Earth Symbol (bold)
A variety of symbols or iconographic conventions are used to represent Earth, whether in the sense of planet Earth, or the inhabited world, or as a classical element. A circle representing the round world, with the rivers of Garden of Eden separating the four corners of the world, or rotated 45° to suggest the four continents, remains a common pictographic convention to express the notion of "worldwide". The current astronomical symbols for the planet are a circle with an intersecting cross, 20px, 🜨, alt=An equilateral cross enclosed in a circle, and a ''globus cruciger'', 20px, ♁. Although the International Astronomical Union (IAU) now discourages the use of planetary symbols, this is an exception, being used in abbreviations such as ''M''🜨 or ''M''♁ for Earth mass. History The earliest type of symbols are allegories, personifications or deifications, mostly in the form of an Earth goddess (in the case of Egyptian mythology a god, Geb).

Globus Cruciger
The for, la, globus cruciger, cross-bearing orb, also known as ''stavroforos sphaira'' () or "the orb and cross", is an Sphere, orb surmounted by a Christian cross, cross. It has been a Christian Church, Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with a sceptre as royal regalia. The cross laid over the globus represents Christ's dominion over the world, literally held in the hand of a worthy earthly ruler. In the iconography of Art of Europe, Western art, when Christ himself holds the globe, he is called ''Salvator Mundi'' (Latin for 'Saviour of the World'). For instance, the 16th-century Infant Jesus of Prague statue holds a ''globus cruciger'' in this manner.

Earth Mass
An Earth mass (denoted as ''M''🜨, ''M''♁ or ''M''E, where 🜨 and ♁ are the astronomical symbols for Earth), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is , with a relative uncertainty of 10−4.The cited value is the recommended value published by the International Astronomical Union in 2009 (se2016 "Selected Astronomical Constants" in ). It is equivalent to an average density of . Using the nearest metric prefix, the Earth mass is approximately six ronnagrams, or 6.0 Rg. The Earth mass is a standard unit of mass in astronomy that is used to indicate the masses of other planets, including rocky terrestrial planets and exoplanets. One Solar mass is close to Earth masses. The Earth mass excludes the mass of the Moon. The mass of the Moon is about 1.2% of that of the Earth, so that the mass of the Earth–Moon system is close to . Most of the mass is accounted for by iron and oxygen (c. 32% each), m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I Ching
The ''I Ching'' or ''Yijing'' ( ), usually translated ''Book of Changes'' or ''Classic of Changes'', is an ancient Chinese divination text that is among the oldest of the Chinese classics. The ''I Ching'' was originally a divination manual in the Western Zhou period (1000–750 BC). Over the course of the Warring States period, Warring States and early imperial periods (500–200 BC), it transformed into a Religious cosmology, cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classics in the 2nd century BC, the ''I Ching'' was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought. As a divination text, the ''I Ching'' is used for a Chinese form of cleromancy known as I Ching divination, ''I Ching'' div ...

Bagua
The ''bagua'' ( zh, c=八卦, p=bāguà, l=eight trigrams) is a set of symbols from China intended to illustrate the nature of reality as being composed of mutually opposing forces reinforcing one another. ''Bagua'' is a group of trigrams—composed of three lines, each either "broken" or "unbroken", which represent yin and yang, respectively. Each line having two possible states allows for a total of 23 = 8 trigrams, whose early enumeration and characterization in China has had an effect on the history of Chinese philosophy and cosmology. The trigrams are related to the divination practice as described within the ''I Ching'' and practiced as part of the Shang and Zhou state religion, as well as with the concepts of '' taiji'' and the five elements within traditional Chinese metaphysics. The trigrams have correspondences in astronomy, divination, meditation, astrology, geography, geomancy (feng shui), anatomy, decorative arts, the family, martial arts (particularly tai chi an ...

