THE FINE ARTS.

ARCHITECTURE, SCULPTURE, PAINTING.

500-430 B.C.

My object in the present lecture is not a criticism of the principles of art so much as an enumeration of its various forms among the ancients, to show that in this department of civilization they reached remarkable perfection, and were not inferior to modern Christian nations.

The first development of art among all the nations of antiquity was in architecture. The earliest buildings erected were houses to protect people from heat, cold, and the fury of the elements of Nature. At that remote period much more attention was given to convenience and practical utility than to beauty or architectural effect. The earliest houses were built of wood, and stone was not employed until temples and palaces arose. Ordinary houses were probably not much better than log-huts and hovels, until wealth was acc.u.mulated by private persons.

The earliest monuments of enduring magnificence were the temples of powerful priests and the palaces of kings; and in Egypt and a.s.syria these appear earliest, as well as most other works showing civilization.

Perhaps the first great monument which arose after the deluge of Noah was the Tower of Babel, built probably of brick. It was intended to be very lofty, but of its actual height we know nothing, nor of its style of architecture. Indeed, we do not know that it was ever advanced beyond its foundations; yet there are some grounds for supposing that it was ultimately finished, and became the princ.i.p.al temple of the Chaldaean metropolis.

From the ruins of ancient monuments we conclude that architecture received its earliest development in Egypt, and that its effects were imposing, ma.s.sive, and grand. It was chiefly directed to the erection of palaces and temples, the ruins of which attest grandeur and vastness.

They were built of stone, in blocks so huge and heavy that even modern engineers are at loss to comprehend how they could have been transported and erected. All the monuments of the Pharaohs are wonders, especially such as appear in the ruins of Karnak,--a temple formerly designated as that of Jupiter Ammon. It was in the time of Sesostris, or Rameses the Great, the first of the Pharaohs of the nineteenth dynasty, that architecture in Egypt reached its greatest development. Then we find the rectangular-cut blocks of stone in parallel courses, the heavy pier, the cylindrical column with its bell-shaped capital, and the bold and ma.s.sive rectangular architraves extending from pier to pier and column to column, surmounted by a deep covered coping or cornice.

The imposing architecture of Egypt was chiefly owing to the impressive vastness of the public buildings. It was not produced by beauty of proportion or graceful embellishments; it was designed to awe the people, and kindle sentiments of wonder and astonishment. So far as this end was contemplated it was n.o.bly reached; even to this day the traveller stands in admiring amazement before those monuments that were old three thousand years ago. No structures have been so enduring as the Pyramids; no ruins are more extensive and majestic than those of Thebes.

The temple of Karnak and the palace of Rameses the Great were probably the most imposing ever built by man. This temple was built of blocks of stone seventy feet in length, on a platform one thousand feet long and three hundred wide, with pillars sixty feet in height. But this and other structures did not possess that unity of design which marked the Grecian temples. Alleys of colossal sphinxes formed the approach. At Karnak the alley was six thousand feet long, and before the main body of the edifice stood two obelisks commemorative of the dedication. The princ.i.p.al structures of Egyptian temples do not follow the straight line, but begin with pyramidal towers which flank the gateways; then follow, usually, a court surrounded with colonnades, subordinate temples, and houses for the priests. A second pylon, or pyramidal tower, leads to the interior and most considerable part of the temple,--a portico inclosed with walls, which receives light only through the entablature or openings in the roof. Adjoining this is the cella of the temple, without columns, enclosed by several walls, often divided into various small chambers with monolithic receptacles for idols or mummies or animals. The columns stand within the walls. The colonnade is not, as among the Greeks, an expansion of the temple; it is merely the wall with apertures. The walls, composed of square blocks, are perpendicular only on the inside, and bevelled externally, so that the thickness at the bottom sometimes amounts to twenty-four feet; thus the whole building a.s.sumes a pyramidal form, the fundamental principle of Egyptian architecture. The columns are more slender than the early Doric, are placed close together, and have bases of circular plinths; the shaft diminishes upward, and is ornamented with perpendicular or oblique furrows, but not fluted like Grecian columns. The capitals are of the bell form, ornamented with all kinds of foliage, and have a narrow but high abacus. They abound with sculptured decorations, the designs of which were borrowed from the vegetation of the country. The highest of the columns of the temple of Luxor is five and a quarter times the greatest diameter.

