Pyramid Of The Sun
The Pyramid of the Sun is the largest building in Teotihuacan, and one of the largest in Mesoamerica. It is believed to have been constructed about 200 AD. Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city. History The name ''Pyramid of the Sun'' comes from the Aztecs, who visited the city of Teotihuacan centuries after it was abandoned; the name given to the pyramid by the Teotihuacanos is unknown. It was constructed in two phases. The first construction stage, around 200 CE, brought the pyramid to nearly the size it is today. The second round of construction resulted in its completed size of 225 meters (738 feet) across and 75 meters (246 feet) high, making it the third-largest pyramid in the world, though still just over half the height of the Great Pyramid of Giza (146 metres). The second phase also saw the construction o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teotihuacán Municipality
Teotihuacán is a municipalities of Mexico, municipality located in the State of Mexico. The municipal seat is the town of Teotihuacán de Arista. It is in the northeast of the Valley of Mexico, 45 km northeast of Mexico City and 119 km from the state capital of Toluca. Teotihuacan takes its name from Teotihuacan, the ancient city and World Heritage Site that is located next to the municipal seat. "Teotihuacan" is from Nahuatl and means "place of the gods." In Nahua peoples, Nahua mythology the Sun and the Moon were created here. The seal of the municipality features the Pyramid of the Sun from the archeological site, which represents the four cardinal directions. The building is tied to a character that represents water which is linked to an arm that is joined to the head of an indigenous person who is seated and speaking. This person represents a god. Much of the history of the area has been tied to the ancient city, most recently involves controversy connected with comm ...

Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures Completed In The 2nd Century
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Geographic (magazine)
''National Geographic'' (formerly the ''National Geographic Magazine'', sometimes branded as NAT GEO) is a popular American monthly magazine published by National Geographic Partners. Known for its photojournalism, it is one of the most widely read magazines of all time. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well-known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Since 2019, controlling interest has been held by The Walt Disney Company. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a thick squa ...

List Of Mesoamerican Pyramids
This is a list of Mesoamerican pyramids or ceremonial structures. In most cases they are not true pyramids. There are hundreds of these done in many different styles throughout Mexico and Central America. These were made by several pre-Columbian cultures including the Olmecs, Maya, Toltecs, and Aztecs. In most cases they were made by city states that created many structures in the same style. The style for each city state is usually different. These are usually made out of stone and mortar but some of the earliest may have been made out of clay.

British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is among the largest and most comprehensive in existence. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections. The British Museum was the first public national museum to cover all fields of knowledge. The museum was established in 1753, largely b ...

Teotihuacan Ocelot
The Teotihuacan Ocelot or ''Teotihuacán Ocelot'' is the name of an alabaster sculpture of a feline found at the ancient Mesoamerican site of Teotihuacan, central Mexico. Discovered in the late nineteenth century, it was purchased by the British Museum in 1926. Description This unique sculpture is an offering vessel in the form of a recumbent ocelot. Carved from a single piece of prestigious alabaster, the figure reflects the geometric style and pattern of contemporary funerary masks and architecture from Teotihuacan. The eyes would have once been inlaid with shells or precious stones and the depression on the feline's back would have held the temple offering - some have conjectured that this may have included human hearts removed for ritual sacrifices. ...

Temple Of The Feathered Serpent, Teotihuacan
The Temple of the Feathered Serpent is the third largest pyramid at Teotihuacan, a Pre-Columbian Mexico, pre-Columbian site in central Mexico (the term ''Teotihuacan'', or ''Teotihuacano'', is also used for the whole civilization and cultural complex associated with the site). This structure is notable partly due to the discovery in the 1980s of more than a hundred possibly sacrificial victims found buried beneath the structure. The burials, like the structure, are dated to between 150 and 200 CE. The pyramid takes its name from representations of the Mesoamerican "feathered serpent" deity which covered its sides. These are some of the earliest-known representations of the feathered serpent, often identified with the much-later Aztec god Quetzalcoatl. "Temple of the Feathered Serpent" is the modern-day name for the structure; it is also known as the Temple of Quetzalcoatl and the Feathered Serpent Pyramid.

Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, granting them a high viscosity. The high viscosity inhibits atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muon
A muon ( ; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 '' e'' and a spin of , but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles; that is, it is a fundamental particle. The muon is an unstable subatomic particle with a mean lifetime of , much longer than many other subatomic particles. As with the decay of the non-elementary neutron (with a lifetime around 15 minutes), muon decay is slow (by subatomic standards) because the decay is mediated only by the weak interaction (rather than the more powerful strong interaction or electromagnetic interaction), and because the mass difference between the muon and the set of its decay products is small, providing few kinetic degrees of freedom for decay. Muon decay almost always produces at least three particles, which must include an electron o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aztec Mythology
Aztec mythology is the body or collection of myths of the Aztec civilization of Central Mexico. The Aztecs were Nahuatl-speaking groups living in central Mexico and much of their mythology is similar to that of other Mesoamerican cultures. According to legend, the various groups who were to become the Aztecs arrived from the north into the Anahuac valley around Lake Texcoco. The location of this valley and lake of destination is clear – it is the heart of modern Mexico City – but little can be known with certainty about the origin of the Aztec. There are different accounts of their origin. In the myth the ancestors of the Mexica/Aztec came from a place in the north called Aztlan, the last of seven ''nahuatlacas'' (Nahuatl-speaking tribes, from ''tlaca'', "man") to make the journey southward, hence their name "Azteca." Other accounts cite their origin in Chicomoztoc, "the place of the seven caves," or at Tamoanchan (the legendary origin of all civilizations). The Mexic ...
