Heel Stone
The Heel Stone is a single large block of sarsen stone standing within the Avenue outside the entrance of the Stonehenge earthwork in Wiltshire, England. In section it is sub-rectangular, with a minimum thickness of , rising to a tapered top about high. Excavation has shown that a further is buried in the ground. It is from the centre of Stonehenge circle. It leans towards the southwest nearly 27 degrees from the vertical. The stone has an overall girth Girth may refer to: Mathematics * Girth (functional analysis), the length of the shortest centrally symmetric simple closed curve on the unit sphere of a Banach space * Girth (geometry), the perimeter of a parallel projection of a shape * Girth ... of and weighs about 35 tons.

Stonehenge Heel Stone - Panoramio (2)
Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds). Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 BC. The famous circle of large sarsen stones were placed between 2600 BC and 24 ...

Sarsen
Sarsen stones are silicification, silicified sandstone blocks found extensively across southern England on the Salisbury Plain and the Marlborough Downs in Wiltshire; in Kent; and in smaller quantities in Berkshire, Essex, Oxfordshire, Dorset, and Hampshire. Geology Sarsen stones are the post-glacial remains of a cap of Cenozoic silcrete that once covered much of southern England. This is thought to have formed during Neogene to Quaternary weathering by the silicification of Upper Paleocene Lambeth Group sediments, resulting from acid leaching. Etymology There are several potential sources for the word "sarsen." The first is that word "sarsen" is a shortening of "Saracen stone" which arose in the Wiltshire dialect. In the Middle Ages, "Saracen" was a common name for Muslims, and came by extension to be used for anything regarded as non-Christian, whether Muslim or pagan in contrast to Christianity. The second is that "sarsen" is vernacular variation of the Indo-European "sasan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wiltshire
Wiltshire (; abbreviated to Wilts) is a ceremonial county in South West England. It borders Gloucestershire to the north, Oxfordshire to the north-east, Berkshire to the east, Hampshire to the south-east, Dorset to the south, and Somerset to the west. The largest settlement is Swindon, and Trowbridge is the county town. The county has an area of and a population of 720,060. The county is mostly rural, and the centre and south-west are sparsely populated. After Swindon (183,638), the largest settlements are the city of Salisbury (41,820) and the towns of Chippenham (37,548) and Trowbridge (37,169). For local government purposes, the county comprises two unitary authority areas: Swindon and Wiltshire. Undulating chalk downlands characterize much of the county. In the east are Marlborough Downs, which contain Savernake Forest. To the south is the Vale of Pewsey, which separates the downs from Salisbury Plain in the centre of the county. The south-west is also downland, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excavation (archaeology)
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years. Excavation involves the recovery of several types of data from a site. This data includes artifacts (portable objects made or modified by humans), features (non-portable modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence of human activity through organic remains such as animal bones, pollen, or charcoal), and archaeological context (relationships among the other types of data).Kelly&Thomas (2011). ''Archaeology: down to earth'' (4th ed.). Belmont, Calif.: Wadsworth, Cengage Learning. Before excavating, the presence or absence of archaeological remains can often be suggested by, non-intrusive remote sensing, such as ground-penetrating radar. Basic inf ...

Vertical Direction
In astronomy, geography, and related sciences and contexts, a ''Direction (geometry, geography), direction'' or ''plane (geometry), plane'' passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction, plane, or surface is said to be horizontal (or ''leveled'') if it is everywhere perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system. Historical definition The word ''horizontal'' is derived from the Latin , which derives from the Greek , meaning 'separating' or 'marking a boundary'. The word ''vertical'' is derived from the late Latin ', which is from the same root as ''vertex'', meaning 'highest point' or more literally the 'turning point' such as in a whirlpool. Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book ''Perspective''. Geophysical defi ...

Girth (geometry)
In three-dimensional geometry, the girth of a geometric object, in a certain direction, is the perimeter of its parallel projection in that direction... For instance, the girth of a unit cube in a direction parallel to one of the three coordinate axes is four: it projects to a unit square, which has four as its perimeter. Surfaces of constant girth The girth of a sphere in any direction equals the circumference of its equator, or of any of its great circles. More generally, if is a surface of constant width , then every projection of is a curve of constant width, with the same width . All curves of constant width have the same perimeter, the same value as the circumference of a circle with that width (this is Barbier's theorem). Therefore, every surface of constant width is also a surface of constant girth: its girth in all directions is the same number . Hermann Minkowski proved, conversely, that every convex surface of constant girth is also a surface of constant width. Proj ...

Heelstone Ditch
Heelstone Ditch is a roughly circular feature surrounding the Heel Stone at Stonehenge. It is not known if there was an intended relationship between the ditch and the heelstone although it is likely that the stone was in place either before or at the same time as the ditch. It has steep sloping sides which end at a narrow flat base, and is approximately 4 ft (1.2m) deep and 3.5 ft (1.1m) wide. It is some 12 ft (3.7m) from base the base of the Heelstone, with a diameter of roughly 32 ft (9.7m). A broad arcing trench found in 1923 by Lt-Col William Hawley 9 ft (2.7m) wide cuts this ditch from the West, deepening towards the stone. Against the Heelstone Ditch (inside circle) is rammed chalk filled Stonehole 97, whose missing stone is known as Heelstone's twin although it is possible that the stone in Stonehole 97 was moved and is now the stone known as the Heelstone. The ditch was probably dug after the stone in Stonehole 97 was moved but possibly befor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard J
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic language">Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick (nickname), Dick", "Dickon", "Dickie (name), Dickie", "Rich (given name), Rich", "Rick (given name), Rick", "Rico (name), Rico", "Ricky (given name), Ricky", and more. Richard is a common English (the name was introduced into England by the Normans), German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Portuguese and Spanish "Ricardo" and the Italian "Riccardo" (see comprehensive variant list belo ...

William Hawley
Lieutenant colonel William Hawley (1851–1941) was a British archaeologist who undertook pioneering excavations at Stonehenge. Military career Hawley joined the Royal Engineers and was a captain of the Portsmouth division of the Royal Engineers Militia from March 1893. In late March 1902, he was seconded for active service in South Africa for the later stages of the Second Boer War, and after the end of this war he was back with his regiment from October 1902. Old Sarum Along with William Henry St John Hope and Duncan Hector Montgomerie, Hawley participated in the first major excavations of the Old Sarum hillfort between 1909 and 1915. These digs were organized by the Society of Antiquaries of London. Stonehenge Work at the Stonehenge prehistoric monument was carried out between 1919 and 1926, largely by Hawley alone, at times assisted by Robert Newall, a draughtsman from the Office of Works. The weather and the confusing stratigraphy of this site made work difficult, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
