HELLENIC ARCHITECTURE

We have noted in the previous chapter that Hellenic art, like Hellenic culture generally, was a product of the senses guided by the intellect--the expression of intellectualised sensations. To his crude sensations the artist applied very much the same process that the modern scientist has applied to crude oil, until, through experiments guided by observation and reasoning, he has developed refined oil, which gives the purest and intensest possible illumination. Thus the Hellenic artists, through generations, refined upon the forms of their architecture, to create a unity, distinguished by fitness, proportion, harmony and rhythm, until they brought it to the highest degree of expressional capacity; appealing alike to feeling and to reason. It reached its highest expression in the temple, the supreme monument of the community’s civic consciousness.

The developed form of the Hellenic Temple resembled the Egyptian in being a product of the “post and beam” principle of construction; but differed in its purpose that the outside rather than the inside should present superior dignity of design. The chief feature of the latter was the Order, as it is called in Hellenic and Roman architecture, or combination of columns and entablature. It might be confined to a portico at the entrance or supplemented by another portico in the rear, or still further extended by a colonnade that surrounded all

four sides of the _cella_ or _domos_, house of the god, in which case it is called a _peristyle_.

The emphasis of the order as a constructive and decorative feature has been traced back by some students to the Dorian people’s primitive custom of worshipping in groves. The religious ceremonies, which included a procession of the worshippers, would be conducted amid the trees surrounding the altar or shrine, and in time a roofing of cross pieces thatched with boughs may have been attached to the trees. Accordingly, those who adopt this view suggest that when the use of a grove was succeeded by a constructed temple, the original feature was the peristyle. And possibly there is a commemoration of this in the peristyle of the Parthenon, where a procession of worshippers of the goddess is represented in the sculptured frieze that embellishes the outside of the walls of the cella--thus embodying in the most highly developed form of Hellenic temple its origin in primitive religion.

The character of the form seems to have originated in wood construction, certain features of which--to be referred to later--were retained after stone or marble was employed and were translated into details of decoration. The gradual transition to materials of construction, less at the mercy of fire, is hinted at by Pausanias, a Greek geographer and writer on art of the second century B.C. , in his description of the =Heraion= or =Temple of Hera= (Juno) at =Olympia=, the oldest known example of a Doric Temple, attributed to 1000 B.C.

The cella wall, he says, was constructed of sun-dried bricks on a lower course of stonework, but the entablature was still of wood, covered with terra-cotta. One wooden column was still standing in the _opisthodomos_, but elsewhere as the wooden columns decayed they had been replaced by stone ones; the design of their capitals showing that the work of restoration lasted from the sixth century to Roman times. The roof was covered with tiles. The cella was divided into a central _nave_ and _side-aisles_ by two rows of columns for the support of the roof, and the aisles were intersected by small screen walls; thus forming alcoves, corresponding to the side-chapels of a Gothic cathedral. In one of these alcoves German explorers in 1878 discovered the _Hermes_ of Praxiteles, which is probably the only marble statue in existence that was actually wrought by the hands of one of the great sculptors.

=Early Doric Examples.=--The Dorian migration pushed down through Macedonia and Thessaly into the peninsula of Greece and spread through the islands of the Ægean as far as Crete, afterward planting colonies at =Pæstum= and other sites in Southern Italy and at =Syracuse=, =Selinus=, and =Agrigentum= in Sicily. Throughout all this wide area they carried their particular style of Order--the Doric. In developing it, they brought into play what has been judged their distinguishing trait of character--sense of proportion.

The earliest known examples of Doric temples, built originally of stone, are at =Corinth= and that of =Phœbus Apollo= on the island of =Ortygia=, at the entrance to the harbour of Syracuse. In these, which are attributed to the seventh century B.C. , the columns are monoliths with widely projecting capitals, and set so close together that the intercolumniation was less than one diameter of the column. For the early Greeks appear to have been distrustful of the bearing capacity of stone as compared with wood.

Belonging to the sixth century are the colossal =Temples= =of Zeus= at =Selinus= and =Agrigentum= and the =Temple of Poseidon= (Neptune) in =Pæstum=. In the last the columns are composed of sections or “drums,” and there are still in position in the cella the smaller columns, superimposed on the main ones for the support of the roof.

The temples of the fifth century are distinguished by increased refinement in the matter of proportion and details and by superior skill and workmanship. They include the =Temple of Athene= (Minerva) on the island of =Ægina=; the so-called =Theseum=, supposed to have been dedicated to =Heracles= (Hercules), in =Athens=; and the =Temple of Zeus= which forms one of the group of temples at =Olympia=. It is the most complete temple-group yet discovered, and was the scene of the religious ceremonies in connection with the Pan-Hellenic Games.

With the second half of the fifth century began the supremacy of Athens in the affairs of Hellas under the rule of Pericles, which enabled her as custodian of the Hellenic treasury to undertake the beautifying of the Acropolis. This culminated in the =Parthenon=, the noblest example of the Doric style and, as Mr. A. D. F. Hamlin writes, “the most faultless in design and execution of all buildings erected by man.”

