Year 179 ( CLXXIX) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Veru (or, less frequently, year 932 ''Ab urbe condita''). The denomination 179 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roman Numerals
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are written with combinations of letters from the Latin alphabet, each letter with a fixed integer value, modern style uses only these seven: The use of Roman numerals continued long after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced by Arabic numerals; however, this process was gradual, and the use of Roman numerals persists in some applications to this day. One place they are often seen is on clock faces. For instance, on the clock of Big Ben (designed in 1852), the hours from 1 to 12 are written as: The notations and can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring representation of "4" as "" on Roman numeral clocks. Other common uses include year numbers on monuments and buildings and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcomanni
The Marcomanni were a Germanic people * * * that established a powerful kingdom north of the Danube, somewhere near modern Bohemia, during the peak of power of the nearby Roman Empire. According to Tacitus and Strabo, they were Suebian. Origin It is believed their name may derive from Proto-Germanic ''*markō'' "border, boundary" (hence the English ''march'' or ''mark'', meaning "frontier, border", as in the Welsh marches and the kingdom of Mercia) and ''*mann-'' (pl. ''*manniz'') "man", ''*Markōmanniz'', which would have been rendered in Latinised form as ''Marcomanni''. The Marcomanni first appear in historical records as confederates of the Suebi of Ariovistus fighting against Julius Caesar in Gaul (now France) after they had crossed the Rhine from what is now southern Germany. The exact position of their lands at the time is not known. The fact that their name existed before the Romans had territory near the Danube or Rhine raises the question of which border they lived ...

Liu Bei
Liu Bei (, ; ; 161 – 10 June 223), courtesy name Xuande (), was a warlord in the late Eastern Han dynasty who founded the state of Shu Han in the Three Kingdoms period and became its first ruler. Although he was a distant relative of the Han imperial family, Liu Bei's father died when he was a child and left his family impoverished. To help his mother, he sold shoes and straw mats. When he reached the age of fifteen, his mother sent him to study under Lu Zhi. In his youth, Liu Bei was known as ambitious and charismatic. He gathered a militia army to fight the Yellow Turbans. Liu Bei fought bravely in many battles and grew famous for his exploits. Later, he participated in the coalition against Dong Zhuo, following this joined his childhood friend Gongsun Zan and fought under him against Yuan Shao.

Pang Tong
Pang Tong () (179–214), courtesy name Shiyuan, was a key adviser to the warlord Liu Bei in the late Eastern Han dynasty of China. In his youth, Pang Tong was disregarded because he was plain looking, however Sima Hui highly esteemed him calling him the "Crown of Scholars in Jing Province". He studied under him along with Zhuge Liang, Xu Shu and Xiang Lang and was given the nickname of "Fledgling Phoenix". Because of his friendly attitude, he worked as an appraiser in Nan Commandery. When reviewing someone, he would prioritize their virtue over their abilities and would encourage them to help others. He briefly served Zhou Yu and befriended Lu Ji, Gu Shao and Quan Cong before joining Liu Bei after the latter became the provincial governor in 210. Under the recommendation of both Lu Su and Zhuge Liang, Liu Bei appointed him to Assistant Officer and promoted him to Military Adviser Generals of the Household. He advised Liu Bei to take over Yi Province accompanied him on his camp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liu Hui
Liu Hui () was a Chinese mathematician who published a commentary in 263 CE on ''Jiu Zhang Suan Shu (The Nine Chapters on the Mathematical Art).'' He was a descendant of the Marquis of Zixiang of the Eastern Han dynasty and lived in the state of Cao Wei during the Three Kingdoms period (220-280 CE) of China. His major contributions as recorded in his commentary on ''The Nine Chapters on the Mathematical Art'' include a proof of the Pythagorean theorem, theorems in solid geometry, an improvement on Archimedes's approximation of , and a systematic method of solving linear equations in several unknowns. In his other work, ''Haidao Suanjing (The Sea Island Mathematical Manual)'', he wrote about geometrical problems and their application to surveying. He probably visited Luoyang, where he measured the sun's shadow. Mathematical work Liu Hui expressed mathematical results in the form of decimal fractions that utilized metrological units (i.e., related units of length with base 10 s ...

