbers or more elaborate types of elements, in addition to alphabetical characters, the alphabetical order is generally called a lexicographical order. To determine which of two strings of characters comes first when arranging in alphabetical order, their first letters are compared. If they differ, then the string whose first letter comes earlier in the alphabet comes before the other string. If the first letters are the same, then the second letters are compared, and so on. If a position is reached where one string has no more letters to compare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Character String
In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation). A string is generally considered as a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. ''String'' may also denote more general arrays or other sequence (or list) data types and structures. Depending on the programming language and precise data type used, a variable declared to be a string may either cause storage in memory to be statically allocated for a predetermined maximum length or employ dynamic allocation to allow it to hold a variable number of elements. When a string appears literally in source code, it is known as a string literal or an anonymous string. In formal languages, which are used in mathematical l ...

Atbash
Atbash ( he, אתבש; also transliterated Atbaš) is a monoalphabetic substitution cipher originally used to encrypt the Hebrew alphabet. It can be modified for use with any known writing system with a standard collating order. Encryption The Atbash cipher is a particular type of monoalphabetic cipher formed by taking the alphabet (or abjad, syllabary, etc.) and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example, the Latin alphabet would work like this: Due to the fact that there is only one way to perform this, the Atbash cipher provides no communications security, as it lacks any sort of key. If multiple collating orders are available, which one was used in encryption can be used as a key, but this does not provide significantly more security, considering that only a few letters can give away which one was used. History The name derives from the first, last, second, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpocration
__NOTOC__ Valerius Harpocration ( grc-gre, Οὐαλέριος or , ''gen''. Ἁρποκρατίωνος) was a Greek grammarian of Alexandria, probably working in the 2nd century AD. He is possibly the Harpocration mentioned by Julius Capitolinus (''Life of Verus'', 2) as the Greek tutor of Lucius Verus (2nd century AD); some authorities place him much later, on the ground that he borrowed from Athenaeus. Harpocration's ''Lexicon of the Ten Orators'' (Περὶ τῶν Λέξεων τῶν Δέκα Ῥητόρων, or briefly Λεξικὸν τῶν Δέκα Ῥητόρων), which has come down to us in an incomplete form, contains, in more or less alphabetical order, notes on well-known events and persons mentioned by the orators, and explanations of legal and commercial expressions. As nearly all the lexicons to the Greek orators have been lost, Harpocration's work is especially valuable. Amongst his authorities were the writers of Atthides (histories of Attica), the grammari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Verborum Significatu
''De verborum significatione libri XX'' ('Twenty Books on the Meaning of Words'), also known as the ''Lexicon of Festus'', is an epitome compiled, edited, and annotated by Sextus Pompeius Festus from the encyclopedic works of Verrius Flaccus. Festus' epitome is typically dated to the 2nd century, but the work only survives in an incomplete 11th-century manuscript and copies of its own separate epitome. Background Verrius Flaccus was a prominent Roman grammarian known for his writings on the Latin language and for tutoring the grandsons of Caesar Augustus during his reign. He is best known for ''De verborum significatu'', the name which Festus later adopted for his epitome, the first major alphabetical Latin dictionary. The 40-volume lexicon is regarded as among the most important such works of classical antiquity, though all but a few fragments of the original have been lost, perhaps in part due to its impractical size. Sextus Pompeius Festus, also a grammarian, likely flourish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verrius Flaccus
Marcus Verrius Flaccus (c. 55 BCAD 20) was a Ancient Rome, Roman grammarian and teacher who flourished under Augustus Caesar, Augustus and Tiberius. Life He was a freedman, and his manumitter has been identified with Verrius Flaccus, an authority on pontifical law; but for chronological reasons the name of Veranius Flaccus, a writer on augury, has been suggested (Teuffel-Schwabe, ''Hist. of Roman Lit.'' 199, 4). He gained such a reputation by his methods of instruction that he was summoned to court to bring up Gaius Caesar, Gaius and Lucius Caesar, Lucius, the grandsons of Augustus. He removed there with his whole school, and his salary was greatly increased on the condition that he took no fresh pupils. He died at an advanced age during the reign of Tiberius (Suetonius' minor works, Suetonius, ''De Grammaticis'', 17), and a statue in his honour was erected at Praeneste, in a marble recess, with inscriptions from his ''Fasti Praenestini''.

