Anta De Adrenunes
The Anta de Adrenunes, located on top of a hill at 426 metres above sea level, in the municipality of Sintra, within Sintra-Cascais Natural Park, Lisbon District, Portugal, is believed to be a Stone Age dolmen, burial chamber or megalithic monument. It is a structure consisting of a cluster of granite stones, between which there is a gallery about 5 metres high that is surmounted by monoliths that rest horizontally on vertical stones. The passage is thought to have served as a collective necropolis or dolmen during the megalithic period although no artifacts or burial chambers have been found to prove this. The site contains a Geodesics on an ellipsoid, geodesic landmark that has been inserted into one of the upper stones. Initial excavations by Joaquim Possidónio Narciso da Silva (1806-1896) found no evidence of funerary use. However, Da Silva presented the results of his research at one of the sessions of the International Union for Prehistoric and Protohistoric Sciences, Intern ...

Geodesics On An Ellipsoid
The study of geodesics on an ellipsoid arose in connection with geodesy specifically with the solution of triangulation networks. The figure of the Earth is well approximated by an ''oblate ellipsoid'', a slightly flattened sphere. A ''geodesic'' is the shortest path between two points on a curved surface, analogous to a straight line on a plane surface. The solution of a triangulation network on an ellipsoid is therefore a set of exercises in spheroidal trigonometry . If the Earth is treated as a sphere, the geodesics are great circles (all of which are closed) and the problems reduce to ones in spherical trigonometry. However, showed that the effect of the rotation of the Earth results in its resembling a slightly oblate ellipsoid: in this case, the equator and the meridians are the only simple closed geodesics. Furthermore, the shortest path between two points on the equator does not necessarily run along the equator. Finally, if the ellipsoid is further perturbed to ...

Prehistoric Sites In Portugal
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalithic Monuments In Portugal
A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 in Europe alone, located widely from Sweden to the Mediterranean sea. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "mega" for great and " lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic period and into the Bronze Age. At that time, the beliefs that developed were dynamism and animism, because Indonesia experienced the megalithic age or the great stone age in 2100 to 4000 BC. So that humans ancient tribe worship certain objects that are considered to have supernatural powers. Some relics of the megalithic era are menhirs (stone monuments) and dolmens (stone tables).

Equinox
A solar equinox is a moment in time when the Sun crosses the Earth's equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise "due east" and set "due west". This occurs twice each year, around 20 March and 23 September. More precisely, an equinox is traditionally defined as the time when the plane of Earth's equator passes through the geometric center of the Sun's disk. Equivalently, this is the moment when Earth's rotation axis is directly perpendicular to the Sun-Earth line, tilting neither toward nor away from the Sun. In modern times, since the Moon (and to a lesser extent the planets) causes Earth's orbit to vary slightly from a perfect ellipse, the equinox is officially defined by the Sun's more regular ecliptic longitude rather than by its declination. The instants of the equinoxes are currently defined to be when the apparent geocentric longitude of the Sun is 0° a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solstice
A solstice is an event that occurs when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. Two solstices occur annually, around June 21 and December 21. In many countries, the seasons of the year are determined by the solstices and the equinoxes. The term ''solstice'' can also be used in a broader sense, as the day when this occurs. The day of a solstice in either hemisphere has either the most sunlight of the year ( summer solstice) or the least sunlight of the year (winter solstice) for any place other than the Equator. Alternative terms, with no ambiguity as to which hemisphere is the context, are " June solstice" and " December solstice", referring to the months in which they take place every year. The word ''solstice'' is derived from the Latin ''sol'' ("sun") and ''sistere'' ("to stand still"), because at the solstices, the Sun's declination appears to "stand still"; that is, the seasonal move ...

International Union For Prehistoric And Protohistoric Sciences
The International Union for Prehistoric and Protohistoric Sciences (IUPPS) is a learned society, linked through the International Council for Philosophy and Humanistic Studies to UNESCO, and concerned with the study of prehistory and protohistory.

Necropolis
A necropolis (plural necropolises, necropoles, necropoleis, necropoli) is a large, designed cemetery with elaborate tomb monuments. The name stems from the Ancient Greek ''nekropolis'', literally meaning "city of the dead". The term usually implies a separate burial site at a distance from a city, as opposed to tombs within cities, which were common in various places and periods of history. They are different from grave fields, which did not have structures or markers above the ground. While the word is most commonly used for ancient sites, the name was revived in the early 19th century and applied to planned city cemeteries, such as the Glasgow Necropolis. Necropoli in the ancient world Egypt Ancient Egypt is noted for multiple necropoleis. Ancient Egyptian funerary practices and beliefs about the afterlife led to the construction of several extensive necropoleis to secure and provision the dead in the hereafter. These necropoleis are therefore major archaeological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monolith
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. For instance, Savandurga mountain is a monolith mountain in India. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano. In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces. The word derives, via the Latin , from the Ancient Greek word (), from () meaning "one" or "single" and () meaning "stone".
