Lago De Texcoco
Lake Texcoco ( es, Lago de Texcoco) was a natural lake within the "Anahuac" or Valley of Mexico. Lake Texcoco is best known as where the Aztecs built the city of Tenochtitlan, which was located on an island within the lake. After the Spanish conquest of the Aztec Empire, efforts to control flooding by the Spanish led to most of the lake being drained. The entire lake basin is now almost completely occupied by Mexico City, the capital of the present-day nation of Mexico. Drainage of the lake has led to serious ecological and human consequences: the local climate and water availability have changed considerably, contributing to water scarcity in the area; subsequent groundwater extraction leads to land subsidence under much of the city; and native species endemic to the lake region have become severely endangered or extinct due to ecosystem change, such as the axolotl. After the cancellation of the Mexico City Texcoco Airport, the government initiated a major restoration project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluvial Lake
A pluvial lake is a body of water that accumulated in a basin because of a greater moisture availability resulting from changes in temperature and/or precipitation. These intervals of greater moisture availability are not always contemporaneous with glacial periods. Pluvial lakes are typically closed lakes that occupied endorheic basins. Pluvial lakes that have since evaporated and dried out may also be referred to as ''paleolakes''.Goudie, A.S., 2013. ''and semi-arid geomorphology.'' Cambridge University Press. Etymology The word comes from the Latin ''pluvia'', which means "rain". Geology Pluvial lakes represent changes in the hydrological cycle: wet cycles generate large lakes, and dry cycles cause the lakes to recede. Accumulated sediments show the variation in water level. During glacial periods, when the lake level is fairly high, mud sediments will settle out and be deposited. At times in between glaciers (interglacial), salt deposits may be present because of the ari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontological Museum In Tocuila
The Paleontological Museum in Tocuila (Museo Paleontológico en Tocuila) is a fossil museum located in Municipality of Texcoco, State of Mexico, central Mexico. It displays part of one of the richest deposits of Late Pleistocene fauna in America. International groups of archeologists discovered a large quantity of bones, mainly mammoth remains, estimated to be 11,000 to 12,000 years old, in an ancient river mouth that used to flow into the Lake Texcoco. Location The Paleontological Museum in Tocuila is located on the street ''16 de Septiembre'', between streets ''Morelos'' and ''Benito Juárez'', in the community of San Miguel Tocuila near Texcoco, History The discovery of the site happened by chance in 1996.Claus Siebe, Peter Schaaf und Jaime Urrutia-Fucugauchi: ''Mammoth bones embedded in a late Pleistocene lahar from Popocatepetl Volcano, near Tocuila, central Mexico.'GSA Bulletin, October 1999, v. 111, no. 10, p. 1550-1562/ref> While Joaquín Ramírez was overseeing the ex ...

Painting Of Tenochtitlan-Tlatelolco On Lake Texcoco (9755215791)
Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term ''painting ''describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate multiple other materials, including sand, clay, paper, plaster, gold leaf, and even whole objects. Painting is an important form in the visual arts, bringing in elements such as drawing, composition, gesture (as in gestural painting), narration (as in narrative art), and abstraction (as in abstract art). Paintings can be naturalistic and representational (as in still life and landscape painting), photographic, abstract, nar ...

Chichimeca
Chichimeca () is the name that the Nahua peoples of Mexico generically applied to nomadic and semi-nomadic peoples who were established in present-day Bajio region of Mexico. Chichimeca carried the meaning as the Roman term "barbarian" that described Germanic tribes. The name, with its pejorative sense, was adopted by the Spanish Empire. For the Spanish, in the words of scholar Charlotte M. Gradie, "the Chichimecas were a wild, nomadic people who lived north of the Valley of Mexico. They had no fixed dwelling places, lived by hunting, wore little clothes and fiercely resisted foreign intrusion into their territory, which happened to contain silver mines the Spanish wished to exploit." In spite of not having temples or idols, they practiced animal sacrifice, and they were feared for their expertise and brutality in war. The Spanish invasion resulted in a "drastic population decline of all the peoples known collectively as Chichimecas, and to the eventual disappearance as peoples ...

Toltec
The Toltec culture () was a Pre-Columbian era, pre-Columbian Mesoamerican culture that ruled a state centered in Tula (Mesoamerican site), Tula, Hidalgo (state), Hidalgo, Mexico, during the Epiclassic and the early Post-Classic period of Mesoamerican chronology, reaching prominence from 950 to 1150 CE. The later Aztec culture saw the Toltecs as their intellectual and cultural predecessors and described Toltec culture emanating from Tollan, ''Tōllān'' (Nahuatl language, Nahuatl for Tula) as the epitome of civilization; in the Nahuatl language the word ''Tōltēkatl'' (singular) or ''Tōltēkah'' (plural) came to take on the meaning "artisan". The Aztec oral tradition, oral and pictographic tradition also described the history of a Toltec Empire, giving lists of rulers and their exploits. Modern scholars debate whether the Aztec narratives of Toltec history should be given credence as descriptions of actual historical events. While all scholars acknowledge that there is a lar ...