But no monuments have ever excited so much curiosity and wonder as the Pyramids, not in consequence of any particular beauty or ingenuity in their construction, but because of their immense size and unknown age.

None but sacerdotal monarchs would ever have erected them; none but a fanatical people would ever have toiled upon them. We do not know for what purpose they were raised, unless as sepulchres for kings. They are supposed to have been built at a remote antiquity, between two thousand and three thousand years before Christ. Lepsius thought that the oldest of these Pyramids were built more than three thousand years before Christ. The Pyramid of Cheops, at Memphis, covers a square whose side is seven hundred and sixty-eight feet, and rises into the air nearly five hundred feet. It is a solid ma.s.s of stone, which has suffered less from time than the mountains near it. Possibly it stands over an immense substructure, in which may yet be found the lore of ancient Egypt; it may even prove to be the famous labyrinth of which Herodotus speaks, built by the twelve kings of Egypt. According to this author, one hundred thousand men worked on this monument for forty years.

The palaces of the kings are mere imitations of the temples, their only difference of architecture being that their rooms are larger and in greater numbers. Some think that the famous labyrinth was a collective palace of many rulers.

Of Babylonian architecture we know little beyond what the Hebrew Scriptures and ancient authors tell us. But though nothing survives of ancient magnificence, we know that a city whose walls, according to Herodotus, were eighty-seven feet in thickness, three hundred and thirty-seven in height, and sixty miles in circ.u.mference, and in which were one hundred gates of bra.s.s, must have had considerable architectural splendor. This account of Babylon, however, is probably exaggerated, especially as to the height of the walls. The tower of Belus, the Palace of Nebuchadnezzar, and the Obelisk of Semiramis were probably wonderful structures, certainly in size, which is one of the conditions of architectural effect.

The Tyrians must have carried architecture to considerable perfection, since the Temple of Solomon, one of the most magnificent in the ancient world, was probably built by artists from Tyre. It was not remarkable for size,--it was, indeed, very small,--but it had great splendor of decoration. It was of quadrangular outline, erected upon a solid platform of stone, and bearing a striking resemblance to the oldest Greek temples, like those of Aegina and Paestum. The portico of the Temple as rebuilt by Herod was one hundred and eighty feet high, and the Temple itself was entered by nine gates, thickly coated with silver and gold. The inner sanctuary was covered on all sides with plates of gold, and was dazzling to the eye. The various courts and porticos and palaces with which it was surrounded gave to it a very imposing effect.

Architectural art in India was not so impressive and grand as in Egypt, and was directed chiefly to the erection of temples. Nor is it of very ancient date. There is no stone architecture now remaining in India, according to Sir James Fergusson, older than two and a half centuries before Christ; and this is in the form of Buddhist temples, generally traced to the great Asoka, who reigned from 272 B.C. to 236 B.C., and who established Buddhism as a state religion. There were doubtless magnificent buildings before his time, but they were of wood, and have all perished. We know, however, nothing about them.

The Buddhist temples were generally excavated out of the solid rock, and only the facades were ornamented. These were not larger than ordinary modern parochial churches, and do not give the impression of extraordinary magnificence. Besides these rock-hewn temples in India there remain many examples of a kind of memorial monument called _stupas_, or _topes_. The earliest of these are single columns; but the later and more numerous are in the shape of cones or circular mounds, resembling domes, rarely exceeding one hundred feet in diameter. Around the apex of each was a bal.u.s.trade, or some ornamental work, about six feet in diameter. These topes remind one of the Pantheon at Rome in general form, but were of much smaller size. They were built on a stone bas.e.m.e.nt less than fifty feet in height, above which was the brickwork.

