Ancient Greek architecture

Geography The mainland and islands of Greece are very rocky, with deeply indented coastline, and rugged mountain ranges with few substantial forests. The most freely available building material is stone. Limestone was readily available and easily worked. There is an abundance of high quality white marble both on the mainland and islands, particularly Paros and Naxos. This finely grained material was a major contributing factor to precision of detail, both architectural and sculptural, that adorned ancient Greek architecture. Deposits of high-quality potter's clay were found throughout Greece and the Islands, with major deposits near Athens. It was used not only for pottery vessels but also roof tiles and architectural decoration. The climate of Greece is maritime, with both the coldness of winter and the heat of summer tempered by sea breezes. This led to a lifestyle where many activities took place outdoors. Hence temples were placed on hilltops, their exteriors designed as a visual focus of gatherings and processions, while theatres were often an enhancement of a naturally occurring sloping site where people could sit, rather than a containing structure. Colonnades encircling buildings, or surrounding courtyards provided shelter from the sun and from sudden winter storms. Before the Hellenic era, two major cultures had dominated the region: the Minoan (), and the Mycenaean (c. 1500–1100 BC). Minoan is the name given by modern historians to the culture of the people of ancient Crete, known for its elaborate and richly decorated Minoan palaces, and for its pottery, the most famous of which painted with floral and motifs of sea life. The Mycenaean culture, which flourished on the Peloponnesus, was different in character. Its people built citadels, fortifications and tombs, and decorated their pottery with bands of marching soldiers rather than octopus and seaweed. Both these civilizations came to an end around 1100 BC, that of Crete possibly because of volcanic devastation, and that of Mycenae because of an invasion by the Dorian people who lived on the Greek mainland. Following these events, there was a period from which only a village level of culture seems to have existed. This period is thus often referred to as the Greek Dark Age. Art The art of the Hellenic era is generally subdivided into four periods: the Protogeometric (1100–900 BC), the Geometric (900–700 BC), the Archaic (700–500 BC) and the Classical (500–323 BC) with sculpture being further divided into Severe Classical, High Classical and Late Classical. The first signs of the particular artistic character that defines ancient Greek architecture are to be seen in the pottery of the Dorian Greeks from the 10th century BC. Already at this period it is created with a sense of proportion, symmetry and balance not apparent in similar pottery from Crete and Mycenae. The decoration is precisely geometric, and ordered neatly into zones on defined areas of each vessel. These qualities were to manifest themselves not only through a millennium of Greek pottery making, but also in the architecture that was to emerge in the 6th century. The major development that occurred was in the growing use of the human figure as the major decorative motif, and the increasing surety with which humanity, its mythology, activities and passions were depicted. This development had a direct effect on the sculptural decoration of temples, as many of the greatest extant works of ancient Greek sculpture once adorned temples, and many of the largest recorded statues of the age, such as the lost chryselephantine statues of Zeus at the Temple of Zeus at Olympia and Athena at the Parthenon, Athens, both over 40 feet high, were once housed in them. Religion and philosophy The religion of ancient Greece was a form of nature worship that grew out of the beliefs of earlier cultures. However, unlike earlier cultures, man was no longer perceived as being threatened by nature, but as its sublime product. The ancient Greeks perceived order in the universe, and in turn, applied order and reason to their creations. Their humanist philosophy put mankind at the centre of things and promoted well-ordered societies and the development of democracy. At the same time, the respect for human intellect demanded a reason, and promoted a passion for enquiry, logic, challenge, and problem-solving. The architecture of the ancient Greeks, and in particular, temple architecture, responds to these challenges with a passion for beauty, and for order and symmetry which is the product of a continual search for perfection, rather than a simple application of a set of working rules. == Architectural character ==

Early development There is a clear division between the architecture of the preceding Mycenaean and Minoan cultures and that of the ancient Greeks, with much of the techniques and an understanding of their style being lost when these civilisations fell. The Minoan architecture of Crete was of the trabeated form like that of ancient Greece. It employed wooden columns with capitals, but the wooden columns were of a very different form to Doric columns, being narrow at the base and splaying upward. City houses were built with adjoining walls and were divided into small blocks by narrow streets. Shops were sometimes located in the rooms towards the street. City houses were inward-facing, with major openings looking onto the central courtyard, rather than the street. Public buildings The rectangular temple is the most common and best-known form of Greek public architecture. This rectilinear structure borrows from the Late Helladic, Mycenaean megaron, which contained a central throne room, vestibule, and porch. The temple did not serve the same function as a modern church, since the altar stood under the open sky in the temenos or sacred precinct, often directly before the temple. Temples served as the location of a cult image and as a storage place or strong room for the treasury associated with the cult of the god in question, and as a place for devotees of the god to leave their votive offerings, such as statues, helmets and weapons. Some Greek