Entasis
In architecture, entasis is the application of a convex curve to a surface for aesthetic purposes. Its best-known use is in certain orders of Classical columns that curve slightly as their diameter is decreased from the bottom upward. It also may serve an engineering function regarding strength. Etymology The word we apply to the design principle is used by the Roman architectural historian Vitruvius, and derives from the Greek word έντείνω (''enteino''), "to stretch or strain tight". Creating the illusion of greater strength or perception of height may have been an objective in the application of entasis. Examples Examples of this design principle may be found in cultures throughout the world, from ancient times to contemporary architecture. The first use of entasis is probably in the Later Temple of Aphaia at Aigina, in the 490s B.C. It also may be observed among Classical period Greek column designs, for example, in the Doric order temples in Segesta, Selinus, Agrig ...

Architecture Of Ancient Greece
Ancient Greek architecture came from the Greek-speaking people (''Hellenic'' people) whose culture flourished on the Greek mainland, the Peloponnese, the Aegean Islands, and in colonies in Anatolia and Italy for a period from about 900 BC until the 1st century AD, with the earliest remaining architectural works dating from around 600 BC. Ancient Greek architecture is best known from its temples, many of which are found throughout the region, with the Parthenon regarded, now as in ancient times, as the prime example. Most remains are very incomplete ruins, but a number survive substantially intact, mostly outside modern Greece. The second important type of building that survives all over the Hellenic world is the open-air theatre, with the earliest dating from around 525–480 BC. Other architectural forms that are still in evidence are the processional gateway (''propylon''), the public square (''agora'') surrounded by storied colonnade (''stoa''), the town council building ...

Selinus
Selinunte (; grc, Σελῑνοῦς, Selīnoûs ; la, Selīnūs , ; scn, Silinunti ) was a rich and extensive ancient Greek city on the south-western coast of Sicily in Italy. It was situated between the valleys of the Cottone and Modione rivers. It now lies in the ''comune'' Castelvetrano, between the '' frazioni'' of Triscina di Selinunte in the west and Marinella di Selinunte in the east. The archaeological site contains many great temples, the earliest dating from 550 BC, with five centred on an acropolis. At its peak before 409 BC the city may have had 30,000 inhabitants, excluding slaves. It was destroyed and abandoned in 250 BC and never reoccupied. History Selinunte was one of the most important of the Greek colonies in Sicily, situated on the southwest coast of that island, at the mouth of the small river of the same name, and 6.5 km west of the Hypsas river (the modern Belice). It was founded, according to the historian Thucydides, by a colon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paestum
Paestum ( , , ) was a major ancient Greek city on the coast of the Tyrrhenian Sea in Magna Graecia (southern Italy). The ruins of Paestum are famous for their three ancient Greek temples in the Doric order, dating from about 550 to 450 BC, which are in an excellent state of preservation. The city walls and amphitheatre are largely intact, and the bottom of the walls of many other structures remain, as well as paved roads. The site is open to the public, and there is a modern national museum within it, which also contains the finds from the associated Greek site of Foce del Sele. Solinus wrote that it was established by Dorians. After its foundation by Greek colonists under the name of Poseidonia ( grc, Ποσειδωνία), it was eventually conquered by the local Lucanians and later the Romans. The Lucanians renamed it to Paistos and the Romans gave the city its current name. As Pesto or Paestum, the town became a bishopric (now only titular), but it was abandoned in the E ...

Column
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression (physical), compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a Capital (architecture), capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a ''Post (structural), post''. Supports with a rectangular or other non-round section are usually called ''pier (architecture), piers''. For the purpose of wind engineering, wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support Beam (structure), beams or arches on which the upper parts of walls or ceilings res ...

Doric Order
The Doric order was one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above. The Greek Doric column was fluted or smooth-surfaced, and had no base, dropping straight into the stylobate or platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Above a plain architrave, the complexity comes in the frieze, where the two features originally unique to the Doric, the triglyph and gutta, are skeuomorphic memories of the beams and retaining pegs of the wooden constructions that preceded ...

Tibet
Tibet (; ''Böd''; ) is a region in East Asia, covering much of the Tibetan Plateau and spanning about . It is the traditional homeland of the Tibetan people. Also resident on the plateau are some other ethnic groups such as Monpa, Tamang, Qiang, Sherpa and Lhoba peoples and now also considerable numbers of Han Chinese and Hui settlers. Since 1951, the entire plateau has been under the administration of the People's Republic of China, a major portion in the Tibet Autonomous Region, and other portions in the Qinghai and Sichuan provinces. Tibet is the highest region on Earth, with an average elevation of . Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth's highest mountain, rising 8,848.86 m (29,032 ft) above sea level. The Tibetan Empire emerged in the 7th century. At its height in the 9th century, the Tibetan Empire extended far beyond the Tibetan Plateau, from Central Asian's Tarim Basin and the Pamirs in the west to Yunnan ...

Hero Of Alexandria
Hero of Alexandria (; grc-gre, Ἥρων ὁ Ἀλεξανδρεύς, ''Heron ho Alexandreus'', also known as Heron of Alexandria ; 60 AD) was a Greek mathematician and engineer who was active in his native city of Alexandria, Roman Egypt. He is often considered the greatest experimenter of antiquity and his work is representative of the Hellenistic scientific tradition. Hero published a well-recognized description of a steam-powered device called an '' aeolipile'' (sometimes called a "Hero engine"). Among his most famous inventions was a windwheel, constituting the earliest instance of wind harnessing on land. He is said to have been a follower of the atomists. In his work ''Mechanics'', he described pantographs. Some of his ideas were derived from the works of Ctesibius. In mathematics he is mostly remembered for Heron's formula, a way to calculate the area of a triangle using only the lengths of its sides. Much of Hero's original writings and designs have been lost, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
