Trelystan Church, Montgomeryshire 08
Trelystan is a remote parish and township on the border of the historic county of Montgomeryshire with Shropshire. Trelystan now forms part of the community of Forden, Leighton and Trelystan in Powys. Trelystan was a chapel of ease within the parish of Worthen and it also served the township of Leighton. In some old sources the parish is also referred to as Wolston Mynd. History Elystan Glodrydd, who died in 1010AD, was possibly buried at Trelystan, as the Welsh placename could derive from ''Cappell Tref Elistan''. This is first mentioned in the Harleian Manuscript 1973, written by Jacob Chaloner: In 1485, Long Mountain by Trelystan was the muster point of the Welsh army of Henry Tudor, led by military commander Sir Rhys ap Thomas. They marched from there to Bosworth Field, where they defeated King Richard III. Sir Rhys’ wife Efa (English: ‘Eva’) was a direct descendant of Elystan via his grandson Idnerth ap Cadwgan ab Elystan. In 1854 Leighton became a separa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architecture
Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements. The practice, which began in the prehistoric era, has been used as a way of expressing culture for civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century AD treatise '' De architectura'' by the Roman architect Vitruvius, according to whom a good building embodies , and (durability, utility, and beauty). ...

Rafter
A rafter is one of a series of sloped structural members such as wooden beams that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof shingles, roof deck and its associated loads. A pair of rafters is called a ''couple''. In home construction, rafters are normally made of wood. Exposed rafters are a feature of some traditional roof styles. Applications In recent buildings there is a preference for trussed rafters on the grounds of cost, economy of materials, off-site manufacture, and ease of construction, as well as design considerations including span limitations and roof loads (weight from above). Types in traditional timber framing There are many names for rafters depending on their location, shape, or size (see below). The earliest surviving roofs in Europe are of common rafters on a tie beam; this assembly is known as a "closed couple". Later, principal rafters and common rafters were mixed, which is ...

Medieval
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the Post-classical, post-classical period of World history (field), global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern history, modern period. The medieval period is itself subdivided into the Early Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the ...

Purlin
A purlin (or historically purline, purloyne, purling, perling) is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin. Purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment. Etymology Information on the origin of the term "purlin" is scant. The Oxford Dictionary suggests a French origin, with the earliest quote using a variation of ''purlin'' in 1447, though the accuracy of this claim has been disputed. In wood construction Purlin plate A purlin plate in wood construction is also called an "arcade plate" in European English, "under purlin", and "principal purlin". The term plate means a major, horizontal, supporting timber. Purlin plates are beams which support the mid-span of rafters and are supported by posts. By supporting the rafters they allow longer spans than the rafters alone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