temples appear to have been oriented astronomically. The temple was generally part of a religious precinct known as the acropolis. According to Aristotle, "the site should be a spot seen far and wide, which gives good elevation to virtue and towers over the neighbourhood". During the late 5th and 4th centuries BC, town planning became an important consideration of Greek builders, with towns such as Paestum and Priene being laid out with a regular grid of paved streets and an agora or central market place surrounded by a colonnade or stoa. The completely restored Stoa of Attalos can be seen in Athens. Towns were also equipped with a public fountain where water could be collected for household use. The development of regular town plans is associated with Hippodamus of Miletus, a pupil of Pythagoras. Public buildings became "dignified and gracious structures", and were sited so that they related to each other architecturally. The propylon or porch, formed the entrance to temple sanctuaries and other significant sites with the best-surviving example being the Propylaea on the Acropolis of Athens. The bouleuterion was a large public building with a hypostyle hall that served as a court house and as a meeting place for the town council (boule). Remnants of bouleuterion survive at Athens, Olympia and Miletus, the latter having held up to 1,200 people. Every Greek town had an open-air theatre. These were used for both public meetings as well as dramatic performances. The theatre was usually set in a hillside outside the town, and had rows of tiered seating set in a semicircle around the central performance area, the orchestra. Behind the orchestra was a low building called the skênê, which served as a store-room, a dressing room, and also as a backdrop to the action taking place in the orchestra. A number of Greek theatres survive almost intact, the best known being at Epidaurus by the architect Polykleitos the Younger. Greek towns of substantial size also had a palaestra or a gymnasium, the social centre for male citizens which included spectator areas, baths, toilets and club rooms. Structure Post and lintel , 2.

Stylobate The architecture of ancient Greece is of a trabeated or "post and lintel" form, i.e. it is composed of upright beams (posts) supporting horizontal beams (lintels). Although the existent buildings of the era are constructed in stone, it is clear that the origin of the style lies in simple wooden structures, with vertical posts supporting beams which carried a ridged roof. The posts and beams divided the walls into regular compartments which could be left as openings, or filled with sun dried bricks, lathes or straw and covered with clay daub or plaster. Alternately, the spaces might be filled with rubble. It is likely that many early houses and temples were constructed with an open porch or "pronaos" above which rose a low pitched gable or pediment. A few of these temples are very large, with several, such as the Temple of Zeus Olympus and the Olympians at Athens being well over 300 feet in length, but most were less than half this size. It appears that some of the large temples began as wooden constructions in which the columns were replaced piecemeal as stone became available. This, at least was the interpretation of the historian Pausanias looking at the Temple of Hera at Olympia in the 2nd century AD. Door and window openings narrowed towards the top. Roof The widest span of a temple roof was across the cella, or inner chamber. In a large building, this space contains columns to support the roof, the architectural form being known as hypostyle. It appears that, although the architecture of ancient Greece was initially of wooden construction, the early builders did not have the concept of the diagonal truss as a stabilising member. This is evidenced by the nature of temple construction in the 6th century BC, where the rows of columns supporting the roof of the cella rise higher than the outer walls, unnecessary if roof trusses are employed as an integral part of the wooden roof. The indication is that initially all the rafters were supported directly by the entablature, walls and hypostyle, rather than on a trussed wooden frame, which came into use in Greek architecture only in the 3rd century BC. Only stone walls, which were replacing the earlier mudbrick and wood walls, were strong enough to support the weight of a tiled roof. The earliest finds of roof tiles of the Archaic period in Greece are documented from a very restricted area around Corinth, where fired tiles began to replace thatched roofs at the temples of Apollo and Poseidon between 700 and 650 BC. Spreading rapidly, roof tiles were within fifty years in evidence for a large number of sites around the Eastern Mediterranean, including Mainland Greece, Western Asia Minor, Southern and Central Italy. The smallest temples are less than 25 metres (approx. 75 feet) in length, or in the case of the circular tholos, in diameter. The great majority of temples are between 30 and 60 metres (approx. 100–200 feet) in length. A small group of Doric temples, including the Parthenon, are between 60 and 80 metres (approx. 200–260 feet) in length. The largest temples, mainly Ionic and Corinthian, but including the Doric Temple of the Olympian Zeus, Agrigento, were between 90 and 120 metres (approx. 300–390 feet) in length. The temple rises from a stepped base or stylobate, which elevates the structure above the ground on which it stands. Early examples, such as the Temple of Zeus at Olympus, have two steps, but the majority, like the Parthenon, have three, with the exceptional example of the Temple of Apollo at Didyma having six. The core of the building is a masonry-built "naos" within which is a cella, a windowless room originally housing the statue of the god. The cella generally has a porch or "pronaos" before it, and perhaps a second chamber or "antenaos" serving as a treasury or repository for trophies and gifts. The chambers were lit by a single large doorway, fitted with a wrought iron grill. Some rooms appear to have been illuminated by skylights. : \frac 1 \varphi = \varphi - 1;\; \varphi = \frac{1 + \sqrt{5}}{2} \approx 1.618 The ancient Greek architects took a philosophic approach to the rules and proportions. The determining factor in the mathematics of any notable work of architecture was its ultimate appearance. The architects calculated for perspective, for the optical illusions that make edges of objects appear concave and for the fact that columns that are viewed against the sky look different from those adjacent that are viewed against a shadowed wall. Because of these factors, the architects adjusted the plans so that the major lines of any significant building are rarely straight. == Style ==

