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 ...

UNESCO World Heritage List
World Heritage Sites are landmarks and areas with legal protection under an international treaty administered by UNESCO for having cultural, historical, or scientific 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 is nominated by its host country and determined by the UNESCO's World Heritage Committee to be a unique landmark which is geographically and historically identifiable, having a special cultural or physical significance, and to be under a sufficient system of legal protection. World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains or wilderness areas, and others. A World Heritage Site may signify a remarkable accomplishment of humankind and serve as evidence of humanity's intellectual history on the planet, or it might be a place of great natur ...

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. Produced from felsic lava, obsidian is 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, giving them a high viscosity. The high viscosity inhibits the 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 s ... [...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 re ... [...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 famou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altar
An altar is a table or platform for the presentation of religion, religious offerings, for sacrifices, or for other ritualistic purposes. Altars are found at shrines, temples, Church (building), churches, and other places of worship. They are used particularly in Christianity, Buddhism, Hinduism, and modern paganism. Many historical-medieval faiths also made use of them, including the Religion in ancient Rome, Roman, Religion in ancient Greece, Greek, and Norse paganism, Norse religions. Etymology The modern English language, English word ''wikt:altar#English, altar'' was derived from Middle English ''wikt:alter#Latin, altar'', from Old English ''wikt:alter, alter'', taken from Latin ''wikt:altare#Latin, altare'' ("altar"), probably related to ''wikt:adolere#Etymology 2, adolere'' ("burn"); thus "burning place", influenced by ''wikt:altus#Latin, altus'' ("high"). It displaced the native Old English word ''wikt:weofod#Old English, wēofod''. Altars in antiquity In antiquity, alta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milpa
In agriculture, a milpa is a field for growing food crops and a crop-growing system used throughout Mesoamerica, especially in the Yucatán Peninsula, in Mexico. The word ''milpa'' derives from the Nahuatl words ''milli'' and ''pan''. Based on the agronomy of the Maya and of other Mesoamerican peoples, the ''milpa'' system is used to produce crops of maize, beans, and squash without employing artificial pesticides and artificial fertilizers. The land-conservation cycle of the milpa is two years of cultivation and eight years of laying fallow. In the Mexican states of Jalisco and Michoacán and in central Mexico as well as Guanacaste Province Costa Rica, as an agricultural term ''milpa'' denotes a single corn plant; in El Salvador and Guatemala, ''milpa'' specifically refers to harvested crop of maize and the field for cultivation. The concept of ''milpa'' is a sociocultural construct rather than simply a system of agriculture. It involves complex interactions and relationship ...

Temazcal
A temazcal is a type of sweat lodge, which originated with 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 A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them togethe ...

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 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 millennia, 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 21st cen ...

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 Richter in collaboration with Beno Gutenberg, and presented in Richter's 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 common logarithms simply to make the measurements mana ...

Theobroma Cacao
''Theobroma cacao'' (cacao tree or cocoa tree) is a small ( tall) evergreen tree in the Malvaceae family. Its seedscocoa beansare used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Although the tree is native to the tropics of the Americas, the largest producer of cocoa beans in 2022 was Ivory Coast. The plant's leaf, leaves are alternate, entire, unlobed, long and broad. Description Flowers The flowers are produced in clusters directly on the Trunk (botany), trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink Calyx (botany), 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 Butterfly, butterflies/moths (Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' biting midges. Using the natural pollinator ''Forcipomyia'' midges produced more fruit tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave
''Agave'' (; ; ) is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large Rosette (botany), rosettes of strong, fleshy leaves. 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 semelparity, flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Along with plants from the closely related genera ''Yucca'', ''Hesperoyucca'', and ''Hesperaloe,'' various ''Agave'' species are popular ornamental plants in hot, dry climates, as they require very little supplemental water to survive. Most ''Agave'' species grow very slowly. Some ''Agave'' species are known by the common name "century plant". is a Spanish word that refers to all of the large-leafed pla ...
