Pu O Hiro
Pu o Hiro (which means Hiro's Trumpet) is a stone on Easter Island that was used as a musical instrument by the ancient Rapa Nui. It is also known as Maea Puhi ("stone to blow" or "wind stone"). When blown through its main hole, it would produce a sound that resembled a trumpet. It was used to invoke Hiro, the deity of rain. Description Pu o Hiro is approximately 1 to 1.25 meters tall. It is a stone aerophone. It is an ovoid rock with multiple natural holes. There is one main hole that was used to blow and three outlet holes. The main hole is natural and located at the top of the stone. The stone has multiple petroglyphs. Some include vulva forms known as ''komari'', a symbol of fertility. Uses Pu o Hiro had multiple uses, although it is not clearly defined. It had been used to invoke Hiro, the rain deity. It was also used to summon a gathering of neighbors. It also could have warned of a potential enemy attack. It may also have been fishing talisman, used to make sounds th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oval
An oval () is a closed curve in a plane which resembles the outline of an egg. The term is not very specific, but in some areas of mathematics (projective geometry, technical drawing, etc.), it is given a more precise definition, which may include either one or two axes of symmetry of an ellipse. In common English, the term is used in a broader sense: any shape which reminds one of an egg. The three-dimensional version of an oval is called an ovoid. Oval in geometry The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should ''resemble'' the outline of an egg or an ellipse. In particular, these are common traits of ovals: * they are differentiable (smooth-looking), simple (not self-intersecting), convex, closed, plane curves; * their shape does not depart much from that of ...

Hanga Roa
Hanga Roa (; ) (Rapanui language: ''Long bay'') is the main town, harbour, and seat of Easter Island, a municipality of Chile. It is located in the southern part of the island's west coast, in the lowlands between the extinct volcanoes of Terevaka and Rano Kau. History ''Hanga Roa'' in the native Rapa Nui language means "wide bay" or "long bay". Upon Chile's claim of the island, the Rapa Nui were forced in Hanga Roa, and the rest of the land was leased to a sheep farm.Annie MurphyFor Chile, Colossal Trouble On Easter Island ''Npr.org'', 9 September 2010 (accessed on 31 May 2019) For much of the twentieth century, the rest of the island was leased to the Compañía Explotadora de la Isla de Pascua (CEDIP) (a subsidiary of Williamson-Balfour Company) and closed to the Rapa Nui. Some disagreements between the government of Chile and the Rapa Nui have led the locals with ancestral roots to "take over" many hotels in the city. For the locals, it is a way to draw the line between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertility Rite
Fertility rites are religious rituals that are intended to stimulate reproduction in humans or in the natural world. A group of people performing such rites is a fertility cult. Such rites may involve the sacrifice of "a primal animal, which must be sacrificed in the cause of fertility or even creation". Characteristics "Fertility rites may occur in calendric cycles, as rites of passage within the life cycle, or as ad hoc rituals....Commonly fertility rituals are embedded within larger-order religions or other social institutions." As with cave pictures "hatshow animals at the point of mating... ndserved magic fertility rites", such rites are "...a form of sympathetic magic" in which the forces of nature are to be influenced by the example acted out in the ritual. At times, "ceremonies intended to assure the fecundity of the earth or of a group of women...involve some form of phallic worship".

War Trophy
__NOTOC__ A war trophy is an item taken during warfare by an invading force. Common war trophies include flags, weapons, vehicles, and art. History In ancient Greece and ancient Rome, military victories were commemorated with a display of captured arms and standards. A trophy (from the Greek tropaion) was originally a war memorial assembled from such items on a battlefield. The Roman triumph also displayed these items as well as cultural objects, which later came to be called war trophies. Body parts of slain enemies have sometimes served as trophies since antiquity, in a practice called human trophy collecting. The recovery of Roman eagles taken as trophies by enemy forces sometimes inspired years of added warfare. In more recent times, it has been common for soldiers to return home with souvenirs, such as enemy weapons and flags, while larger military items captured in battle, particularly weaponry such as machine guns and artillery pieces, became the property of the sta ...

Vulva
In mammals, the vulva (: vulvas or vulvae) comprises mostly external, visible structures of the female sex organ, genitalia leading into the interior of the female reproductive tract. For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vulval vestibule, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands (Bartholin's gland, Bartholin's and Skene's gland, Skene's). The folds of the outer and inner labia provide a double layer of protection for the vagina (which leads to the uterus). Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support. Blood supply to the vulva comes from the three pudendal arteries. The internal pudendal veins give drainage. Lymphatic vessel#Afferent vessels, Afferent lymph vessels carry lymph away from the vulva to the inguinal lymph nodes. The nerves that supply the vulva are the pudendal nerve, perineal nerve, ilioinguinal nerve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning " stone", and meaning "carve", and was originally coined in French as . In scholarly texts, a ''petroglyph'' is a rock engraving, whereas a '' petrograph'' (or ''pictograph'') is a rock painting. In common usage, the words are sometimes used interchangeably. Both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by man ...

Aerophone
An aerophone is a musical instrument that produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes (which are respectively chordophones and membranophones), and without the vibration of the instrument itself adding considerably to the sound (or idiophones). According to Curt Sachs: These may be lips, a mechanical reed, or a sharp edge. Also, an aerophone may be excited by percussive acts, such as the slapping of the keys of a flute or of any other woodwind. A free aerophone lacks the enclosed column of air yet, "cause a series of condensations and rarefications by various means." Overview Aerophones are one of the four main classes of instruments in the original Hornbostel–Sachs system of musical instrument classification, which further classifies aerophones by whether or not the vibrating air is contained within the instrument. The first class (41) includes instruments which, when played, do ''not'' contain the vibrating air. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Easter Island
Easter Island (, ; , ) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is renowned for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts differ on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, a 2007 study provided compelling evidence suggesting their arrival was closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. Land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforestation. By the time of European arrival in 1722, the i ...

Rain
Rain is a form of precipitation where water drop (liquid), droplets that have condensation, condensed from Water vapor#In Earth's atmosphere, atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectricity, hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convection, convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and ...

Deity
A deity or god is a supernatural being considered to be sacred and worthy of worship due to having authority over some aspect of the universe and/or life. The ''Oxford Dictionary of English'' defines ''deity'' as a God (male deity), god or goddess, or anything revered as divine. C. Scott Littleton defines a deity as "a being with powers greater than those of ordinary humans, but who interacts with humans, positively or negatively, in ways that carry humans to new Higher consciousness, levels of consciousness, beyond the grounded preoccupations of ordinary life". Religions can be categorized by how many deities they worship. Monotheism, Monotheistic religions accept only one deity (predominantly referred to as "God"), whereas Polytheism, polytheistic religions accept multiple deities. Henotheism, Henotheistic religions accept one God, supreme deity without denying other deities, considering them as aspects of the same divine principle. Nontheistic religions deny any supreme eter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
