Year 179 ( CLXXIX) was a common year starting on Thursday 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 with a fixed integer value. The modern style uses only these seven: The use of Roman numerals continued long after the Fall of the Western Roman Empire, 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 persisted in various places, including on clock face, 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 the representation of "4" as "" on Roman numeral clocks. Other common uses include year numbers on monuments and buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcomanni
The Marcomanni were a Germanic people who lived close to the border of the Roman Empire, north of the River Danube, and are mentioned in Roman records from approximately 60 BC until about 400 AD. They were one of the most important members of the powerful cluster of allied Suebian peoples in this region, which also included the Hermunduri, Varisti, and Quadi along the Danube, and the Semnones and Langobardi to their north. After a major defeat to the Romans in about 9 BC, the Marcomanni somehow received a new king named Maroboduus, who had grown up in Rome. He subsequently led his people and several others into a region surrounded by forests and mountains in the present day Czech Republic. Before 9 BC the homeland of the Marcomanni is not known, but archaeological evidence suggests that they lived near the central Elbe river and Saale, or possibly to the southwest of this region in Franconia. The Marcomanni were first reported by Julius Caesar among the Germanic peoples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liu Bei
Liu Bei (, ; ; 161 – 10 June 223), courtesy name Xuande (), was a China, Chinese warlord in the late Han dynasty#Eastern Han, Eastern Han dynasty who later became the founding Emperor of China, emperor of Shu Han, one of the Three Kingdoms of China. Despite early failings and lacking both the material resources and social status other warlords of his time commanded, he gathered support among Han loyalists who opposed Cao Cao, the warlord who controlled the Han central government and the figurehead Emperor Xian of Han, Emperor Xian, and led a popular movement to restore the Han dynasty. Liu Bei overcame a number of setbacks to carve out his own realm, which at its peak spanned present-day Sichuan, Chongqing, Guizhou, Hunan, and parts of Hubei, Yunnan, and Gansu. Bolstered by the cultural influence of the 14th-century historical novel ''Romance of the Three Kingdoms'' and its portrayal of Liu Bei as an exemplar of virtuous Confucianism, Confucian rule, Liu Bei is widely revered ...

Pang Tong
Pang Tong () (179–214), courtesy name Shiyuan, was a Chinese politician who served as 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. The hermit scholar Sima Hui, however, held him in high esteem and called him the "Crown of Scholars in Jing Province". Pang Tong studied under Sima Hui along with Zhuge Liang, Xu Shu and Xiang Lang, and he was given the nickname "Fledgling Phoenix". Owing to his friendly attitude, he worked as an appraiser in Nan Commandery. When he reviewed someone, he would prioritise their virtues over their abilities and encourage them to help others. Pang Tong briefly served under Zhou Yu and befriended Lu Ji (Gongji), Lu Ji, Gu Shao and Quan Cong before joining Liu Bei after Liu Bei became the governor of Jing Province in 210. Through the recommendation of Lu Su and Zhuge Liang, Pang Tong was appointed by Liu Bei as an Assistant Officer and subsequently prom ...

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 wit ...

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 1st century CE. This book is one of the earliest surviving mathematical texts from China, the others being the '' 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. The book was later included in the early Tang collection, the '' Ten Computational ...

Han Dynasty
The Han dynasty was an Dynasties of China, imperial dynasty of China (202 BC9 AD, 25–220 AD) established by Liu Bang and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–206 BC) and a warring interregnum known as the Chu–Han 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 the usurping regent Wang Mang, and is thus separated into two periods—the #Western Han (202 BC – 9 AD), Western Han (202 BC9 AD) and the #Eastern Han (25–220 AD), Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a Golden ages of China, golden age in Chinese history, and had a permanent impact on Chinese identity in later periods. The majority ethnic group of modern China refer to themselves as the "Han people" or "Han Chinese". The spoken Chinese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gogukcheon Of Goguryeo
King Gogukcheon ( died 197, r. 179–197) was the ninth monarch of Goguryeo, one of the Three Kingdoms of Korea. According to Samguk sagi, King Gogukcheon's height was recorded as 9 chi. Family *Father: King Sindae () *Consort: ''Queen'', of the U clan (); daughter of U So () – No issue. Background and reign Gogukcheon was the second son of Goguryeo's eighth king, Sindae. Though his older brother, Go Balgi (), 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.
