The mysterious grinding grooves / De mystiska slipskårornaGannholm, Sören January 2020 (has links)
On the Island of Gotland, there is a phenomenon called grinding grooves, Sw. slipskåror. They occur in bedrock and boulders. About 3600 are known on the island today and having a length of less than half a meter to over one meter. Their purpose was unknown to the scientific community as well as their age. The directions of some 1250 Gotlandic grinding grooves, measured by the author shows there is a correlation to astronomical orientations. An archaeological excavation carried out by the author at a stone with grinding grooves gave some crucial results. The grinding groove phenomenon occurs in some other places in the world as well. In South-West of Sweden, there are quite many in a few places. They are, however shorter and have another appearance because they are more curvature than the Gotlandic ones. Their purpose and age are unknown as well. In France, there are many places with grinding grooves, Fr. polissoirs. Their appearance is more similar to the Gotlandic ones than those in the Swedish mainland. They are supposed to be Neolithic. In Africa and Australia, there are places with different kinds of carvings in stones. Some resemble those mentioned above, more or less. The difference between grinding grooves and other phenomena is floating. They are sometimes associated with the circular indentations called cup marks. There are different explanations, and some are supposed to be marks from creating stone tools, while the cult is the explanation to others.

The Thirteen Towers of Chankillo: Archaeoastronomy and Social Organization at the First Solar Observatory in America / Las Trece Torres de Chankillo: arqueoastronomía y organización social en el primer observatorio solar de AméricaGhezzi, Iván, Ruggles, Clive 10 April 2018 (has links)
The Thirteen Towers of Chankillo run north-south along a low ridge within a fourth century BC ceremonial complex in north coastal Perú. From evident observing points within the adjacent buildings to the west and east, they formed an artificial toothed horizon that spanned —almost exactly— the annual rising and setting arcs of the Sun. The Chankillo towers thus provide evidence of early solar horizon observations, and of the existence of sophisticated Sun cults, preceding by almost two millennia the Sun pillars of Inca Cusco. / Las Trece Torres son un conjunto de estructuras dispuestas en una hilera de orientación Norte-Sur en la cima de una colina en Chankillo, un centro ceremonial del siglo IV a.C. ubicado en la costa norte del Perú. A partir de puntos de observación evidentes en los edificios adyacentes al este y al oeste de las torres, estas estructuras conforman un horizonte artificial "dentado" que comprende, casi exactamente, el arco anual de salida y puesta del Sol. De esta manera, las Trece Torres proporcionan evidencias de la práctica de observaciones solares y un sofisticado culto solar que preceden, por casi dos milenios, a los "pilares del Sol" del Cusco inca.