Following, apparently, the tradition of worshipping in groves, the Dorians placed their temples in a _temenos_, or enclosure in which were other shrines, altars, and treasuries. Whether this temenos was on a hill-top, as in the case of the Acropolis in Athens and the site of the temple-group in =Agrigentum=, or in a valley on sloping ground as at =Delphi=, the irregularities of the ground were taken advantage of in the disposition of the buildings. Thus was created an ensemble in which art and nature united, while in the case of a level site, as at =Olympia=, =Delos=, and =Pæstum=, the temples were grouped in picturesque irregularity.

=Temple Plans.=--The nucleus of the temple plan was the _naos_, containing the statue of the deity. Adjoining it were other chambers, connected with the ritual of worship; and this aggregate of naos and chambers, enclosed within walls, is known as the _Cella_.

It was approached from the front, which faced the _east_, by a covered, columned vestibule, open at the sides, called the _pronaos_. This was often repeated at the rear under the name of _epinaos_, or, as the Romans called it, _posticum_.

The pronaos was entered through a _portico_. When the latter was composed of columns, set between the prolonged sides of the cella, the type of plan was called _in antis_.

When the side-walls were not prolonged, but terminated in pilasters, known as _antiæ_, and the supporting members of the front façade were solely columns, the type was called _prostylar_ or _prostyle_.

If, under the same conditions the portico was repeated at the rear, the type was called _amphi-prostylar_ or _amphi-prostyle_.

If the whole were surrounded by a colonnade or _peristyle_ the type was _peripteral_; while if a second row of columns were added on each side, as in the great =Temple= of the =Olympian Zeus=, erected in Athens during the Roman occupation, the type was _dipteral_. The external aisle, formed by the colonnade on each side was known as the _pteroma_.

Where there was no peristyle, but columns, known as false or engaged, were built into the wall of the cella, the type was _pseudo-peripteral_.

There are also to be mentioned the octagonal plan, as seen in the =Tower of the Winds= in =Athens=; the circular peripteral plan of the =Tholos= at =Epidauros= and the examples of irregular planning presented by the =Erechtheion= and =Propylæa=.

The type was further distinguished by the number of columns--four, six, eight, or ten--composing the portico, as, respectively, tetrastyle, hexastyle, octostyle, and decastyle.

Thus the =Parthenon= is _octostyle peripteral_; Temple of =Poseidon=, =Paestum=, hexastyle peripetral; of =Jupiter Olympios=, =Atucus=, _octostyle dipteral_; of =Apollo=, =Bassæ=, _in antis_.

=Temple Form.=--The cella, or chamber for the god, was built originally of wood; later of sunburnt bricks on a lower course of stonework, the whole being coated with a thin layer of stucco, as is found to have been the practice also in later Doric temples in Sicily and Italy, where the material was soft stone. To protect it from the damp of the ground as well as to dignify it, the cella was raised on a platform, approached by steps.

On the top of the walls was laid a framework of timber sills, crossed by transverse beams, on which stood posts to hold the ridge-piece, from which the rafters sloped to the sills, so that the roof which was of wood, covered with sunburnt brick and later by tiles, formed eaves to protect the cella from the roof-rain.

The next step to add dignity to the entrance would be to prolong the gable end in front and support it by posts, so as to form a porch or portico. At first the weight of this might be chiefly carried by an extension of the side walls. Then a superior effect of lightness and dignity would be given to the portico by omitting the support of the sides and substituting posts; while, for further embellishment, a similar portico might be extended from the rear of the cella.

Then, in the search for dignity and also to give more protection from weather to the walls of the cella, the eaves of the roof would be further prolonged outward and made to rest on sills that were supported by a series of posts. In this way the cella was completely surrounded by a colonnade or peristyle.

As the use of stone or marble was adopted, the platform became the _stylobate_, which was approached by three steps, carried along the entire length of all the sides. The cella was built of marble or stucco-covered stone, and marble or stone took the place of the sills and beams of the roof, but the latter continued to be constructed of wood, supported by small columns resting on the capitals of larger ones. The outside sheathing of the roof was of terra-cotta or marble tiles. Unlike the roof of an Egyptian temple which was raised in the centre to admit clerestory windows, that of a Hellenic temple had an uninterrupted slope. Whence then was the light derived for the interior?

=Lighting.=--Since all roofs, being of wood, have perished, the explanations that have been attempted are purely conjectural. A remark by Vitruvius, the Roman architect and author of ten books on architecture, regarding the =Temple of Zeus= at =Athens= that it was _hypæthral_ (open to the sky) has led to a suggestion that part of the roof may have been open, as in the case of the Pantheon in Rome. But, at the time he wrote, the cella was exposed because Sulla had carried off to Rome some of the supporting columns. Another Roman writer, Strabo, describes the decastyle =Temple of Apollo= near =Miletus= as hypæthral, but gives as the reason the enormous size of the cella, in which precious groves of laurel bushes grew. So, it is purely a surmise that the portion of the roof may have been omitted and that the temples were hypæthral.

