Sascab
Sascab is a naturally occurring mineral material described variously as "decomposed limestone", " breccia", and "the lime gravel mixture the Maya used as mortar." It has been used as a building and paving material in Mesoamerica since antiquity. In the context of pottery the term may also apply to mixtures (with clay and water) of a more finely divided form of the same material (described as "stone dust"). It was used by the ancient Maya in place of (or as a partial replacement for) lime in some applications, without needing to be "burned." According to travel writer Jeanine Kitchel, the American explorer of the Yucatan, Edward Herbert Thompson found (ca.1900) "shallow quarries near Chichen Itza Chichen Itza , es, Chichén Itzá , often with the emphasis reversed in English to ; from yua, Chiʼchʼèen Ìitshaʼ () "at the mouth of the well of the Itza people" was a large pre-Columbian city built by the Maya people of the Terminal ... with worked veins of ''sasca ...

Lime (material)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

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] |
Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since otherwise th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maya Civilization
The Maya civilization () of the Mesoamerican people is known by its ancient temples and glyphs. Its Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. It is also noted for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors. The Archaic period, before 2000 BC, saw the first developments in agricul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoamerica
Mesoamerica is a historical region and cultural area in southern North America and most of Central America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. Within this region pre-Columbian societies flourished for more than 3,000 years before the Spanish colonization of the Americas. Mesoamerica was the site of two of the most profound historical transformations in world history: primary urban generation, and the formation of New World cultures out of the long encounters among indigenous, European, African and Asian cultures. In the 16th century, Eurasian diseases such as smallpox and measles, which were endemic among the colonists but new to North America, caused the deaths of upwards of 90% of the indigenous people, resulting in great losses to their societies and cultures. Mesoamerica is one of the five areas in the world where ancient civilization arose independently (see cradle of civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pottery
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural "potteries"). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were ...

Edward Herbert Thompson
Edward Herbert Thompson (September 28, 1857 – May 11, 1935) was an American-born archaeologist and long-time consul to Yucatán, Mexico. Biography Edward H. Thompson was born in Worcester, Massachusetts. Thompson devoted much of his career to study of the Maya civilization. In 1879, ''Popular Science Monthly'' published "Atlantis Not a Myth", an article by Thompson in which he argued that the indigenous civilizations of North and Central America could be remnants of the lost continent of Atlantis.Edward H. Thompson,, ''Popular Science Monthly'', October 1879 The article attracted the attention of Stephen Salisbury III, a wealthy Worcester resident, Mayanist, and principal benefactor of the American Antiquarian Society. Salisbury, along with fellow AAS members The Rev. Edward Everett Hale and Massachusetts Senator George Frisbie Hoar, persuaded Thompson to move to Yucatán to explore the Maya ruins in exchange for receiving an appointment as American Consul. Thompson arrived in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chichen Itza
Chichen Itza , es, Chichén Itzá , often with the emphasis reversed in English to ; from yua, Chiʼchʼèen Ìitshaʼ () "at the mouth of the well of the Itza people" was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archeological site is located in Tinúm Municipality, Yucatán State, Mexico. Chichen Itza was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the Northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural ...

Mesoamerican Architecture
Mesoamerican architecture is the set of architectural traditions produced by pre-Columbian cultures and civilizations of Mesoamerica, traditions which are best known in the form of public, ceremonial and urban monumental buildings and structures. The distinctive features of Mesoamerican architecture encompass a number of different regional and historical styles, which however are significantly interrelated. These styles developed throughout the different phases of Mesoamerican history as a result of the intensive cultural exchange between the different cultures of the Mesoamerican culture area through thousands of years. Mesoamerican architecture is mostly noted for its pyramids, which are the largest such structures outside of Ancient Egypt. One interesting and widely researched topic is the relation between cosmovision, religion, geography, and architecture in Mesoamerica. Much seems to suggest that many traits of Mesoamerican architecture were governed by religious and mytho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maya Architecture
Maya architecture spans several thousands of years, several eras of political change, and architectural innovation before the Spanish colonization of the Americas. Often, the buildings most dramatic and easily recognizable as creations of the Maya peoples are the step pyramids of the Terminal Preclassic Maya period and beyond. Based in general Mesoamerican architectural traditions, the Maya utilized geometric proportions and intricate carving to build everything from simple houses to ornate temples. This article focuses on the more well-known pre-classic and classic examples of Maya architecture. The temples like the ones at Palenque, Tikal, and Uxmal represent a zenith of Maya art and architecture. Through the observation of numerous elements and stylistic distinctions, remnants of Maya architecture have become an important key to understanding their religious beliefs and culture as a whole.