Nine Chapters On The Mathematical Art
''The Nine Chapters on the Mathematical Art'' () is a Chinese mathematics book, composed by several generations of scholars from the 10th–2nd century BCE, its latest stage being from the 2nd century CE. This book is one of the earliest surviving mathematical texts from China, the first being '' Suan shu shu'' (202 BCE – 186 BCE) and ''Zhoubi Suanjing'' (compiled throughout the Han until the late 2nd century CE). It lays out an approach to mathematics that centres on finding the most general methods of solving problems, which may be contrasted with the approach common to ancient Greek mathematicians, who tended to deduce propositions from an initial set of axioms. Entries in the book usually take the form of a statement of a problem, followed by the statement of the solution and an explanation of the procedure that led to the solution. These were commented on by Liu Hui in the 3rd century. History Original book The full title of ''The Nine Chapters on the Mathemat ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Han Dynasty
The Han dynasty (, ; ) was an imperial dynasty of China (202 BC – 9 AD, 25–220 AD), established by Liu Bang (Emperor Gao) and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–207 BC) and a warring interregnum known as the ChuHan contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and it has influenced the identity of the Chinese civilization ever since. Modern China's majority ethnic group refers to themselves as the "Han people", the Sinitic language is known as "Han language", and the written Chinese is referred to as "Han characters". The emperor was at the pinnacle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goguryeo
Goguryeo (37 BC–668 AD) ( ) also called Goryeo (), was a Korean kingdom located in the northern and central parts of the Korean Peninsula and the southern and central parts of Northeast China. At its peak of power, Goguryeo controlled most of the Korean peninsula, large parts of Manchuria and parts of eastern Mongolia and Inner Mongolia. Along with Baekje and Silla, Goguryeo was one of the Three Kingdoms of Korea. It was an active participant in the power struggle for control of the Korean peninsula and was also associated with the foreign affairs of neighboring polities in China and Japan. The ''Samguk sagi'', a 12th-century text from Goryeo, indicates that Goguryeo was founded in 37 BC by Jumong (), a prince from Buyeo, who was enthroned as Dongmyeong. Goguryeo was one of the great powers in East Asia, until its defeat by a Silla–Tang alliance in 668 after prolonged exhaustion and internal strife caused by the death of Yeon Gaesomun (). After its fall, its territory w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gogukcheon Of Goguryeo
King Gogukcheon of Goguryeo (died 197, r. 179–197) was the ninth monarch of Goguryeo, one of the Three Kingdoms of Korea. Family *Father: King Sindae (신대왕, 新大王) *Consort: ''Queen'', of the U clan (왕후 우씨, 王后 于氏); daughter of U So (우소, 于素) – No issue. Background and reign Gogukcheon was the second son of Goguryeo's eighth king, Sindae. Though his older brother, Go Balgi (고발기), was originally the crown prince, the court officials supported Gogukcheon, who was made crown prince in 176. However, this record is an error caused by Kim Busik's erroneous quotation of 《Tongdian》, who thought that I-imo was the same person as King Gogukcheon, and the established theory in the Korean history academia is that King Gogukcheon's older brother Gobalgi 奇and King Sansang's older brother Gobalgi 岐are the same person. And it is believed in the Korean history academia that King Gogukcheon was not the second son of King Sindae, but the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edessa, Mesopotamia
Edessa (; grc, Ἔδεσσα, Édessa) was an ancient city (''polis'') in Upper Mesopotamia, founded during the Hellenistic period by King Seleucus I Nicator (), founder of the Seleucid Empire. It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa. The city was situated on the banks of the Daysan River (; ), a tributary of the Khabur, and was defended by Şanlıurfa Castle, the high central citadel. Ancient Edessa is the predecessor of modern Urfa ( tr, Şanlıurfa; ku, Riha; ar, الرُّهَا, ar-Ruhā; hy, Ուռհա, Urha), in the Şanlıurfa Province, Turkey. Modern names of the city are likely derived from Urhay or Orhay ( syc, ܐܘܪܗܝ, ʾŪrhāy / ʾŌrhāy), the site's Syriac name before the re-foundation of the settlement by S ...