Another theory, founded upon the discovery in a temple at =Bassæ= of three marble tiles, or thin slabs, pierced with holes about 18 inches by 10, is that some five of these, let into each side of the roof, would have lighted the interior amply without admitting much rain. Again, the use of marble tiles has afforded a suggestion that, Parian marble being very translucent, the light might have penetrated through. James Fergusson, on the other hand, conjectured that a trench was let into each side of the roof; but this would have needed drains to carry off the water and no sign of a system of drainage has been found in any temple. Other authorities, however, maintain that it was only through the open doorway that light was admitted, which owing to the clear atmosphere of Greece and the reflection from the marble pavement, would be sufficient.

=The Orders.=--In Hellenic architecture there are two fully developed Orders--or combinations of Columns and Entablature--the Doric and the Ionic. To these are usually added a third, the Corinthian, which, however, though invented by the Hellenic artists, did not receive its full development as an independent order until employed by the Romans. The principal members of the classic column are the _capital_, _shaft_, and, except in the Doric order where the shaft was set directly on the stylobate, the _base_.

=Doric Column.=--It is possible that the Dorians took the character of their column originally from the example of Minoan architecture. For in a fresco at Cnossos appear the façades of three temples with columns, and the representation of the latter corresponds with the facts discovered in the actual remains of the palace. The columns are of wood, and have no base, since the shaft is let into a socket in the masonry. It is crowned by a _torus_, or circular cushion with a half-round edge, on which rests a square block, the _abacus_. The shaft differs in one respect, it narrows downward; whereas all Hellenic columns taper upward. The reason assigned for the Cretan practice is that the tree-trunk was inverted so that it might retain the sap.

All these features are reproduced in stone in the columns of the doorway of the =Tomb of Atreus= at =Mycenæ=, which has been already mentioned. The shafts of these columns are decorated with _chevrons_, whereas the Greeks in their best examples never decorated the shaft, nor, in fact, any other part of the structure that carried the chief strains.

Upon this crude type the Dorian architects continually improved until they had evolved an order of the most subtle refinement. In the earlier examples the diminution upward of the shaft is more pronounced than in the Parthenon, where the diameter at the bottom is 6 feet 3 inches and at the top 4 feet 9 inches, which gives a diminution of slightly over one quarter of the lower diameter. The shaft, except in one or two temples that were not completed, was always fluted. The flutes usually numbered twenty, and were elliptic in section, meeting in a sharp edge or arris, thus differing from the flat-edged fillet that separated the flutings of the Ionic and Corinthian. In order to correct the optical illusion, suggested in a diminishing shaft, that the contours are concave, they were made slightly convex, the swell of this _entasis_, as the convex is called, being greatest at about one-third of the distance from the bottom.

As the shaft nears the capital, it is encircled by a narrow groove or _annula_. At the top of the shaft is a series of annulæ, some of which are cut in the shaft and others in the lower member of the capital, the _echinus_, so that the shaft appears to project in a necking, into which the capital is set. The _echinus_ is a circular cushion with an eccentric curve; a curve, that is to say, that is not part of a circle. (Compare by contrast the semi-circular curve of the _torus_.) Upon the echinus sets firmly the _abacus_, a square block with a side measurement the same as the diameter of the echinus.

The height of the column varied in its proportion to the lower diameter. In the =Temple of Poseidon=, at =Pæstum=, the height is four times the diameter; in the later example of the =Parthenon= nearly five and a half times, while in the =Temple of Jupiter Nemæus= it is six and a half times.

The _intercolumniation_, or space between the columns, also varies. In the older temples it was about one diameter of the column, the space between the angle columns being always less; while in the case of the Parthenon the distance varies from one diameter to 1.24; this being an instance of deviation from geometrical regularity to be referred to later.

It remains to mention the _antæ_. These were flat, right-angled columns, projecting slightly from the wall of the pronaos at the corners, facing the end columns. While they correspond to the latter, they differ in three respects. The shaft did not taper and was set on a small base, while the capital was distinguished by different mouldings. For the mouldings suitable to a free-standing column, supporting actual weight were felt to be unsuited for a member attached to a wall, whose functions were decorative.

=Doric Entablature.=--The principal members of the entablature are the _architrave_ or supporting member, the _frieze_ or decorative member, and the _cornice_ or protecting member.

The _architrave_, as its name implies, “the chief beam” of the entablature, rests immediately upon the abacus; its edge corresponding neither with that of the abacus nor with the top edge of the shaft, but so adjusted to both as to ensure a feeling of complete stability. The architrave was usually plain[1] and crowned with a projecting fillet, called the _tænia_, which beneath the _triglyphs_, is supplemented by a lower fillet, known as the _regula_. On the under side of the latter were six studs, which recall perhaps the wooden pegs with which the ends of the beams in primitive construction were fastened.

The _frieze_ is a vertical surface, composed alternately of triglyphs and metopes. The _triglyphs_, so called because they are divided into three vertical channels, represent the ends of the primitive longitudinal sills of the cella roof; and a recollection of the woodworker’s craft was still preserved in the chamfer or hollow of their outer edges. The function of the triglyphs was to support the cornice. Generally they were set above and between the columns, but at each end of the entablature one adjoins the corner, thereby increasing the effect of stability.

The space between the triglyphs, called the _metope_, was originally left open, except for a wooden shutter to keep out birds. But in the most elaborate examples of later date the metope was decorated with sculpture in high relief. Those of the Parthenon contained groups, representing fights with Centaurs, Amazons, and Trojans.