The Buena Vista Astronomical Religious Tradition / La tradición religioso-astronómica en Buena VistaBenfer, Robert Alfred, Ojeda, Bernardino, Duncan, Neil A., Adkins, Larry R., Ludeña, Hugo, Vallejos, Miriam, Rojas, Víctor, Ocas, Andrés, Ventocilla, Omar, Villarreal, Gloria 10 April 2018 (has links)
A maritime, rather than agricultural, foundation for civilization has been postulated for the central coast of Perú; the model has been subsequently modified in light of new evidence to include exchange with farming communities in middle valleys. A key question is what caused the sudden appearance of sites with monumental architecture before the introduction of ceramics on the central Andean coast? Recent reports call for further refinement of this hypothesis, and here we present new evidence —the finding of very ancient calendaric temples, ushnus that were observatories in the Chillón Valley. We argue that the stimulus for intensification of production of storable foods required for continued population expansion was the climate shock of the end of the Optimum Climaticum in the third millennium BC. These observatories marked dates of great practical importance for both agriculture and marine production. Astronomer priests came to manage the architecture and representational art in the Late Preceramic Chillón Valley. These powerful priests, with their own special dwellings at the site, acquired power that would have superseded the family/ayllu dimension. The complexity of the observatories at Buena Vista is without precedent in the Americas. The power guarded by those first astronomer priests may have been precariously held; an unpredicted flood could have destroyed their credibility. In any case, the ushnus at Buena Vista show that a wide variety of astronomical instruments were developed: a sighting device, the gaze of a personified figure, and the photon capturing device of a special light chamber, as well as entryway and stairwell alignments. This astronomical tradition is exhibited in a very complex stage of development by 2000 BC, at the site of Buena Vista. / Desde hace mucho tiempo, diversos investigadores han postulado un carácter marítimo, en vez de agrícola, para los orígenes de la civilización en la costa central del Perú. Este modelo ha sido subsecuentemente modificado a la luz del hallazgo de nuevas evidencias para incluir el intercambio con comunidades agrícolas establecidas en los valles medios. Una pregunta clave en relación con este tema concierne a la causa de la súbita aparición de sitios con arquitectura monumental antes de la introducción de la cerámica en la costa central andina. Los trabajos recientes reclaman mayores refinamientos para esta hipótesis, por lo que los autores presentan aquí nuevas pruebas: el hallazgo de templos calendáricos muy antiguos, un tipo de "ushnus" que sirvieron de observatorios en el valle del Chillón. Se postula aquí que el estímulo para la intensificación de la producción de alimentos factibles de almacenaje requeridos por una población en continua expansión fue la convulsión climática ocurrida a fines del Optimum Climaticum en el tercer milenio a.C. Estos observatorios marcaron fechas de gran importancia práctica tanto para la producción agrícola como marítima. De esta manera, los sacerdotes-astrónomos pasaron a administrar la arquitectura y el arte figurativo en el valle del Chillón del Periodo Precerámico Tardío. Estos poderosos individuos, que poseían viviendas especiales en el sitio, adquirieron un poder que pudo haber reemplazado la dimensión de la familia/ayllu. La complejidad de los observatorios en Buena Vista no tiene precedentes en las Américas, pero el poder ejercido por estos primeros sacerdotes-astrónomos pudo haber sido precariamente sostenido; en ese sentido, una inundación no prevista podría haber destruido su credibilidad. En todo caso, los ushnus de este complejo muestran que se desarrolló una amplia variedad de instrumentos astronómicos: un dispositivo de observación, la mirada fija de una escultura de barro con rasgos antropomorfos, un mecanismo de captura de fotones en una cámara especial, así como el alineamiento de entradas y escaleras. El despliegue de esta tradición astronómica se da en una etapa muy compleja de desarrollo hacia 2000 a.C. en el sitio de Buena Vista.

Cosmophonia: Musical Expressions of Astronomy and CosmologyDiFalco, Elaine 08 1900 (has links)
Astronomy and music are both fundamental to cultural identity in the form of various musical styles and calendrical systems. However, since both are governed by incontrovertible laws of physics and therefore precede cultural interpretation, they are potentially useful for insight into the common ground of a shared humanity. This paper discusses three compositions inspired by different aspects of astronomy: Solstitium e Equinoctium, a site-specific composition for four voices and metal pipes involving an inclusive communal musical ritual and sonic meditation; Helios, a short symphonic work inspired by helioseismology; and Perspectives, a piece for soprano and percussion based on a logarithmic map of the universe.

A systematics for interpreting past structures with possible cosmic references in Sub-Saharan AfricaWade, Richard Peter 05 May 2009 (has links)
This thesis presents a method of identifying astronomical expressionsinherent within the spatial geography, cultural landscapes, and layouts of structures with a view to implementing the systematics in an African context. In determining astronomical codes of the southern African pre - early farmer and metalworking archaeological sites - this review deals with oral tradition, rituals, formative calendars, fertility, meteorites, eclipses, bio-diversity, sustainable agriculture, rainmaking and the general star lore. Conclusions are drawn from the hypothesis that certain structures functioned as astronomical expressions by use of monoliths and other configurations, with specific examples of how these possibilities were drawn from aspects within the Mapungubwe/Zimbabwe Cultural Complex and the preceding riverine cultural formations. / Dissertation (MSc(Applied Science))--University of Pretoria, 2009. / Architecture / unrestricted
