Caesar Cipher
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, would be replaced by , would become , and so on. The method is named after Julius Caesar, who used it in his private correspondence. The encryption step performed by a Caesar cipher is often incorporated as part of more complex schemes, such as the Vigenère cipher, and still has modern application in the ROT13 system. As with all single-alphabet substitution ciphers, the Caesar cipher is easily broken and in modern practice offers essentially no communications security. Example The transformation can be represented by aligning two alphabets; the cipher is the plain alphabet rotated left or right by some number of ...

Caesar Cipher Left Shift Of 3
Gaius Julius Caesar (12 or 13 July 100 BC – 15 March 44 BC) was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in Caesar's civil war, a civil war. He subsequently became Roman dictator, dictator from 49 BC until Assassination of Julius Caesar, his assassination in 44 BC. Caesar played a critical role in Crisis of the Roman Republic, the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Marcus Licinius Crassus, Crassus, and Pompey formed the First Triumvirate, an informal political alliance that dominated Roman politics for several years. Their attempts to amass political power were opposed by many in the Roman Senate, Senate, among them Cato the Younger with the private support of Cicero. Caesar rose to become one of the most powerful politicians in the Roman Republic through a string of military victories in the G ...

Lives Of The Twelve Caesars
''De vita Caesarum'' (Latin; "About the Life of the Caesars"), commonly known as ''The Twelve Caesars'' or ''The Lives of the Twelve Caesars'', is a set of twelve biographies of Julius Caesar and the first 11 emperors of the Roman Empire written by Suetonius, Gaius Suetonius Tranquillus. The subjects consist of: Julius Caesar (d. 44 BC), Augustus, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, Vespasian, Titus, Domitian (d. 96 AD).

YHWH
The TetragrammatonPronounced ; ; also known as the Tetragram. is the four-letter Hebrew-language theonym (transliterated as YHWH or YHVH), the name of God in the Hebrew Bible. The four Hebrew letters, written and read from right to left, are '' yod'', '' he'', '' vav'', and ''he''.The word "tetragrammaton" originates from Greek 'four' + ( ) 'letter' The name may be derived from a verb that means 'to be', 'to exist', 'to cause to become', or 'to come to pass'. While there is no consensus about the structure and etymology of the name, the form ''Yahweh'' (with niqqud: ) is now almost universally accepted among Biblical and Semitic linguistics scholars,The form ''Yahweh'' is also dominant in Christianity, but is not used in Islam or Judaism. though the vocalization ''Jehovah'' continues to have wide usage, especially in Christian traditions. In modernity, Christianity is the only Abrahamic religion in which the Tetragrammaton is freely and openly pronounced. The books of th ...

Hebrew Alphabet
The Hebrew alphabet (, ), known variously by scholars as the Ktav Ashuri, Jewish script, square script and block script, is a unicase, unicameral abjad script used in the writing of the Hebrew language and other Jewish languages, most notably Yiddish, Judaeo-Spanish, Ladino, Judeo-Arabic languages, Judeo-Arabic, and Judeo-Persian. In modern Hebrew, vowels are increasingly introduced. It is also used informally in Israel to write Levantine Arabic, especially among Druze in Israel, Druze. It is an offshoot of the Aramaic alphabet, Imperial Aramaic alphabet, which flourished during the Achaemenid Empire and which itself derives from the Phoenician alphabet. Historically, a different abjad script was used to write Hebrew: the original, old Hebrew script, now known as the Paleo-Hebrew alphabet, has been largely preserved in a variant form as the Samaritan script, Samaritan alphabet, and is still used by the Samaritans. The present ''Jewish script'' or ''square script'', on the cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mezuzah
A ''mezuzah'' ( "doorpost"; plural: ''mezuzot'') is a piece of parchment inscribed with specific Hebrew language, Hebrew verses from the Torah, which Jews affix in a small case to the doorposts of their homes. These verses are the Biblical passages in which the use of a mezuzah is commanded ( and ); they also form part of the Shema Yisrael, Shema prayer. According to Halakha, traditional Jewish law, a ''mezuzah'' must be placed on every Post and lintel, post-and-lintel entrance to a residence, courtyard, or city. Since the time of Meir of Rothenburg (), religious Jews have increasingly also placed ''mezuzot'' on the entrances to non-residential buildings such as synagogues and offices, and on each internal doorway of the home or building, with the exception of bathrooms (where the Names of God, name of God is forbidden) and small closets. The ''klaf'' is prepared by a qualified scribe ("''sofer stam'') who has undergone training, both in studying the relevant religious laws, ...

