A henge loosely describes one of three related types of Neolithic earthwork. The essential characteristic of all three is that they feature a ring-shaped bank and ditch, with the ditch inside the bank. Because the internal ditches would have served defensive purposes poorly, henges are not considered to have been defensive constructions. The three henge types are as follows, with the figure in brackets being the approximate diameter of the central flat area:
- Henge. The word henge refers to a particular type of earthwork of the Neolithic period, typically consisting of a roughly circular or oval-shaped bank with an internal ditch surrounding a central flat area of more than 20 m (66 ft) in diameter. There is typically little if any evidence of occupation in a henge, although they may contain ritual structures such as stone circles, timber circles and coves. Henge monument is sometimes used as a synonym for henge. Henges sometimes, but by no means always, featured stone or timber circles, and circle henge is sometimes used to describe these structures. The three largest stone circles in Britain are each within a henge. Examples of henges without significant internal monuments are the three henges of Thornborough Henges. Although having given its name to the word henge, Stonehenge is atypical in that the ditch is outside the main earthwork bank.
- Hengiform monument. Like an ordinary henge, except the central flat area is between 5 and 20 m (16–66 ft) in diameter, they comprise a modest earthwork with a fairly wide outer bank. The terms mini-henge or Dorchester henge are sometimes used as synonyms for hengiform monument. An example is the Neolithic site at Wormy Hillock Henge.
- Henge enclosure. A Neolithic ring earthwork with the ditch inside the bank, with the central flat area having abundant evidence of occupation and usually being more than 300 m (980 ft) in diameter. Some true henges are as large as this, but lack evidence of domestic occupation. Super-henge or superhenge is sometimes used as a synonym for a henge enclosure. However, sometimes the term is used to indicate size alone rather than use, e.g. "Marden henge ... is the least understood of the four British 'superhenges' ".
A rondel dagger or roundel dagger is a type of stiff-bladed dagger used in Europe in the late Middle Ages, used by a variety of people from merchants to knights. It was worn at the waist and could be used as a utility tool, or worn into battle or in a jousting tournament as a side arm.
Göbekli Tepe is a Neolithic archaeological site in the Southeastern Anatolia Region of Turkey. The settlement was inhabited from c. 9500 to at least 8000 BCE, during the Pre-Pottery Neolithic. It is famous for its large circular structures that contain massive stone pillars – among the world's oldest known megaliths. Many of these pillars are decorated with anthropomorphic details, clothing, and sculptural reliefs of wild animals, providing archaeologists rare insights into prehistoric religion and the particular iconography of the period. The 15 m (50 ft) high, 8 ha (20-acre) tell is densely covered with ancient domestic structures and other small buildings, quarries, and stone-cut cisterns from the Neolithic, as well as some traces of activity from later periods.
The Goseck Circle is a Neolithic structure in Goseck in the Burgenlandkreis district in Saxony-Anhalt, Germany.
Bylany is a Danubian Neolithic archaeological site located around 65 km (40 mi) east of Prague in the Czech region of Bohemia. Excavation began in 1955 and work continues today.
A roundel is a circular disc used as a symbol. The term is used in heraldry, but also commonly used to refer to a type of national insignia used on military aircraft, generally circular in shape and usually comprising concentric rings of different colours. Other symbols also often use round shapes.
In archaeology, an enclosure is one of the most common types of archaeological site – It is any area of land separated from surrounding land by earthworks, walls or fencing. Such a simple feature is found all over the world and during almost all archaeological periods. They may be few metres across or be large enough to encompass whole cities.
The Giant's Ring is a henge monument at Ballynahatty, near Shaw's Bridge, Belfast, Northern Ireland. It was originally preserved by Viscount Dungannon. The inscribed stone tablet on the wall surrounding the site which details Viscount Dungannon's interest was carved by Belfast stonecarver Charles A Thompson about c.1919.
