Río Azul
Río Azul is an archaeological site of the Pre-Columbian Maya civilization. It is the most important site in the Río Azul National Park in the Petén Department of northern Guatemala, close to the borders of Mexico and Belize. Río Azul is situated to the southeast of the Azul river and its apogee dates to the Early Classic period (c. AD 250–600). The earliest major architecture dates to around 500 BC, in the Late Preclassic period (c. 350 BC – AD 250). In the late 4th century AD Río Azul was dominated by the city of Tikal and its great central Mexican ally Teotihuacan. Tikal used Río Azul to secure an important trade route to the Caribbean Sea and challenge Calakmul, its great rival. The city was largely abandoned in the 6th century but saw a resurgence in the Late Classic (c. AD 600–900), probably as a result of repopulation by Kinal. Location The ruins are situated immediately southeast of the Río Azul ("Blue River") upon a low ridge in the extreme northeast of ...

Petén Department
Petén is a department of Guatemala. It is geographically the northernmost department of Guatemala, as well as the largest by area at it accounts for about one third of Guatemala's area. The capital is Flores. The population at the mid-2018 official estimate was 595,548. Geography The Petén department is bordered on the east by Belize and by Mexico (with the Mexican states of Chiapas to the west, Tabasco to the northwest and Campeche to the north). To the south it borders the Guatemalan departments of Alta Verapaz and Izabal.ITMB Publishing Ltd. 2005. Much of the western border with Mexico is formed by the Usumacinta River and its tributary the Salinas River. Portions of the southern border of the department are formed by the rivers Gracias a Dios and Santa Isabel. The Petén lowlands are formed by a densely forested low-lying limestone plain featuring karstic topography. The area is crossed by low east-west oriented ridges of Cenozoic limestone and is characterised by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feudal
Feudalism, also known as the feudal system, was the combination of the legal, economic, military, cultural and political customs that flourished in Middle Ages, medieval Europe between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships that were derived from the holding of land in exchange for service or labour. Although it is derived from the Latin word ''feodum'' or ''feudum'' (fief), which was used during the Medieval period, the term ''feudalism'' and the system which it describes were not conceived of as a formal political system by the people who lived during the Middle Ages. The classic definition, by François Louis Ganshof (1944),François Louis Ganshof (1944). ''Qu'est-ce que la féodalité''. Translated into English by Philip Grierson as ''Feudalism'', with a foreword by F. M. Stenton, 1st ed.: New York and London, 1952; 2nd ed: 1961; 3rd ed.: 1976. describes a set of reciprocal legal and Medieval warfare, military ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoamerican Long Count Calendar
The Mesoamerican Long Count calendar is a non-repeating, vigesimal (base 20) and octodecimal (base 18) calendar used by several pre-Columbian Mesoamerican cultures, most notably the Maya. For this reason, it is often known as the Maya (or Mayan) Long Count calendar. Using a modified vigesimal tally, the Long Count calendar identifies a day by counting the number of days passed since a mythical creation date that corresponds to August 11, 3114 BCE in the proleptic Gregorian calendar. The Long Count calendar was widely used on monuments. Background The two most widely used calendars in pre-Columbian Mesoamerica were the 260-day Tzolkʼin and the 365-day Haabʼ. The equivalent Aztec calendars are known in Nahuatl as the Tonalpohualli and Xiuhpohualli. The combination of a Haabʼ and a Tzolkʼin date identifies a day in a combination which does not occur again for 18,980 days (52 Haabʼ cycles of 365 days equals 73 Tzolkʼin cycles of 260 days ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puuc
Puuc is the name of either a region in the Mexican state of Yucatán or a Maya architectural style prevalent in that region. The word ''puuc'' is derived from the Maya term for "hill". Since the Yucatán is relatively flat, this term was extended to encompass the large karstic range of hills in the southern portion of the state, hence, the terms Puuc region or Puuc hills. The Puuc hills extend into northern Campeche and western Quintana Roo. The term Puuc is also used to designate the architectural style of ancient Maya sites located within the Puuc hills, hence, the term Puuc architecture. This architectural style began at the end of the Late Classic period but experienced its greatest extent during the Terminal Classic period. Puuc architecture In the florescence of Puuc architecture (such as at the ancient Maya site of Uxmal) buildings were decorated with carefully cut veneer stones set into a concrete core. The lower portion of the façades are blank with a flat surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chultun
A chultun (plural: ''chultunob''' or ''chultuns'') is a bottle-shaped underground storage chamber built by the pre-Columbian Maya in southern Mesoamerica. Their entrances were surrounded by plastered aprons which guided rainwater into them during the rainy seasons. Most of these archaeological features likely functioned as cisterns for potable water. Chultunob' were typically constructed in locations where naturally occurring ''cenotes'' were absent (such as the Puuc hills, which sit hundreds of feet above the Yucatán Peninsula aquifer). While many were constructed to collect water, not all may have served that purpose. Some chultuns may have been used for storage of perishable comestibles or for the fermentation of alcoholic beverages. Experimental research conducted in the 1960s by Mayanist Dennis E. Puleston demonstrated that chultuns around Tikal were particularly effective for long-term storage of ramon nuts ( Brosimum alicastrum). After a chultun ended its usefulnes ...