Above the frieze was the cornice, which, as a protection from the drip of the roof, projected to a distance, about one-third of the diameter of a column. Its chief members were a vertical band, known as the _corona_, and an under-part, the _soffit_. The latter sloped down under the corona at about the same angle as the slope of the roof, and was decorated above each triglyph and metope with a _mutule_ or square block, studded with eighteen _guttae_, or drops, a device that recalls the method of making fast the ends of the rafters with wooden pegs.

The cornice was carried up the two sloping edges of the roof, but here distinguished by an additional feature, the _cymatium_ or gutter. The triangle or gable thus formed by the three cornices was called the _pediment_. It was embellished at the top and ends with small pedestals, _acroteria_, on which stood figures or conventional ornaments.

In a Doric temple the corona, on the sides of the building was without a cymatium, but studded instead with _ante-fixae_, ornaments of terra-cotta or marble, placed opposite the end of each tile-ridge of the roof. The latter, as we have already noted, was covered with tiles of marble or terra-cotta, and finished at the top with ridge-tiles.

The mere reading of these details is dry enough. They should be read with an eye on the examples illustrated but also with a mind constantly alert to think out the function and appropriateness of each feature. For the principle of Hellenic construction was that every member should perform a special function. The architect’s logic would not permit him, as we say, to send a boy on a man’s errand or waste a man by employing him at boy’s work, still less to confuse the responsibility for the function between two or more members. Accordingly, the student who is reading intelligently will assure himself at each step as to what particular responsibility was laid upon each member and how appropriately it was fitted to its function.

=Ionic Order.=--From the grandiose simplicity of the Doric order we pass to the slenderer and more graceful and decorated order of the Ionic. It is almost like passing from a masculine to a feminine type: from a reflection of the severe discipline of the old Dorian, as perpetuated by the Spartans, to the more pleasure-loving and elegant life of the wealthy Ionians; from the grave influence of the Olympian Zeus, chief god of the Dorians, to the grace of the youthful Apollo and Artemis, beloved of the Ionians.

For the Ionic order, as the name implies, was developed by the Asiatic Hellenes whose migration from Armenia has been already noted. From them the Greeks of Europe borrowed it. Among the earliest known examples are a =Temple of Apollo= at =Naucratis=, in Egypt, and the archaic =Temple of Artemis=, at =Ephesus=, both belonging to about 560 B.C. The remains of the latter are in the British Museum. They include two capitals, inscribed with the name of Crœsus, who is known to have contributed to the temple.

As in the Doric order, the Ionic temple rested on a _stylobate_ of three steps, but the column is also provided with a base. The latter was usually composed of two _tori_, of semi-circular profile, separated by a concave moulding or _scotia_. Sometimes, as in the =Erechtheion= at Athens, the base stood upon a square, flat base-block, or _plinth_. Frequently the tori were embellished with horizontal flutings or the interlacing wave-lines, called _guilloche_.

The Ionic shaft was proportionately higher than the Doric, being from 8 to 10 diameters in height as compared with the 4⅓ to 7 of the Doric. Consequently, the entasis was less. The intercolumniation was sometimes as much as two diameters. The shaft was incised with twenty-four narrow flutings, separated by flat-edged fillets.

The capital usually commenced with a narrow convex moulding, called the _astragal_, which was often enriched with the alternate bead and spool ornament. Above this was the _echinus_, decorated with the egg-and-dart pattern. But the _echinus_ is only partly visible, since it is encroached upon by the main feature of the capital, a fillet that passes across the face and at the sides winds inward upon itself, forming a _volute_, which projects beyond the _echinus_. Above this was a low _abacus_, enriched with ornament, on which set the _architrave_.

In some instances, as in the =Erechtheion=, the fillet forms a looping curve, the volute is enriched with intermediate fillets and the necking is decorated with the _anthemion_ ornament.

The Ionic capital presented awkward features which the ingenuity of the architects never quite succeeded in disguising. In the first place the abacus projected beyond the face of the architrave which from the side view offered an unsightly appearance. Secondly arose the problem of treating the volutes of the corner columns, so that the effect might be symmetrical on both sides of the building. This was solved by converting the side end of the capital into another face, the adjacent volutes at the corner being brought out at an angle of forty-five degrees. This results in an awkward arrangement at the back where two half-volutes intersect each other at right angles.

The Ionic architrave consists of two or more _fasciæ_, or vertical faces, projecting one over the other. This recalls the original wooden construction and suggests that the Ionians used planks, while the Dorians used a single beam. It was crowned with small mouldings, frequently enriched with ornament.

Above this was the frieze, sometimes left plain, at other times enriched with sculptured reliefs. It was joined by a moulding to the cornice.

The latter, in the simpler form adopted by the Athenians, consisted of a plain corona, a fillet of _bead-and-spool_ ornament, a row of _egg-and-dart_ moulding, and the cymatium or gutter, which was often embellished with lion heads.

In Asiatic-Ionic examples, however, the cornice was more elaborate: a row of narrow blocks or _dentils_, crowned with a carved fillet, being inserted beneath the corona, while, further, the cymatium was embellished with a repeat of the _anthemion_ decoration. This style is distinguished by the term Ornamented Ionic.

