Welsh Units Of Measurement
Welsh units of measurement are those in use in Wales between the Sub-Roman period (prior to which the Britons used Roman units) and the 13th-century Edwardian conquest (after which English units were imposed). Modern Wales no longer employs these units even for customary purposes but instead follows the custom as elsewhere in Britain of using a mixture of metric and Imperial units. Length In the Venedotian Code used in Gwynedd, the units of length were said to have been codified by Dyfnwal Moelmud but retained unchanged by Hywel Dda. The code provided for computing the units variously, as well as deriving them from grains of barley. In measuring milk and its legal worth ('), disputes over the length of the inch used in the container were to be resolved by the width of the judge's thumb. The code notes that in some areas of Wales, the rod used to compute the Welsh acre (') was not reckoned from feet but taken to be "as long as the tallest man in the ref with his hand above his hea ...

Electric Resistance Welding
Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. The electric current can be supplied to electrodes that also apply clamping pressure, or may be induced by an external magnetic field. The electric resistance welding process can be further classified by the geometry of the weld and the method of applying pressure to the joint: spot welding, seam welding, flash welding, projection welding, for example. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the metal coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, electric current and length of welding time. Small pools of molten metal are formed at the point of most electrical resista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm (unit)
The palm is an obsolete Anthropic units, anthropic units of measurement, unit of length, originally based on the width of the human palm and then variously standardized. The same name is also used for a second, rather larger unit based on the length of the human hand. The width of the palm was a traditional unit in ancient Egyptian units of measurement#Length, Ancient Egypt, ancient Hebrew units#Length, Israel, Ancient Greek units of measurement#Length, Greece, and Ancient Roman units of measurement#Length, Rome and in medieval English units of measurement, England, where it was also known as the hand,. handbreadth, or handsbreadth.. The length of the hand—originally the Ancient Roman units of measurement#Length, Roman "greater palm"—formed the palm of medieval traditional Italian units of measure#Length, Italy and Traditional French units of measurement, France.

Cantref
A cantref ( ; ; plural cantrefi or cantrefs; also rendered as ''cantred'') was a Wales in the Early Middle Ages, medieval Welsh land division, particularly important in the administration of Welsh law. Description Land in medieval Wales was divided into ''cantrefi'', which were themselves divided into smaller commote, ''cymydau'' (commotes). The word ''cantref'' is derived from ''cant'' ("a hundred") and ''tref'' ("town" in modern Welsh language, Welsh, but formerly used for much smaller settlements). The ''cantref'' is thought to be the original unit, with the commotes being a later division. ''Cantrefi'' could vary considerably in size: most were divided into two or three commotes, but the largest, the ''Cantref Mawr'' (or "Great Cantref") in Ystrad Tywi (now in Carmarthenshire) was divided into seven commotes. History The antiquity of the ''cantrefi'' is demonstrated by the fact that they often mark the boundary between Welsh language#Dialects, dialects. Some were originally k ...

Cwmwd
A commote (, sometimes spelt in older documents as , plural , less frequently )''Geiriadur Prifysgol Cymru'' (University of Wales Dictionary), p. 643 was a secular division of land in Medieval Wales. The word derives from the prefix ("together", "with") and the noun ("home, abode"). The English word "commote" is derived from the Middle Welsh . The basic unit of land was the , a small basic village or settlement. In theory, 100 made up a (literally, "one hundred settlements"; plural: ), and half or a third of a was a , although in practice the actual numbers varied greatly. Together with the , commotes were the geographical divisions through which defence and justice were organised. In charge of a commote would be a chieftain probably related to the ruling Prince of the Kingdom. His court would have been situated in a special , referred to as a . Here, the bonded villagers who farmed the chieftain's estate lived, together with the court officials and servants. Commotes were fu ...

Maenor
The maenor (pl. ''maenorau'') was a gathering of villages in medieval Wales. In North Wales the word ''maenol'' was used for a similar, but not identical, idea. Although it is very often conflated with the English manor, ''maenor'' predates that Norman French term by centuries and is apparently etymologically unrelated, instead deriving from Welsh ''maen'' ("stone")Wade-Evans, Arthur. ''Welsh Medieval Law''. Oxford Univ., 1909. Accessed 1 Feb 2013. possibly originally describing the stone homes of local lords or the area sharing a single mill. Two kinds of ''maenorau'' were distinguished: those of the nobles and free yeomen (the ''maenor wrthdir'') and those of the taeog (serfs; the ''maenor vro''). According to the Laws of Hywel Dda ''Cyfraith Hywel'' (; ''Laws of Hywel''), also known as ''Welsh law'' (), was the system of law practised in medieval Wales before its conquest of Wales by Edward I, final conquest by England. Subsequently, the Welsh law's criminal codes were s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Book Of Chirk
The ''Black Book of Chirk'' () is a 13th-century Welsh-language manuscript, known also as the Chirk Codex. It is Peniarth 29 of the National Library of Wales, and deals with legal and historical matters. It contains also an elegy addressed at Llywelyn ap Iorwerth; king of Wales. This poem was probably written by his grandson Llywelyn ap Gruffudd who lived in the 13th century. The Black Book of Chirk was one of the collection of manuscripts amassed at the mansion of Hengwrt, near Dolgellau, Gwynedd, by Welsh antiquary Robert Vaughan (c. 1592 – 1667); the collection later passed to the newly established National Library of Wales as the Peniarth or Hengwrt-Peniarth Manuscripts. The manuscript's association with Chirk in north Wales is not known to go back beyond the 16th century. Aneurin Owen called it Manuscript A, of the "Venedotian code". John Gwenogvryn Evans John Gwenogvryn Evans (20 March 1852 – 25 March 1930) was a Welsh palaeographic Palaeography ( UK) or pal ...

Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the Comparison of the imperial and US customary measurement systems, related but differing system of United States customary units, customary units of the United States. The imperial units replaced the Winchester measure, Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had metrication, officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empi ...

Aneurin Owen (antiquarian)
Aneurin Owen (23 July 1792 – 17 July 1851) was a Welsh historical scholar. Life Aneurin Owen was a son of William Owen by his wife, Sarah Elizabeth. While he was still a child his father took the additional name of Pughe on inheriting some property at Nantglyn in Denbighshire. The family moved there from London. Owen was for a short time at Friars School, Bangor, but was mainly educated by his father. Aneurin made his home at Tanygyrt, near Nantglyn, and in 1820 married Jane Lloyd, also of Nantglyn. With the passing of the Tithe Commutation Act 1836, he was appointed one of the assistant tithe commissioners for England and Wales.
