Tunnels Of San Antonio
The tunnels of San Antonio are located in the province of Luya, Peru. They are rocky formations like natural bridges placed over San Antonio river. An archaeological cave painting was documented in 1986 in the place of San Antonio ( Luya), by one of the Antisuyo expeditions organized by the Amazon Archaeology Institute. It is constituted in the first sample of authentic cave painting detected in the Amazonian Andes and, in general, in the Peruvian mountain range. It is not a question, in effect, of a rock painting but of a painting executed on a wall. Also its lines are very different from the typical ones used by rock art; what can be realized by the high grade of naturalism with which the personages' faces were painted. The cave painting of San Antonio was not seen by the experts who went along formerly along the place, as Langlois or the archaeologists Reichlen. This is not only because they passed through San Antonio hurriedly, but because all the paintings are only pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luya Province
Luya is located in the south and west part of the department of Amazonas in Peru. Its territory, which partly is ceja de selva, is crossed by branches of the Cordillera Central (namely the Cordillera Blanca) and the Oriental of the Andes, being rasped by deep streams, high pampas and snowed summit. It deserved to be named the streams of Hoyada Grande and Luya, the fertile valleys of Pizuquia and Cesuya, as well as the snow-capped mountains of Shube, Mesón and Santa Clara located in the Cordillera Oriental. Its principal rivers are: * Marañon that flows from south to northwest and forms its extensive west limit with the department of Cajamarca * Utcubamba, which runs from south to north-east and forms its east boundary with the provinces of Chachapoyas and Bongará * Magunchal, which is born in the heights of the district of Colcamar, runs from south to north and ends into the Utcubamba, forming its most extensive and rich agricultural zone. The province was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochre
Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous iron ...

Horn (anatomy)
A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae (pronghorn) and Bovidae (cattle, goats, antelope etc.). Cattle horns arise from subcutaneous connective tissue (under the scalp) and later fuse to the underlying frontal bone. One pair of horns is usual; however, two or more pairs occur in a few wild species and in some domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro. Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, which shed the ...

Architectural Conservation
Conservation and restoration of immovable cultural property describes the process through which the material, historical, and design integrity of any Cultural property, immovable cultural property are prolonged through carefully planned interventions. The individual engaged in this pursuit is known as an architectural conservator-restorer. Decisions of when and how to engage in an intervention are critical to the ultimate conservation-restoration of cultural heritage. Ultimately, the decision is value based: a combination of artistic, contextual, and informational values is normally considered. In some cases, a decision to not intervene may be the most appropriate choice. Definitions Narrow definition The Conservation Architect must consider factors that deal with issues of prolonging the life and preserving the integrity of architectural character, such as form and style, and/or its constituent materials, such as stone, brick, glass, metal, and wood. In this sense, the term re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dance
Dance is a performing art form consisting of sequences of movement, either improvised or purposefully selected. This movement has aesthetic and often symbolic value. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin. An important distinction is to be drawn between the contexts of theatrical and participatory dance, although these two categories are not always completely separate; both may have special functions, whether social, ceremonial, competitive, erotic, martial, or sacred/liturgical. Other forms of human movement are sometimes said to have a dance-like quality, including martial arts, gymnastics, cheerleading, figure skating, synchronized swimming, marching bands, and many other forms of athletics. There are many professional athletes like, professional football players and soccer players, who take dance classes to help with their skills. To be more specific professional athlet ...

Stack (geology)
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. britannica.com They are formed when part of a headland is by , which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, formi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorge
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcophagus
A sarcophagus (plural sarcophagi or sarcophaguses) is a box-like funeral receptacle for a corpse, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word ''sarcophagus'' comes from the Greek σάρξ ' meaning "flesh", and φαγεῖν ' meaning "to eat"; hence ''sarcophagus'' means "flesh-eating", from the phrase ''lithos sarkophagos'' ( λίθος σαρκοφάγος), "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to rapidly facilitate the decomposition of the flesh of corpses contained within it due to the chemical properties of the limestone itself. History of the sarcophagus Sarcophagi were most often designed to remain above ground. The earliest stone sarcophagi were used by Egyptian pharaohs of the 3rd dynasty, which reigned from about 2686 to 2613 B.C. The Hagia Triada sarcophagus is a stone sarcophagus elaborately painted in fresco; one style of later A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semicircle
In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, radians, or a half-turn). It has only one line of symmetry (reflection symmetry). In non-technical usage, the term "semicircle" is sometimes used to refer to a half-disk, which is a two-dimensional geometric shape that also includes the diameter segment from one end of the arc to the other as well as all the interior points. By Thales' theorem, any triangle inscribed in a semicircle with a vertex at each of the endpoints of the semicircle and the third vertex elsewhere on the semicircle is a right triangle, with a right angle at the third vertex. All lines intersecting the semicircle perpendicularly are concurrent at the center of the circle containing the given semicircle. Uses A semicircle can be used to construct the arithmetic and geometric means of two lengths using straight-e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