The origin of the dentil may probably be traced to the Lycian Tombs, where they are represented by the ends of the beams of the roof or gable. The volute appears as a decorative feature on the façade of the so-called =Tomb of Midas= in =Phrygia=. It also occurs as a decorative feature in Assyrian art and is found in the capitals of the small columns of a pavilion represented in the reliefs at Khorsabad. The motive of the spiral is also found in Mycenæan jewelry. Professor William H. Goodyear in his “Grammar of the Lotus,” suggests that the volute may have originated in successive variations of the Egyptian lotus patterns.

The Doric and Ionic orders were sometimes combined in the same building, as in the =Propylæa=.

=Corinthian Order.=--The Corinthian order represents a still further advance in ornateness, which however by the Hellenic architects was confined to the capital of the column. For the base and shaft of the columns and the entablature followed the Ionic order. The embellishment of the capital may have been derived from the old custom of attaching metal ornaments or actual foliage to altars and pedestals; and it may be possible to trace the growth of the Corinthian style from the Ionic in the repeat of palmettes that occurs below the volutes in the capitals of the east portico of the =Erechtheion=. On the other hand, the general bell-form of the capital may have been derived from Egyptian lotus capitals.

The Corinthian order was used by the Athenians only in their smaller structures[2] and reached its most refined form in the =Choragic Monument= of =Lysicrates= in =Athens=. Here the flutings of the shaft terminate at the top in leaves that curve outward. Above them is a band that may have been covered with a bronze collar, from which spring a row of small lotus leaves. Then come eight beautiful acanthus leaves, between each of which is an eight-petalled rosette, suggesting a lotus-flower. They are surmounted at the corners by stalks of the acanthus, partly sheathed with leaves, that turn over with a spiral and form scrolls to support the abacus. The latter in the Corinthian order has concave sides.

The details vary so much in Hellenic examples of Corinthian capitals that, as we have already noted, the type had not yet been developed into an independent order. Its final development was worked out by the Romans, to whom its magnificence especially appealed.

=Ornament.=--The _acanthus_ plant belongs to Southern Europe and the warmer parts of Asia and Africa. The common species found throughout the Mediterranean, has large, deeply cut, hairy leaves. As a decorative motive the Greeks first reproduced it in metal and then carved it in stone, using it with particularly fine effect on the upright form of tombstone known as _stela_. While they conventionalised the leaves, they preserved the character of vigorous and at the same time graceful growth. They gave a sharpness to the tips of the leaves that distinguishes their use of it from the Roman.

The _anthemion_ ornament is often called the “honeysuckle pattern” from its resemblance to that flower. But it is supposed to be a conventionalisation of the flower of the acanthus, while related as a decorative motive with the forms of the Egyptian lotus and the Persian palmette.

The _egg-and-dart_ border presents a repeat in which the form of an egg, set in a concave oval, alternates with a vertical bar that may or may not terminate below in a more or less pronounced arrow-tip. It permits the most subtle treatment of the planes of the egg, and of the contrast between the smooth surfaces and the sharpness of the other details.

The _bead-and-spool_ repeat explains itself. It shows a variation, according as the conventionalisation was derived from a spool that is wound or that is unwound.

The _heart-leaf_, also sometimes called the _lily-leaf_, is a remarkable instance of the closeness with which the Greek artist studied nature and of the imagination he displayed in simplifying the natural form into a convention, while at the same time preserving the principles of its construction.

=Projections.=--Unlike Egyptian architecture, the Hellenic is distinguished by the number and importance of its projections; which may be compared to the lines, angles, and curves which constitute the features of a human face and give it expression. They are the means by which the architect engraves upon his buildings expressive designs of light and shade. We have already spoken of the projections involved in the column and entablature, but may now specifically enumerate the various types of moulding that these involve; noting at the same time the particular ornament that was employed on each, if it were decorated. For such was the logic and refinement of the Hellenic taste that it adopted motives of ornament that corresponded to the planes of the surfaces of the moulding.

Thus, when the moulding took the form of the _cyma recta_--a curve outward growing into a curve inward--Hogarth’s “line of beauty”--the decorative feature applied to it was the anthemion, whose curves have a corresponding direction. On the other hand, for the reversed form of moulding, known as the _cyma reversa_ where the inward precedes the outward curve, they used the heart-leaf. Again, the moulding known as _ovolo_, in which the contour of an egg is followed, is enriched with the egg-and-dart.

The _fillet_, a small band used to separate the other mouldings, was usually left plain; as also were the simple hollow, called _cavetto_, and the deep hollow which separated the two _tori_ in the base of columns. When the torus was embellished, the motives used on the semicircular surface were the interweave or plait, known as guilloche, or rows of leaves, tied with bands, so that the moulding resembled a wreath. Another small, separating moulding was the _bead_, which in contour approaches a circle, and, when decorated, received the bead-and-spool enrichment.

The distinction of the Hellenic use of all these mouldings and enrichments was the extreme delicacy of the cutting, which the hardness of the marble permitted and the clear sunshine helped to reveal; so that it has been said that “while the Hellenes built like Titans, they finished like jewellers.” But this did not involve a finicking precision, for it was but an instance of the feeling for proportion and choice relation of parts to one another that embraced the whole building.