Earth (wuxing)
In Chinese philosophy, earth or soil () is one of the five concepts that conform the ''wuxing''. Earth is the Qi balance of both yin and yang in the Wuxing philosophy, as well as the changing or central point of physical matter or a subject. Its motion is centralising, and its energy is stabilizing and conserving. Earth is associated with the colour yellow or ochre and the planet Saturn (not to be confused with planet Earth), and it lies at the centre of the four directions of the compass in Chinese cosmology. It is associated with late summer and the turn of each of the four seasons, as Earth is prone to being over burdened. Its climate is that of dampness causing the mind to be clouded through a deficiency of yang qi. In traditional Chinese medicine, earth governs the yin, Zang organ the spleen, and the yang, Fu organ stomach, mouth and muscles. Its Primal Spirit is the Yi, and emotion of happiness and is represented by the Yellow Dragon or Qilin, color yellow and Golden ( S ...

Chinese Characters
Chinese characters are logographs used Written Chinese, to write the Chinese languages and others from regions historically influenced by Chinese culture. Of the four independently invented writing systems accepted by scholars, they represent the only one that has remained in continuous use. Over a documented history spanning more than three millennia, the function, style, and means of writing characters have changed greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes, the units of meaning in a language. Writing all of the frequently used vocabulary in a language requires roughly 2000–3000 characters; , nearly have been identified and included in ''The Unicode Standard''. Characters are created according to several principles, where aspects of shape and pronunciation may be used to indicate the character's meaning. The first attested characters are oracle bone inscriptions made during the 13th century&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cuneiform
Cuneiform is a Logogram, logo-Syllabary, syllabic writing system that was used to write several languages of the Ancient Near East. The script was in active use from the early Bronze Age until the beginning of the Common Era. Cuneiform scripts are marked by and named for the characteristic wedge-shaped impressions (Latin: ) which form their Grapheme, signs. Cuneiform is the History of writing#Inventions of writing, earliest known writing system and was originally developed to write the Sumerian language of southern Mesopotamia (modern Iraq). Over the course of its history, cuneiform was adapted to write a number of languages in addition to Sumerian. Akkadian language, Akkadian texts are attested from the 24th century BC onward and make up the bulk of the cuneiform record.

Egyptian Hieroglyph
Ancient Egyptian hieroglyphs ( ) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 distinct characters.In total, there were about 1,000 graphemes in use during the Old Kingdom period; this number decreased to 750–850 during the Middle Kingdom, but rose instead to around 5,000 signs during the Ptolemaic period. Antonio Loprieno, ''Ancient Egyptian: A Linguistic Introduction'' (Cambridge: Cambridge UP, 1995), p. 12. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic ...

Hellenistic Period
In classical antiquity, the Hellenistic period covers the time in Greek history after Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII in 30 BC, which was followed by the ascendancy of the Roman Empire, as signified by the Battle of Actium in 31 BC and the Roman conquest of Ptolemaic Egypt the following year, which eliminated the last major Hellenistic kingdom. Its name stems from the Ancient Greek word ''Hellas'' (, ''Hellás''), which was gradually recognized as the name for Greece, from which the modern historiographical term ''Hellenistic'' was derived. The term "Hellenistic" is to be distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all the ancient territories of the period that had come under significant Greek influence, particularly the Hellenized Middle East, after the conquests of Alexander the Great. After the Macedonian conquest of the Achaemenid Empire in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spherical Earth
Spherical Earth or Earth's curvature refers to the approximation of the figure of the Earth as a sphere. The earliest documented mention of the concept dates from around the 5th century BC, when it appears in the writings of Ancient Greek philosophy, Greek philosophers. In the 3rd century BC, History of geodesy#Hellenic world, Hellenistic astronomy established the figure of the Earth, roughly spherical shape of Earth as a physical fact and calculated the Earth's circumference. This knowledge was gradually adopted throughout the Old World during late antiquity, Late Antiquity and the Middle Ages, displacing earlier beliefs in a flat earth.Adoption by China via European science: and A practical demonstration of Earth's sphericity was achieved by Ferdinand Magellan and Juan Sebastián Elcano's circumnavigation (1519–1522). The realization that the figure of the Earth is more accurately described as an Earth ellipsoid, ellipsoid dates to the 17th century, as described by Isa ...
