Knowth Passage Tomb 5
Knowth (; ) is a prehistoric tomb overlooking the River Boyne in County Meath, Republic of Ireland, Ireland. It comprises a large passage tomb surrounded by 17 smaller tombs, built during the Neolithic Europe, Neolithic era around 3200 BC. It contains the largest assemblage of megalithic art in Europe. Knowth is part of the Brú na Bóinne complex, a World Heritage Site that also includes the similar passage tombs of Newgrange and Dowth. After its initial period of use, Knowth gradually became a ruin, although the area continued to be a site of ritual activity in the Bronze Age Ireland, Bronze Age. During the Early Medieval Ireland, early Middle Ages, a royal residence was built on top of the great mound, which became the seat of the Kings of Brega, Kings of Knowth or Northern Brega. Archaeologist George Eogan led an extensive investigation of the site from the 1960s to 1980s, and parts of the monument were reconstructed. Description The large mound has been estimated to date fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Eogan
George Eogan, MRIA (14 September 1930 – 18 November 2021) was an Irish archaeologist. He was born in Nobber, County Meath, and studied at University College Dublin (UCD) and then Trinity College Dublin. In 1965, he was appointed to a lectureship at UCD, becoming a professor in 1979, and also serving as head of department from then until 1995.''From megaliths to metal: essays in honour of George Eogan'', p.xii Eogan was particularly known for his work over forty years at Knowth, having been director of the Knowth Research Project. In 1968, he became the first person in over a millennium to enter the east-side tomb at the site. Eogan was also appointed an independent member of Seanad Éireann Seanad Éireann ( ; ; "Senate of Ireland") is the senate of the Oireachtas (the Irish legislature), which also comprises the President of Ireland and Dáil Éireann (defined as the house of representatives).

Milankovitch Cycles
Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years. The term was coined and named after the Serbian geophysicist and astronomer Milutin Milanković. In the 1920s, he provided a more definitive and quantitative analysis than James Croll's earlier hypothesis that variations in eccentricity, axial tilt, and precession combined to result in cyclical variations in the intra-annual and latitudinal distribution of solar radiation at the Earth's surface, and that this orbital forcing strongly influenced the Earth's climatic patterns. Earth movements The Earth's rotation around its axis, and revolution around the Sun, evolve over time due to gravitational interactions with other bodies in the Solar System. The variations are complex, but a few cycles are dominant. The Earth's orbit varies between nearly circular and mildly elliptical (its eccentricity varies). When the orbit is more elongated, there is more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equinox
A solar equinox is a moment in time when the Sun appears directly above the equator, rather than to its north or south. On the day of the equinox, the Sun appears to rise directly east and set directly west. This occurs twice each year, around 20 March and 23 September. An equinox is equivalently defined as the time when the plane of Earth's equator passes through the geometric center of the Sun's disk. This is also 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° and 180°. The word is derived from the Latin ', from ' (equal) and ' ( ...

Selenography
Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). Like geography and areography, selenography is a subdiscipline within the field of planetary science. Historically, the principal concern of selenographists was the mapping and naming of the lunar terrane identifying Lunar mare, maria, Impact crater, craters, mountain ranges, and other various features. This task was largely finished when high resolution images of the near side of the Moon, near and far side of the Moon, far sides of the Moon were obtained by orbiting spacecraft during the early space era. Nevertheless, some regions of the Moon remain poorly imaged (especially near the poles) and the exact locations of many features (like crater depths) are uncertain by several kilometers. Today, selenography is considered to be a subdiscipline of Geology of the Moon, selenology, which itself is most often referred to as simply "lunar science." History ...

Serpentiform
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is ...

Lozenge (shape)
A lozenge ( ; symbol: ), often referred to as a diamond, is a form of rhombus. The definition of ''lozenge'' is not strictly fixed, and the word is sometimes used simply as a synonym () for ''rhombus''. Most often, though, lozenge refers to a thin rhombus—a rhombus with two acute and two obtuse angles, especially one with acute angles of 45°. The lozenge shape is often used in parquetry (with acute angles that are 360°/''n'' with ''n'' being an integer higher than 4, because they can be used to form a set of tiles of the same shape and size, reusable to cover the plane in various geometric patterns as the result of a tiling process called tessellation in mathematics) and as decorative art, decoration on ceramics (art), ceramics, Silver (household), silverware and textiles. It also features in heraldry and Suit (cards), playing cards. Symbolism The lozenge motif dates from the Neolithic and Paleolithic art, Paleolithic period in Eastern Europe and represents a sown Field (agr ...

Spirals
In mathematics, a spiral is a curve which emanates from a point, moving further away as it revolves around the point. It is a subtype of whorled patterns, a broad group that also includes concentric objects. Two-dimensional A two-dimensional, or plane, spiral may be easily described using polar coordinates, where the radius r is a monotonic continuous function of angle \varphi: * r=r(\varphi)\; . The circle would be regarded as a degenerate case (the function not being strictly monotonic, but rather constant). In ''x-y-coordinates'' the curve has the parametric representation: * x=r(\varphi)\cos\varphi \ ,\qquad y=r(\varphi)\sin\varphi\; . Examples Some of the most important sorts of two-dimensional spirals include: * The Archimedean spiral: r=a \varphi * The hyperbolic spiral: r = a/ \varphi * Fermat's spiral: r= a\varphi^ * The lituus: r = a\varphi^ * The logarithmic spiral: r=ae^ * The Cornu spiral or ''clothoid'' * The Fibonacci spiral and golden spiral * ...

181 Knowth, Coutny Meath
Year 181 ( CLXXXI) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Burrus (or, less frequently, year 934 ''Ab urbe condita''). The denomination 181 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Imperator Lucius Aurelius Commodus and Lucius Antistius Burrus become Roman Consuls. * The Antonine Wall is overrun by the Picts in Britannia (approximate date).

Threshold Stone
A threshold stone or sill stone () is a rectangularly dressed stone slab that forms part of the entrance of megalithic tombs of the Funnelbeaker culture, normally those with a passage. The red sandstone slab, up to 0.1 metres thick, was buried in the ground to a depth of 0.2 metres at the entrance to the chamber. Cultural sites of other types, such as Domus de Janas, also have a clear partition between the passage and the ante-chamber or main chamber. Threshold stones are typical of dolmens, gallery graves and passage graves, etc. Whilst in most simple dolmens the blocking stone (''Verschlussstein'') of the entrance side was replaced by a threshold stone of varying height, the entrance to extended dolmens and great dolmens was narrowed axially or coaxially usually to about half the width of the chamber and the lower threshold stone marked the transition in the open doorway between the passage and the chamber. In simple dolmens with no passage and an entrance opening, the threshol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cremated
Cremation is a method of Disposal of human corpses, final disposition of a corpse through Combustion, burning. Cremation may serve as a funeral or post-funeral rite and as an alternative to burial. In some countries, including India, Nepal, and Syria, cremation on an Pyre, open-air pyre is an ancient tradition. Starting in the 19th century, cremation was introduced or reintroduced into other parts of the world. In modern times, cremation is commonly carried out with a Crematorium, closed furnace (cremator), at a crematorium. Cremation leaves behind an average of of remains known as ''ashes'' or ''cremains''. This is not all ash but includes unburnt fragments of bone mineral, which are commonly ground into powder. They are inorganic and inert, and thus do not constitute a health risk and may be buried, interred in a memorial site, retained by relatives or scattered in various ways. History Ancient Cremation dates from at least 17,000 years ago in the archaeological record, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
