Crenellation
A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e., a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed " crenels" (also known as ''carnels'', or ''embrasures''), and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation. The function of battlements in war is to protect the defenders by giving them something to hide behind, from which they can pop out to launch their own missiles. A defensive building might be designed and built with battlements, or a manor house might be fortified by adding battlements, where no parapet previously existed, or cutting crenellations into its existing parapet wall.

Battlement (PSF)
A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e., a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed "Embrasure, crenels" (also known as ''carnels'', or ''embrasures''), and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation.

Crenation
Crenation (from modern Latin ''crenatus'' meaning "scalloped or notched", from popular Latin ''crena'' meaning "notch") in botany and zoology, describes an object's shape, especially a leaf or shell, as being round-toothed or having a scalloped edge. The descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis. In a hypertonic environment, the cell has a lower concentration of solutes than the surrounding extracellular fluid, and water diffuses out of the cell by osmosis, causing the cytoplasm to decrease in volume. As a result, the cell shrinks and the cell membrane develops abnormal notchings. Pickling cucumbers and salt-curing of meat are two practical applications of crenation. Plasmolysis is the term which describes plant cells when the cytoplasm shrinks from the cell wall in a hypertonic environment. In plasmolysis ...

Castle
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word ''castle'', but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; from a ''pleasance'' which was a walled-in residence for nobility, but not adequately fortified; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Use of the term has varied over time and has also been applied to structures such as hill forts and 19th-20th century homes built to resemble castles. Over the approximately 900 years when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were ...

Bas Relief
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires a lot of chiselling away of the background, which takes a long time. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs a ...

Assyria
Assyria (Neo-Assyrian cuneiform: , romanized: ''māt Aššur''; syc, ܐܬܘܪ, ʾāthor) was a major ancient Mesopotamian civilization which existed as a city-state at times controlling regional territories in the indigenous lands of the Assyrians from the 21st century BC to the 14th century BC, then to a territorial state, and eventually an empire from the 14th century BC to the 7th century BC. Spanning from the early Bronze Age to the late Iron Age, modern historians typically divide ancient Assyrian history into the Early Assyrian ( 2600–2025 BC), Old Assyrian ( 2025–1364 BC), Middle Assyrian ( 1363–912 BC), Neo-Assyrian (911–609 BC) and post-imperial (609 BC– AD 630) periods, based on political events and gradual changes in language. Assur, the first Assyrian capital, was founded 2600 BC but there is no evidence yet discovered that the city was independent until the collapse of the Third Dynasty of Ur in the 21st century BC, when a line of independent kin ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ...

Buhen
Buhen ( grc, Βοὥν ''Bohón'') was an ancient Egyptian settlement situated on the West bank of the Nile below (to the North of) the Second Cataract in what is now Northern State, Sudan. It is now submerged in Lake Nasser, Sudan; as a result of the International Campaign to Save the Monuments of Nubia, many of its antiquities were moved to the National Museum of Sudan in Khartoum. On the East bank, across the river, there was another ancient settlement, where the town of Wadi Halfa now stands. The earliest mention of Buhen comes from stelae dating to the reign of Senusret I. Buhen is also the earliest known Egyptian settlement in the land of Nubia. Old Kingdom In the Old Kingdom (about 2686–2181 BCE), there was an Egyptian colonial town at Buhen, that was also used for copper working. This was surrounded by a massive though crude stone wall. And further evidence point to the colony having been supplied from the north. The settlement may have been established during ...

Machicolation
A machicolation (french: mâchicoulis) is a floor opening between the supporting corbels of a battlement, through which stones or other material, such as boiling water, hot sand, quicklime or boiling cooking oil, could be dropped on attackers at the base of a defensive wall. A smaller version found on smaller structures is called a box-machicolation. Terminology The structures are thought to have originated as Crusader imitations of mashrabiya. The word derives from the Old French word ''machecol'', mentioned in Medieval Latin as ''machecollum'', probably from Old French ''machier'' 'crush', 'wound' and ''col'' 'neck'. ''Machicolate'' is only recorded in the 18th century in English, but a verb ''machicollāre'' is attested in Anglo-Latin. Both the Spanish and Portuguese words denoting this structure (''matacán'' and ''mata-cães'', respectively), are similarly composed from "matar canes" meaning roughly "killing dogs", the latter word being a slur referring to infidels.Vil ...

Corbel
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England. The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or parapet, has been used since Neolithic (New Stone Age) times. It is common in medieval architecture and in the Scottish baronial style as well as in the vocabulary of classical architecture, such as the modillions of a Corinthian cornice. The corbel arch and corbel vault use the technique systematically to make openings in walls and to form ceilings. These are found in the early architecture of most cultures, from Eurasia to Pre-Columbian architecture. A console is more specifically an "S"-shaped scroll bracket in the classic ...

Mark (money)
The mark was a currency or unit of account in many states. It is named for the mark unit of weight. The word ''mark'' comes from a merging of three Teutonic/ Germanic words, Latinised in 9th-century post-classical Latin as ', ', ' or '. It was a measure of weight mainly for gold and silver, commonly used throughout Europe and often equivalent to . Considerable variations, however, occurred throughout the Middle Ages. As of 2022, the only circulating currency named "mark" is the Bosnia and Herzegovina convertible mark.