Mesoamerican Pyramids
Mesoamerican pyramids form a prominent part of ancient Mesoamerican architecture. Although similar in some ways to Egyptian pyramids, these New World structures have flat tops (many with temples on the top) and stairs ascending their faces. The largest pyramid in the world by volume is the Great Pyramid of Cholula, in the east-central Mexican state of Puebla. The builders of certain classic Mesoamerican pyramids have decorated them copiously with stories about the Maya Hero Twins, Hero Twins, the feathered serpent Quetzalcoatl, Mesoamerican creation myths, ritualistic sacrifice, etc. written in the form of hieroglyphs on the rises of the steps of the pyramids, on the walls, and on the sculptures contained within. Aztec pyramids The Aztecs dominated central Mexico in the 14th, 15th and 16th centuries. Their capital was Tenochtitlan on the shore of Lake Texcoco – the site of modern-day Mexico City. They were related to the preceding cultures in the basin of Mexico such as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacbe
Sacbe at Dzibilchaltun in the Yucatán Arch at the end of the sacbé, Kabah, Yucatán A sacbe, plural sacbeob (Yucatec Maya: singular ''sakbej'', plural ''sakbejo'ob''), or "white way", is a raised paved road built by the Maya civilization of pre-Columbian Mesoamerica. Most connect temples, plazas, and groups of structures within ceremonial centers or cities, but some longer roads between cities are also known. The term "sacbe" is Yucatec Maya for "white road"; white perhaps because there is evidence that they were originally coated with limestone stucco or plaster, which was over a stone and rubble fill.Roys and Shook 1966, 43 Etymology The word "Beh" operates as the root term for "Sacbe" it is a Mayan term for "road, pathway, or trail." Beh is spelled alternately as Be, bej, bey, be, bih, as well as "beel" in the possessive. It has many distinctions from English concepts of roads, pathways, or trails. Beh's metaphoric meanings are just as important if not more important tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talud-tablero
Talud-tablero is an architectural style most commonly used in platforms, temples, and pyramids in Pre-Columbian Mesoamerica, becoming popular in the Early Classic Period of Teotihuacan. ''Talud-tablero'' consists of an inward-sloping surface or panel called the ''talud'', with a panel or structure perpendicular to the ground sitting upon the slope called the ''tablero''. This may also be referred to as the slope-and-panel style. Cultural significance Talud-tablero was often employed in pyramid construction, found in Pre-Columbian Mesoamerica. It is found in many cities and cultures but is strongly associated with the Teotihuacan culture of central Mexico, where it is a dominant architectural style. Talud-tablero's appearance in many cities during and after Teotihuacan's apogee is thought to be indicative of the city's powerful influence in Mesoamerica as a trade, art, and cultural center, with the architectural style serving to either emulate Teotihuacan or affiliate the cities ...

Yax Nuun Ayiin I
Yax Nuun Ahiin I, also known as Curl Snout and Curl Nose (died 17 June 404?), was a 4th-century ruler of the Maya city of Tikal. His name when transcribed is YAX-?-AH:N, translated "First ? Crocodile". He took the throne on 12 September 379, and reigned until his death.These are the dates indicated on the Maya inscriptions in Mesoamerican Long Count calendar, Accession: 8.17.2.16.17 5 Kaban 10 Yaxk'jn and Death: 8.18.8.1.2 2 Ik' 10 Sip, Martin & Grube 2008, p. 32 He is referred to by the Mayan title ''ajaw'', meaning ''lord''. Biography Yax Nuun Ayiin I was a son of Spearthrower Owl, a lord of Teotihuacan (probably that city's king) in central Mexico. The installation of a Teotihuacano noble on the throne of Tikal marks a high point of Teotihuacan influence in the central Maya lowlands. Yax Nuun Ahiin I may have been a child or youth at the time of his coronation, and the early years of his reign seems to have been dominated by one of his father's generals, Sihyaj K'ahk', in a so ...