=Organic Relations.=--The height of the building was thoughtfully proportioned to the length and width; the height of the shaft of the column was considered in relation to the diameter. Similar care was expended on the proportions of the several members of the capitals and entablature, and the intercolumniation bore relation to the lower diameter of the shafts. In every particular, great or little, the effort was to create a unified impression of organic harmony and rhythmical relations.

Now the term organic is primarily used of the living bodies of animals and plants, the parts of which are not only connected but perform certain functions in relation to the well-being of the whole. And it is an extension of this idea that the Hellenes applied to the geometrical harmony on which their architecture was based. They considered the functions of each part--the amount of support it gave or strain it had to sustain and so forth; and having made provision for this as constructors, they were consistent to the principle also in their æsthetic consideration as artists. They modified the sculptural decoration according to the function of the parts; giving least to those whose function of support was most important and increasing the quantity and the boldness of the curving as the structural strain diminished.

Thus the shaft of the column was free of any carving except the fluting, which, however, served the purpose of channels to carry the rain water and helped to preserve the mass from decay. The capital in the Doric style was not enriched with ornament, and similarly plain, with very few exceptions, was the architrave. Meanwhile, sculptured figures in high relief were introduced into the metopes which originally had been openings, while the _tympanum_ or flat surface of the pediment received groups of figures in the round. This increased boldness of relief, accompanied by foreshortening of the figures, was adopted to offset the diminishing effect that their greater distance from the spectator’s eye would otherwise have suggested. Moreover, in the sculptures, as in the carving of the mouldings, the varying quantities of light were considered. The mouldings on the outside of a temple in full sunlight were differently planned from those in the interior; and the shadow cast by the cornices was taken into account in graduating the relief of the sculptures in the metopes and pediments.

Nor was the actual work done by artists, but under their supervision by pupils and masons. From the records of payments made to the sculptors who worked on the Erechtheion it appears that they were ordinary masons, some of them not even citizens, who were paid for each figure the sum of 60 drachms, or 12 dollars!

Finally, the decoration of a Greek Temple comprised not only sculpture, but also painting. A large part of every Doric temple was covered with strong, bright colours, while certain prominent details were treated with elaborate patterns. The figures of the sculpture also were painted and relieved against a background of contrasted colour.

It has been discovered that the triglyphs were painted blue and the metopes red and that the mouldings were decorated with ornament in red, blue, green, and gold. The walls and the columns were probably stained yellow or buff, perhaps by the use of wax melted on the surface (_encaustic_).

=Asymmetries or Refinements.=--It might seem that, in the various particulars we have noted, Hellenic intellect and feeling had exhausted the possibilities of refinement. But there is yet another instance, which was first revealed by the detailed measurements of Hellenic temples made independently by two Englishmen, Francis Cranmer Penrose and John Pennethorne, and by a German architect, Joseph Hoffer. The results were published in 1838 and in 1851, and have been corroborated by other students. They are known as architectural “refinements” or “asymmetries.”

It had been assumed that, since the form of the temple type was apparently symmetrical, it also involved absolute symmetry of details; that geometrical regularity and mathematical accuracy were the necessary and natural conditions of the architectural design. By those investigators, however, it was discovered that though the principles of geometry and mathematics were the foundation of the planning and designing, regularity and accuracy were purposely avoided; and that so far from the details being symmetrical they exhibit intentional asymmetries.

One of these irregularities is the substitution of curved for straight lines. We have already mentioned the entasis or swell in the vertical contour of the column--a fact not observed by modern architects until 1810; but curvature is also found in the horizontal lines of the stylobate and the architrave, frieze, and cornice, and in the gable lines of the pediments. And since these were discovered other variations of equal importance and significance have been found.

“In the =Parthenon=, for instance,” (the quotation is from the writings of Professor William H. Goodyear) “surfaces or members which are set true to perpendicular are most exceptional. Perhaps the end walls are the only exception. All the columns lean inward about three inches in thirty feet toward the centre of the building. The side walls lean inward. The antæ, or flat pilasters at the angles of the ends of the walls, lean forward one unit in eighty-two units. The faces of the architrave and frieze lean backward, whereas the acroteria, the face of the cornice and the face of the fillet between architrave and frieze lean forward. Furthermore, the columns and capitals of the Parthenon are of unequal size, and the widths of the metopes and the intercolumnar spacings are also unequal.”

The discovery of these variations was pooh-poohed by architects who had been trained to believe that “correct” architecture depended upon geometrical regularity and mathematical accuracy. They dismissed them lightly as “mason’s errors.” But this will not hold for three reasons. Firstly, these asymmetries only occur in the finest examples, where the design and the details are of superior refinement and the skill of the masons most unmistakable. Secondly, the number of variations increases _pro rata_ with the superiority of the design, reaching their maximum in the =Parthenon=. And, thirdly, in cases which are unquestionably due to mason’s errors the amount of the variation is practically negligible. Is it likely, for example, that the masons who brought the two ends of the Parthenon within one quarter of an inch of being exactly equal in width, would have been so careless as to let the presumably horizontal lines curve up four inches on the sides of the buildings and two inches at its ends? Or, again, would they have committed so flagrant an error as giving the stylobate a convex curve upward, since it necessitated a corresponding curve to the base of each column, a most difficult and delicate operation of cutting? The perfect adjustment of these two curves, by the way, is one of many arguments against the theory that these variations were caused by settlements in the foundations or, in the case of the Parthenon, by the explosion which wrecked it in 1687, when it was being used by the Turks as a powder magazine.