A rondeau is a form of medieval and Renaissance French poetry, as well as the corresponding musical chanson form. Together with the ballade and the virelai it was considered one of three formes fixes, and one of the verse forms in France most commonly set to music between the late 13th and the 15th centuries. It is structured around a fixed pattern of repetition of verse with a refrain. The rondeau is believed to have originated in dance songs involving singing of the refrain by a group alternating with the other lines by a soloist. The term "Rondeau" is used both in a wider sense, covering older styles of the form which are sometimes distinguished as the triolet and rondel, and in a narrower sense referring to a 15-line style which developed from these forms in the 15th and 16th centuries. The rondeau is unrelated to the much later instrumental dance form that shares the same name in French baroque music, which is more commonly called the rondo form in classical music.
Approximately 120–150 Neolithic earthworks enclosures are known in Central Europe. They are called Kreisgrabenanlagen in German, or alternatively as roundels. They are mostly confined to the Elbe and Danube basins, in modern-day Germany, Austria, Czech Republic, Slovakia, as well as the adjacent parts of Hungary and Poland, in a stretch of Central European land some 800 km (500 mi) across. They date to the first half of the 5th millennium BC; they are associated with the late Linear Pottery culture and its local successors, the Stroke-ornamented ware and Lengyel cultures. The best known and oldest of these Circular Enclosures is the Goseck circle, constructed c. 4900 BC.
The air forces of the United Kingdom – the Royal Navy's Fleet Air Arm, the Army's Army Air Corps and the Royal Air Force use a roundel, a circular identification mark, painted on aircraft to identify them to other aircraft and ground forces. In one form or another, it has been used on British military aircraft from 1915 to the present.
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface.
A roundel is a form of verse used in English language poetry devised by Algernon Charles Swinburne (1837–1909). It is the Anglo-Norman form corresponding to the French rondeau. It makes use of refrains, repeated according to a certain stylized pattern. A roundel consists of nine lines each having the same number of syllables, plus a refrain after the third line and after the last line. The refrain must be identical with the beginning of the first line: it may be a half-line, and rhymes with the second line. It has three stanzas and its rhyme scheme is as follows: A B A R ; B A B ; A B A R ; where R is the refrain.
Military aircraft insignia are insignia applied to military aircraft to visually identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.
Aircraft markings are symbols and annotations painted on aircraft, primarily for visual identification. Types of aircraft markings include:
Fine mosque lamps are oil lamps that typically have a large round body and a narrower neck that flares towards the top. They were often made with internal containers to be filled with oil and a wick to produce light. They were usually made of enamelled glass, often with gilding. Some were also made in Islamic pottery, though this was much less efficient for actual lighting. These lamps were normally hung by a circular metal frame and suspended by chains that went through a number of loops on the outside of the body. The circular frames continue to be used in many mosques today, but with plain or frosted glass lamps for electric lighting.
This is a listing of the nationality markings used by military aircraft of the United States, including those of the U.S. Air Force, U.S. Navy, U.S. Marine Corps, U.S. Coast Guard, U.S. Army and their predecessors. The Civil Air Patrol is also included for the World War II period because it engaged in combat operations which its July 1946 charter has since explicitly forbidden.
The simple dolmen or primeval dolmen is an early form of dolmen or megalithic tomb that occurs especially in Northern Europe. The term was defined by archaeologist, Ernst Sprockhoff, and utilised by Ewald Schuldt in publicising his excavation of 106 megalithic sites in the north German state of Mecklenburg-Vorpommern. The simple dolmen emerged in the early days of the development of megalithic monuments of the Funnelbeaker culture (TBK) and around 3,500 BC they appeared across almost the entire region covered by the stone cult structures of Nordic megalith architecture, but not in the Netherlands, in Lower Saxony west of the River Weser nor east of the River Oder and only once in Sweden.
A roundel is a circular charge in heraldry. Roundels are among the oldest charges used in coats of arms, dating from the start of the age of heraldry in Europe, circa 1200–1215. Roundels are typically a solid colour but may be charged with an item or be any of the furs used in heraldry. Roundels are similar to the annulet, which some heralds would refer to as a false roundel.
