Joya De Cerén
Joya de Cerén (''Jewel of Cerén'' in the Spanish language) is an archaeological site in La Libertad Department, El Salvador, featuring a pre-Columbian Maya farming village. The ancient Maya site of Joya de Cerén is located in the Zapotitán Valley, 36 kilometers northwest of San Salvador, El Salvador.Castellanos, p. 94. It is often referred to as the "Pompeii of the Americas", in comparison to the famed Ancient Roman ruins. This site is known for the excellent preservation of a Classic period settlement that was rapidly buried by the ashfall of an eruption of the Loma Caldera around AD 600. The relative abundance of paleoethnobotanical remains recovered at Joya de Cerén in comparison to other ancient Maya archaeological sites make Joya de Cerén particularly significant in the study of everyday life of ancient Maya agricultural communities. Of importance was the discovery of a manioc field, the first instance of manioc cultivation identified at a New World archaeological si ...

La Libertad Department (El Salvador)
La Libertad () is one of the departments of El Salvador and is located in the southwest of the country. The capital is Santa Tecla. It has area 1,653 km² and a population of more than 747,600 people. History It was classified as a department on January 28, 1865. The population was settled on the Ulliman Plains, which is where rubber is harvested. The city was called "Nueva Ciudad de San Salvador" (New City of San Salvador) and made the department's capital on the same date as the department was declared. The department's capital was renamed Santa Tecla on December 22, 2003. The agricultural products that are cultivated are the basic grains, balsam, sugar cane, coffee, grass, hortensia, cocoa, and fruits. They also develop the bovine, equine and pig cattle, the raising of poultry and beekeeping.

UNESCO World Heritage List
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. As ...

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] |
Plan Of Joya De Cerén
A plan is typically any diagram or list of steps with details of timing and resources, used to achieve an objective to do something. It is commonly understood as a temporal set of intended actions through which one expects to achieve a goal. For spatial or planar topologic or topographic sets see map. Plans can be formal or informal: * Structured and formal plans, used by multiple people, are more likely to occur in projects, diplomacy, careers, economic development, military campaigns, combat, sports, games, or in the conduct of other business. In most cases, the absence of a well-laid plan can have adverse effects: for example, a non-robust project plan can cost the organization time and money. * Informal or ad hoc plans are created by individuals in all of their pursuits. The most popular ways to describe plans are by their breadth, time frame, and specificity; however, these planning classifications are not independent of one another. For instance, there is a close rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoard
A hoard or "wealth deposit" is an archaeological term for a collection of valuable objects or artifacts, sometimes purposely buried in the ground, in which case it is sometimes also known as a cache. This would usually be with the intention of later recovery by the hoarder; hoarders sometimes died or were unable to return for other reasons (forgetfulness or physical displacement from its location) before retrieving the hoard, and these surviving hoards might then be uncovered much later by metal detector hobbyists, members of the public, and archaeologists. Hoards provide a useful method of providing dates for artifacts through association as they can usually be assumed to be contemporary (or at least assembled during a decade or two), and therefore used in creating chronologies. Hoards can also be considered an indicator of the relative degree of unrest in ancient societies. Thus conditions in 5th and 6th century Britain spurred the burial of hoards, of which the most famous a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altar
An altar is a table or platform for the presentation of religious offerings, for sacrifices, or for other ritualistic purposes. Altars are found at shrines, temples, churches, and other places of worship. They are used particularly in paganism, Christianity, Buddhism, Hinduism, Judaism, modern paganism, and in certain Islamic communities around Caucasia and Asia Minor. Many historical-medieval faiths also made use of them, including the Roman, Greek, and Norse religions. Etymology The modern English word '' altar'' was derived from Middle English '' altar'', from Old English '' alter'', taken from Latin '' altare'' ("altar"), probably related to '' adolere'' ("burn"); thus "burning place", influenced by '' altus'' ("high"). It displaced the native Old English word '' wēofod''. Altars in antiquity File:Tel Be'er Sheva Altar 2007041.JPG, Horned altar at Tel Be'er Sheva, Israel.

Milpa
Milpa is a crop-growing system used throughout Mesoamerica. It has been most extensively described in the Yucatán peninsula area of Mexico. The word ''milpa'' is derived from the Nahuatl word phrase ''mil-pa'', which translates into "cultivated field." Though different interpretations are given to it, it usually refers to a cropping field. Based on the ancient agricultural methods of Maya peoples and other Mesoamerican people, ''milpa'' agriculture produces maize, beans, and squash. The milpa cycle calls for 2 years of cultivation and eight years of letting the area lie fallow. Agronomists point out that the system is designed to create relatively large yields of food crops without the use of artificial pesticides or fertilizers, and they point out that while it is self-sustaining at current levels of consumption, there is a danger that at more intensive levels of cultivation the milpa system can become unsustainable. The word is also used for a small field, especially in Mexico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temazcal
A temazcal is a type of sweat lodge, which originated with pre-Hispanic indigenous peoples in Mesoamerica. The term ''temazcal'' comes from the Nahuatl language, either from the words (to bathe) and (house), or from the word (house of heat). Overview In ancient Mesoamerica it was used as part of a curative ceremony thought to purify the body after exertion such as after a battle or a ceremonial ball game. It was also used for healing the sick, improving health, and for women to give birth. It continues to be used today in Indigenous cultures of Mexico and Central America that were part of the ancient Mesoamerican region for spiritual healing and health enrichment reasons. The temazcal is usually a permanent structure, unlike sweat lodges of other regions. It has various construction styles differing by region; from volcanic rock and cement adobe mud bricks even wood mud and cloth can be utilized. It may be a circular dome made to represent the uterus, although rectangular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hearths
A hearth () is the place in a home where a fire is or was traditionally kept for home heating and for cooking, usually constituted by at least a horizontal hearthstone and often enclosed to varying degrees by any combination of reredos (a low, partial wall behind a hearth), fireplace, oven, smoke hood, or chimney. Hearths are usually composed of masonry such as brick or stone. For centuries, the hearth was such an integral part of a home, usually its central and most important feature, that the concept has been generalized to refer to a homeplace or household, as in the terms "hearth and home" and "keep the home fires burning". In the modern era, since the advent of central heating, hearths are usually less central to most people's daily life because the heating of the home is instead done by a furnace or a heating stove, and cooking is instead done with a kitchen stove/range (combination cooktop and oven) alongside other home appliances; thus many homes built in the 20th and 2 ...

Richter Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Theobroma Cacao
''Theobroma cacao'', also called the cacao tree and the cocoa tree, is a small ( tall) evergreen tree in the family Malvaceae. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. The largest producer of cocoa beans in 2018 was Ivory Coast, 2.2 million tons. Description Its leaves are alternate, entire, unlobed, long and broad. Flowers The flowers are produced in clusters directly on the trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5). While many of the world's flowers are pollinated by bees ( Hymenoptera) or butterflies/moths ( Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' midges in the subfamily Forcipomyiinae. Using the natural pollinator ''Forcipomyia'' midges for ''Theobroma cacao'' was shown to have more fruit production th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...