Atbash
Atbash (; 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 ISO basic Latin alphabet would work like this: Because 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, and second to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebrew Language
Hebrew (; ''ʿÎbrit'') is a Northwest Semitic language within the Afroasiatic language family. A regional dialect of the Canaanite languages, it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the liturgical language of Judaism (since the Second Temple period) and Samaritanism. The language was revived as a spoken language in the 19th century, and is the only successful large-scale example of linguistic revival. It is the only Canaanite language, as well as one of only two Northwest Semitic languages, with the other being Aramaic, still spoken today. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab
Arabs (, , ; , , ) are an ethnic group mainly inhabiting the Arab world in West Asia and North Africa. A significant Arab diaspora is present in various parts of the world. Arabs have been in the Fertile Crescent for thousands of years. In the 9th century BCE, the Assyrians made written references to Arabs as inhabitants of the Levant, Mesopotamia, and Arabia. Throughout the Ancient Near East, Arabs established influential civilizations starting from 3000 BCE onwards, such as Dilmun, Gerrha, and Magan (civilization), Magan, playing a vital role in trade between Mesopotamia, and the History of the Mediterranean region, Mediterranean. Other prominent tribes include Midian, ʿĀd, and Thamud mentioned in the Hebrew Bible, Bible and Quran. Later, in 900 BCE, the Qedarites enjoyed close relations with the nearby Canaan#Canaanites, Canaanite and Aramaeans, Aramaean states, and their territory extended from Lower Egypt to the Southern Levant. From 1200 BCE to 110 BCE, powerful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Kindi
Abū Yūsuf Yaʻqūb ibn ʼIsḥāq aṣ-Ṣabbāḥ al-Kindī (; ; ; ) was an Arab Muslim polymath active as a philosopher, mathematician, physician, and music theorist Music theory is the study of theoretical frameworks for understanding the practices and possibilities of music. '' The Oxford Companion to Music'' describes three interrelated uses of the term "music theory": The first is the " rudiments", that .... Al-Kindi was the first of the Early Islamic philosophy, Islamic peripatetic philosophers, and is hailed as the "father of Arab philosophy". Al-Kindi was born in Kufa and educated in Baghdad. He became a prominent figure in the House of Wisdom, and a number of Abbasid Caliphs appointed him to oversee the translation of Ancient Greece, Greek scientific and philosophical texts into the Arabic language. This contact with "the philosophy of the ancients" (as Hellenistic philosophy was often referred to by Muslim scholars) had a profound effect on him, as he synthes ...

Aulus Gellius
Aulus Gellius (c. 125after 180 AD) was a Roman author and grammarian, who was probably born and certainly brought up in Rome. He was educated in Athens, after which he returned to Rome. He is famous for his ''Attic Nights'', a commonplace book, or compilation of notes on grammar, philosophy, history, antiquarianism, and other subjects, preserving fragments of the works of many authors who might otherwise be unknown today. Name Medieval manuscripts of the ''Noctes Atticae'' commonly gave the author's name in the form of "Agellius", which is used by Priscian; Lactantius, Servius and Saint Augustine had "A. Gellius" instead. Scholars from the Renaissance onwards hotly debated which one of the two transmitted names is correct (the other one being presumably a corruption) before settling on the latter of the two in modern times. Life The only source for the life of Aulus Gellius is the details recorded in his writings. Internal evidence points to Gellius having been born between A ...

The reign of Augustus initiated an Roman imperial cult, imperial cult and an era of regional hegemony, imperial peace (the or ) in which the Roman world was largely free of armed conflict. The Principate system of government was established during his reign and lasted until the Crisis of the Third Century. Octavian was born into an equites, equestrian branch of the plebeian Octavia gens, Octavia.