The fact having been established that these variations were intentional, how are they to be explained? A generally accepted explanation of the curvatures in place of straight lines has been that they were intended to correct an optical effect of curvature in the opposite direction. Thus, if the contour of a column shaft were a straight line, it would appear to the eye to curve inward; similarly, the horizontal lines of the stylobate and entablature would appear to sag downward. Accordingly, the “refinements” were designed as optical corrections of optical effects of irregularity; in other words, geometrical effect is supposed to have been sought by departures from geometric fact.

This, however, would not explain the other variations that have been noted. Moreover, it is contradicted even in the case of curvatures by a discovery of Professor Giovannoni of Rome, that the façade of the =Temple= at =Uri= has a curvature in _plan_.[3] The columns, that is to say, are not set to a straight line but to a curve which is concave to the exterior; consequently the entablature is correspondingly curved, the effect of which to the eye as it looks up is the very one that it was explained the architects strove to avoid--a sag downward from the ends. In this case they deliberately designed the façade to produce the effect.

This explanation of optical corrections, then, as well as others, have been proved erroneous by Professor William H. Goodyear, who has made a life-long study of the subject and carried his investigations also into Gothic architecture, in which, as we shall see, he has discovered numerous instances of refinements and asymmetries. His explanation, supported by a wealth of conclusive evidence which is set forth in his “Greek Refinements,” is that the motive was æsthetic. The refinements were modulations designed to please the eye by avoiding the inartistic effects produced by formal monotony. They were planned to do away with the monotony and rigidity that result from geometrical regularity and mathematical accuracy and to introduce a suggestion of elasticity. They imparted to the structure something of the irregularity that characterises organic growth. It is because, with rare exceptions, they are not found in modern classical buildings, that the latter appear by comparison so stiff and formal.

These asymmetries, in fact, were intended to offset the liability of the beauty’s becoming “faultily faultless, icily regular, splendidly null, dead perfection, no more.”

With few exceptions the Hellenic temple was oriented; its four sides facing exactly the four points of the compass, the principal entrance being on the east. It opened into the cella which was usually divided into what may be called a nave and side aisles by two rows of columns which carried smaller columns that supported the pitch of the roof. Where the cella was narrow, as in the =Temple of Apollo Epicurios= (“The Helper”) at =Bassæ=, near Phigaleia, the rows of columns were replaced by half-columns, attached to projections from side walls. The cella was occupied by the statue of the deity, which in the case of the =Parthenon= was the Athene Parthenos, the Maiden Athene, one of the most renowned works of Phidias. The draped figure of the goddess was represented standing, armed with helmet, spear and shield, supporting in one hand a Wingèd Victory. The statue was about forty feet high and of the kind known as “chryselephantine,” the draperies and accessories being of gold plates, the flesh parts ivory, with precious stones inserted in the eyes.

Behind this statue was the entrance to a small room, situated between the cella and the opisthodomos, an exceptional feature from which the name of the temple was derived. It was the Parthenon proper, or Virgin’s Chamber, which seems to have been used as a treasury. Its ceiling was supported by four Ionic columns.

The Ionic order in conjunction with the Doric was also employed in the =Propylæa= or monumental gateway of the =Acropolis=. This masterpiece of Mnesicles presents an irregularity of plan, exhibiting the Hellenic architect’s readiness to adapt his design to the peculiarities of the site. While Doric columns mark the exterior, Ionic were used in the interior to dignify the central passageway. A similar use of this order for interior embellishment was adopted by Ictinus, the chief architect of the Parthenon, in his otherwise Doric design of the =Temple= of =Apollo Epicurios=.

On the other hand, the Ionic order was employed on the exterior of the =Erechtheion=, another work of Mnesicles also irregular in plan. It occupies a sloping site on the Acropolis, where an older temple, burnt by the Persians, had stood. Spoils of the Persian conquest were preserved in it with other relics, held in special veneration. The nucleus of the design is a cella without colonnades (apteral), the sanctuary of Athena Polias (the City’s Guardian) and of Erechtheus (a mythic hero of the Athenians) and the Ocean-god, Poseidon. The exterior is distinguished by two Ionic porticoes, and by a third, a smaller one, in which the columns are replaced by caryatides, six draped female figures whose heads support the architrave. All these figures face south, the three to the west resting their weight on the right legs; the three eastern on the left--in each case the outer legs--thus giving to the outer contour of their bodies the effect of entasis.

Another Ionic example on the Acropolis is the =Temple of Athene Nike= (Victory), known as the Temple of =Nike= =Apteros=; the term “Wingless,” however, not describing the statue of the goddess but, as used above, the style of the design--without colonnades.