Epitome
An epitome (; gr, ἐπιτομή, from ἐπιτέμνειν ''epitemnein'' meaning "to cut short") is a summary or miniature form, or an instance that represents a larger reality, also used as a synonym for embodiment. Epitomacy represents "to the degree of." An abridgment differs from an epitome in that an abridgment is made of selected quotations of a larger work; no new writing is composed, as opposed to the epitome, which is an original summation of a work, at least in part. Many documents from the Ancient Greek and Roman worlds survive now only "in epitome," referring to the practice of some later authors (epitomators) who wrote distilled versions of larger works now lost. Some writers attempted to convey the stance and spirit of the original, while others added further details or anecdotes regarding the general subject. As with all secondary historical sources, a different bias not present in the original may creep in. Documents surviving in epitome differ from those su ...

Sextus Pompeius Festus
Sextus Pompeius Festus, usually known simply as Festus, was a Roman grammarian who probably flourished in the later 2nd century AD, perhaps at Narbo (Narbonne) in Gaul. Work He made a 20-volume epitome of Verrius Flaccus's voluminous and encyclopedic treatise ''De verborum significatione''. Flaccus had been a celebrated grammarian who flourished in the reign of Augustus. Festus gives the etymology as well as the meaning of many words, and his work throws considerable light on the language, mythology and antiquities of ancient Rome. He made a few alterations, and inserted some critical remarks of his own. He also omitted such ancient Latin words as had long been obsolete; these he apparently discussed in a separate work now lost, entitled ''Priscorum verborum cum exemplis''. Even incomplete, Festus' lexicon reflects at second hand the enormous intellectual effort that had been made in the Augustan Age to put together information on the traditions of the Roman world, which was alrea ...

Varro
Marcus Terentius Varro (; 116–27 BC) was a Roman polymath and a prolific author. He is regarded as ancient Rome's greatest scholar, and was described by Petrarch as "the third great light of Rome" (after Vergil and Cicero). He is sometimes called Varro Reatinus to distinguish him from his younger contemporary Varro Atacinus. Biography Varro was born in or near Reate (now Rieti) to a family thought to be of equestrian rank, and always remained close to his roots in the area, owning a large farm in the Reatine plain, reported as near Lago di Ripasottile, until his old age. He supported Pompey, reaching the office of praetor, after having been tribune of the people, ''quaestor'' and ''curule aedile''. It is probable that Varro was discontented with the course on which Pompey entered when the First Triumvirate was formed, and he may thus have lost his chance of rising to the consulate. He actually ridiculed the coalition in a work entitled the ''Three-Headed Monster'' ( in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinakes
The ''Pinakes'' ( grc, Πίνακες "tables", plural of ) is a lost bibliographic work composed by Callimachus (310/305–240 BCE) that is popularly considered to be the first library catalog in the West; its contents were based upon the holdings of the Library of Alexandria during Callimachus' tenure there during the third century BCE. History The Library of Alexandria had been founded by Ptolemy I Soter about 306 BCE. The first recorded librarian was Zenodotus of Ephesus. During Zenodotus' tenure, Callimachus, who was never the head librarian, compiled many catalogues/lists, each called ''Pinakes''. His most famous one listed authors and their works; thus he became the first known bibliographer and the scholar who organized the library by authors and subjects about 245 BCE. His work was 120 volumes long. Apollonius of Rhodes was the successor to Zenodotus. Eratosthenes of Cyrene succeeded Apollonius in 235 BCE and compiled his ''tetagmenos epi teis megaleis bibliothekeis' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Catalog
A library catalog (or library catalogue in British English) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A catalog for a group of libraries is also called a union catalog. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library. The card catalog was a familiar sight to library users for generations, but it has been effectively replaced by the online public access catalog (OPAC). Some still refer to the online catalog as a "card catalog". Some libraries with OPAC access still have card catalogs on site, but these are now strictly a secondary resource and are seldom ...

Callimachus
Callimachus (; ) was an ancient Greek poet, scholar and librarian who was active in Alexandria during the 3rd century BC. A representative of Ancient Greek literature of the Hellenistic period, he wrote over 800 literary works in a wide variety of genres, most of which did not survive. He espoused an aesthetic philosophy, known as Callimacheanism, which exerted a strong influence on the poets of the Roman Empire and, through them, on all subsequent Western literature. Born into a prominent family in the Greek city of Cyrene in modern-day Libya, he was educated in Alexandria, the capital of the Ptolemaic kings of Egypt. After working as a schoolteacher in the city, he came under the patronage of King Ptolemy II Philadelphus and was employed at the Library of Alexandria where he compiled the ''Pinakes'', a comprehensive catalogue of all Greek literature. He is believed to have lived into the reign of Ptolemy III Euergetes. Although Callimachus wrote prolifically in prose and p ...

Great Library Of Alexandria
The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The Library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts.Murray, S. A., (2009). The library: An illustrated history. New York: Skyhorse Publishing, p.17 The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the Library, but the Library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The Library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many such scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height. Alexandria came to be regarded ...