Orders Ancient Greek architecture of the most formal type, for temples and other public buildings, is divided stylistically into three Classical orders, first described by the Roman architectural writer Vitruvius. These are: the Doric order, the Ionic order, and the Corinthian order, the names reflecting their regional origins within the Greek world. While the three orders are most easily recognizable by their capitals, they also governed the form, proportions, details and relationships of the columns, entablature, pediment, and the stylobate. The Doric entablature is in three parts, the architrave, the frieze and the cornice. The architrave is composed of the stone lintels which span the space between the columns, with a joint occurring above the centre of each abacus. On this rests the frieze, one of the major areas of sculptural decoration. The frieze is divided into triglyphs and metopes, the triglyphs, as stated elsewhere in this article, are a reminder of the timber history of the architectural style. Each triglyph has three vertical grooves, similar to the columnar fluting, and below them, seemingly connected, are guttae, small strips that appear to connect the triglyphs to the architrave below. The famous sculptor Phidias fills the space at the Parthenon (448–432 BC) with a complex array of draped and undraped figures of deities, who appear in attitudes of sublime relaxation and elegance. Ionic order The Ionic order is recognized by its voluted capital, in which a curved echinus of similar shape to that of the Doric order, but decorated with stylised ornament, is surmounted by a horizontal band that scrolls under to either side, forming spirals or volutes similar to those of the nautilus shell or ram's horn. In plan, the capital is rectangular. It is designed to be viewed frontally but the capitals at the corners of buildings are modified with an additional scroll so as to appear regular on two adjoining faces. In the Hellenistic period, four-fronted Ionic capitals became common. Like the Doric order, the Ionic order retains signs of having its origins in wooden architecture. The horizontal spread of a flat timber plate across the top of a column is a common device in wooden construction, giving a thin upright a wider area on which to bear the lintel, while at the same time reinforcing the load-bearing strength of the lintel itself. Likewise, the columns always have bases, a necessity in wooden architecture to spread the load and protect the base of a comparatively thin upright. Corinthian order The Corinthian order does not have its origin in wooden architecture. It grew directly out of the Ionic in the mid 5th century BC, and was initially of much the same style and proportion, but distinguished by its more ornate capitals. The capital was very much deeper than either the Doric or the Ionic capital, being shaped like a large krater, a bell-shaped mixing bowl, and being ornamented with a double row of acanthus leaves above which rose voluted tendrils, supporting the corners of the abacus, which, no longer perfectly square, splayed above them. According to Vitruvius, the capital was invented by a bronze founder, Callimachus of Corinth, who took his inspiration from a basket of offerings that had been placed on a grave, with a flat tile on top to protect the goods. The basket had been placed on the root of an acanthus plant which had grown up around it. Ionic cornices were often set with a row of lion's masks, with open mouths that ejected rainwater. Architectural sculpture of the western pediment from the Artemis Temple of Corfu, Archaeological Museum of Corfu. Architectural sculpture showed a development from early Archaic examples through Severe Classical, High Classical, Late Classical and Hellenistic. A metope from a temple known as "Temple C" at Selinus, Sicily, shows, in a better preserved state, Perseus slaying the Gorgon Medusa. Both images parallel the stylised depiction of the Gorgons on the black figure name vase decorated by the Nessos painter (c. 600 BC), with the face and shoulders turned frontally, and the legs in a running or kneeling position. At this date, images of terrifying monsters have predominance over the emphasis on the human figure that developed with Humanist philosophy. The Severe Classical Style (500–450 BC) is represented by the pedimental sculptures of the Temple of Zeus at Olympia (470–456 BC). The eastern pediment shows a moment of stillness and "impending drama" before the beginning of a chariot race, the figures of Zeus and the competitors being severe and idealised representations of the human form. . The reliefs and three-dimensional sculpture which adorned the frieze and pediments, respectively, of the Parthenon, are the lifelike products of the High Classical style (450–400 BC) and were created under the direction of the sculptor Phidias. The pedimental sculpture represents the Gods of Olympus, while the frieze shows the Panathenaic procession and ceremonial events that took place every four years to honour the titular Goddess of Athens. The names of many famous sculptors are known from the Late Classical period (400–323 BC), including Timotheos, Praxiteles, Leochares and Skopas, but their works are known mainly from Roman copies. The acroteria were sculptured by Timotheus, except for that at the centre of the east pediment which is the work of the architect. The palmate acroteria have been replaced here with small figures, the eastern pediment being surmounted by a winged Nike, poised against the wind. == See also ==