=Theatres.=--Only second in importance to the Hellenic temples were the theatres. Both served as memorials of the ancient traditions of the race and as an incentive to higher citizenship. For the drama, which had its origin in religious observances, was a civic institution, maintained by the state and free to all citizens.

The origin of the Greek drama is to be found in the primitive worship of Dionysos, the god of productiveness, and to the last the Greek stage and auditorium perpetuated in their form some trace of their religious origin. The nucleus was an altar consecrated to Dionysos. In earliest times each family may have erected its own altar, presided over by the father of the family as priest. Later each community would have its official priest, and on the god’s feast-day all the villagers would move in procession to the common altar, headed by the priest and a choir of singers, trained by him. The altar reached, the priest would mount the pedestal, surrounded by the choir, while the body of worshippers disposed themselves around the spot. The priest would recite the greatness of the god and at intervals the choir of voices would chant the dithyrambic song, moving around the altar and accompanying the song with rhythmic movement of body and limbs.

From this root of a religious drama in time grew successive stems. The prowess of some hero would be adopted as a theme. At first the priest, or it may be some wandering poet, would narrate the story; later he would treat it in the first person, impersonating the hero, sometimes engaging in dialogue with the chorus. Still later, other personages in the story would be separately impersonated, and so the scope of the dramatic representation developed.

Meanwhile the affair still maintained a semi-religious character; the place of presentation was still around the altar of Dionysos and the chorus was retained, taking its part in the action with explanation and comment, still delivered, however, in dithyrambic measure and with accompaniments of rhythmic gesture. The platform of the altar being limited in space, the dialogue was usually confined to two actors at a time, though a third was sometimes allowed. If there were other characters involved, these actors would often “double” the parts; disguising themselves by change of costume, especially by the use of masks. This demanded some kind of a screen behind which the actors could change their costumes and also wait until their presence was required. Skins hung upon poles would at first serve the purpose, or a _skene_ or tent, from which we derive our word scene, might be used. Whichever it were, it would interfere with the view of the action from the back and so draw the audience to the “front.”

The most important remains of Hellenic theatres are the =Theatre of Dionysos=,[4] cut out of the side of the Acropolis, and the theatre at =Epidauros=, in Argolis, Greece. The plan of the theatre of Dionysos is that of a semi-circle, the ends of which are prolonged for a short distance in a direction at right angles to the front of the skene. Within the horseshoe was the circular orchestra, still whole at =Epidauros=, in which the main action was carried on by actors and chorus. A different plan is given by the Roman architect, Vitruvius. It is to be noted, however, that Vitruvius lived in the reign of Augustus, by which time what was pure Hellenic had become modified by foreign influences into Hellenistic. He relates, for example, that in his time the height of the _logeion_ or speaking platform--the stage of to-day--was from 10 to 12 feet. In earlier times, including probably the period of the Classic drama, the logeion was the platform around the altar, supplemented possibly by a platform two or three feet high extending across the front of the _skene_, from which, at certain points in the play, some, at least, of the actors spoke. This platform, being in front of the scene and enclosed at the sides by projections of the latter, was called the _proskenion_, from which is derived our word proscenium with its different meaning.

By the time that the Hellenic theatre had evolved into a permanent structure, the _skene_, originally a temporary screen, took the form of an architectural background, some ten feet high, with a central door for the entrances of the actors. But the idea of the original screen was perhaps retained in the row of columns which stood a little in front of the _skene_, and could be used, if needed, for the hanging of curtains or even of painted cloths. Meanwhile, the roof of the portico, which extended from the columns to the _skene_, could be utilised by the actors at certain stages of the drama.[5]

The interest of the discussion raised by Vitruvius’ description consists in the question how far the actors mingled with or were separated from the chorus, which continued to occupy the _orchestra_ or circle on the floor of the auditorium, corresponding to the place of the orchestra stalls in a modern theatre. The orchestra of a Greek theatre was originally the sole “stage,” but gradually, as the dramas involved more complexity of scenes, the actors would vary their position between the orchestra and the proscenium; and later, in Hellenistic times, as the religious origin of the drama was forgotten and the use of a chorus began to fall into abeyance, the use of the proscenium would increase.

Finally, when the Romans began to imitate the Greek drama, they dropped the chorus; the acting was confined to the proscenium, and the orchestra no longer needed for the play, became a part of the auditorium, reserved for distinguished spectators. The Roman theatre, in fact, like our own, represented the complete separation of the audience and the stage.

=Odeion.=--Supplementing the theatre was the Odeion or concert hall, which was constructed on the same general lines but distinguished by the addition of a roof for acoustic purposes. The oldest known is the =Skias= at Sparta, so called from its roof resembling the top of a parasol. The =Odeion of Pericles=, which served as a model for subsequent halls, was built on the southeastern slope of the Acropolis, its roof being made in imitation of the tent of Xerxes and constructed of the masts of Persian vessels, captured at the battle of Salamis. The most magnificent example, however, was erected A.D. 162 on the southwest slope, by a wealthy citizen, =Herodes Atticus=, in memory of his wife. Its ceiling is said to have been composed of beams of cedar, carved with ornament, while decorations in the form of paintings and other works of art embellished the interior, which had accommodation for eight thousand persons.