Tlacopan
Tlacopan, also called Tacuba, was a Tepanec / Mexica altepetl on the western shore of Lake Texcoco. The site is today the neighborhood of Tacuba, in Mexico City. Etymology The name comes from Classical Nahuatl ''tlacōtl'', "stem" or "rod" and ''-pan'', "place in or on" and roughly translates to "place on the rods"), History Tlacopan was a Tepanec subordinate city-state to nearby altepetl, Azcapotzalco. In 1428, after its successful conquest of Azcapotzalco, Tlacopan allied with the neighbouring city-states of Tenochtitlan and Texcoco, thus becoming a member of the Aztec Triple Alliance and resulting in the subsequent birth of the Aztec Empire.León-Portilla, M. 1992, 'The Broken Spears: The Aztec Accounts of the Conquest of Mexico.'' Boston: Beacon Press, Aculnahuacatl Tzaqualcatl, the son of the Tepanec ruler, Tezozomoc, was installed as tlatoani of Tlacopan until his death in c.1430. Throughout its existence, Tlacopan was to remain a minor polity within the Triple Allia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azcapotzalco (altepetl)
Azcapotzalco was a pre-Columbian Nahua ''altepetl'' (state), capital of the Tepanec empire, in the Valley of Mexico, on the western shore of Lake Texcoco. The name ''Azcapotzalco'' means "at the anthill" in Nahuatl. Its inhabitants were called ''Azcapotzalca''. According to the 17th century annalist Chimalpahin, Azcapotzalco was founded by Chichimecs in the year 995 AD. The most famous ruler (''tlatoani'') of Azcapotzalco was Tezozomoctli. History According to chronicler Fernando Alva Ixtlilxóchitl, the Tepanecs were a Chichimec group that settled in 1012 in the region west of Lake Texcoco. Their lineage began when their Acolhua leader (or Acolnahuacatl) married Xolotl's daughter Cuetlaxochitzin. But this information is apocryphal, since Acolnahuacatl's life is considered to have occurred much later. Chimalpahin places their settlement before, in 995. In fact, archaeological investigations have revealed that Azcapotzalco was inhabited since the Classical period — around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teotihuacan
Teotihuacan (Spanish language, Spanish: ''Teotihuacán'') (; ) is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, which is located in the State of Mexico, northeast of modern-day Mexico City. Teotihuacan is known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas, namely Pyramid of the Sun and Pyramid of the Moon. At its zenith, perhaps in the first half of the first millennium (1 CE to 500 CE), Teotihuacan was the largest city in the Americas, with a population estimated at 125,000 or more, making it at least the sixth-largest city in the world during its epoch. The city covered eight square miles (21 km2), and 80 to 90 percent of the total population of the valley resided in Teotihuacan. Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds, the Avenue of the Dead, and its vibrant, well-prese ...

Pyramid
A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above. This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. For thousands of years, the largest structures on Earth were pyrami ...

Cuicuilco
Cuicuilco is an important archaeological site located on the southern shore of Lake Texcoco in the southeastern Valley of Mexico, in what is today the borough of Tlalpan in Mexico City. Some historians believe this settlement goes back to 1400 BC.PASTRANA, Alejandro and Patricia Fournier''Cuicuilco. In The Oxford Encyclopedia of Mesoamerican Cultures''.The Civilizations of Mexico and Central America. Vol. 1. David Carrasco (ed.), pp. 290–292. New York: Oxford University Press. 2001 Other historians believe the pyramid could be the oldest building in the Americas circa 6,500 BC. Cuicuilco flourished during the Mesoamerican Middle and Late Formative (c. 700 BCE – 150 CE) periods. Today, it is a significant archaeological site that was occupied during the Early Formative until its destruction in the Late Formative. Based on its date of occupation, Cuicuilco may be the oldest city in the Valley of Mexico and was roughly contemporary with, and possibly interacting with, the Olm ...

Tlatilco Culture
Tlatilco culture is a culture that flourished in the Valley of Mexico between the years 1250 BCE and 800 BCE, during the Mesoamerican Early Formative period. Tlatilco, Tlapacoya, and Coapexco are the major Tlatilco culture sites. Tlatilco culture shows a marked increase in specialization over earlier cultures, including more complex settlement patterns, specialized occupations, and stratified social structures. In particular, the development of the chiefdom centers at Tlatilco and Tlapacoya is a defining characteristic of Tlatilco culture. This period also saw a significant increase in long distance trade, particularly in iron ore, obsidian, and greenstone, trade which likely facilitated the Olmec influence seen within the culture, and may explain the discovery of Tlatilco-style pottery near Cuautla, Morelos, to the south. Defining the Tlatilco culture Archaeologically, the advent of the Tlatilco culture is denoted by a widespread dissemination of artistic conventions, ...

Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...