In process of time they came to resemble pyramidal towers rather than rounded domes, and were profusely ornamented with carvings. The great peculiarity of all Indian architectural monuments is excessive ornamentation rather than beauty of proportion or grand effect.

In course of time, however, Indian temples became more and more magnificent; and a Chinese traveller in the year 400 A.D. describes one in Gaudhava as four hundred and seventy feet high, decorated with every sort of precious substance. Its dome, as it appears in a bas-relief, must have rivalled that of St. Peter's at Rome; but no trace of it now remains. The topes of India, which were numerous, indicate that the Hindus were acquainted with the arch, both pointed and circular, which was not known to the Egyptians or the Greeks. The most important of these buildings, in which are preserved valuable relics, are found in the Punjab. They were erected about twenty years before Christ. In size, they are about one hundred and twenty-seven feet in diameter. Connected with the circular topes are found what are called _rails_, surrounding the topes, built in the form of rectangles, with heavy pillars. One of the most interesting of these was found to be two hundred and seventy-five feet long, having square pillars twenty-two feet in height, profusely carved with scenes from the life of Buddha, topped by capitals in the shape of elephants supporting a succession of horizontal stone beams, all decorated with a richness of carving unknown in any other country. The Amravati rail, one of the finest of the ancient monuments of India, is found to be one hundred and ninety-five by one hundred and sixty-five feet, having octagonal pillars ornamented with the most elaborate carvings.

From an architectural point of view, the rails were surpa.s.sed by the _chaityas_, or temple-caves, in western India. These were cut in the solid rock. Some one thousand different specimens are to be found. The facades of these caves are perfect, generally in the form of an arch, executed in the rock with every variety of detail, and therefore imperishable without violence. The process of excavation extended through ten centuries from the time of Asoka; and the interiors as well as the facades were highly ornamented with sculptures. The temple-caves are seldom more than one hundred and fifty feet deep and fifty feet in width, and the roofs are supported by pillars like the interior of Gothic cathedrals, some of which are of beautiful proportions with elaborated capitals. Though these rock-hewn temples are no larger than ordinary Christian churches, they are very impressive from the richly decorated carvings; they were lighted from a single opening in the facade, sometimes in the shape of a horseshoe.

Besides these chaityas, or temples, there are still more numerous _viharas_, or monasteries, found in India, of different dates, but none older than the third century before Christ. They show a central hall, surrounded on three sides by cells for the monks. On the fourth side is an open verandah; facing this is generally a shrine with an image of Buddha. These edifices are not imposing unless surrounded by galleries, as some were, supported by highly decorated pillars. The halls are constructed in several stories with heavy masonry, in the shape of pyramids adorned with the figures of men and animals. One of these halls in southern India had fifteen hundred cells. The most celebrated was the Nalanda monastery, founded in the first century by Nagarjuna, which accommodated ten thousand priests, and was enclosed by a wall measuring sixteen hundred feet by four hundred. It was to Central India what Mount Casino was to Italy, and Cluny was to France, in the Middle Ages,--the seat of learning and art.

It was not until the Mohammedan conquest in India that architecture received a new impulse from the Saracenic influence. Then arose the mosques, minarets, and palaces which are a wonder for their magnificence, and in which are seen the influence of Greek art as well as that of India. There is an Oriental splendor in these palaces and mosques which has called out the admiration of critics, although it is different from those types of beauty which we are accustomed to praise.

But these later edifices were erected in the Middle Ages, coeval with the cathedrals of Europe, and therefore do not properly come under the head of ancient art, in which the ancient Hindus, whether of Aryan or Turanian descent, did not particularly excel. It was in matters of religion and philosophy that the Hindus felt most interest, even as the ancient Jews thought more of theology than of art and science.

Architecture, however, as the expression of genius and high civilization, was carried to perfection only by the Greeks, who excelled in so many things. It was among the ancient Dorians, who descended from the mountains of northern Greece eighty years after the fall of Troy, that architectural art worthy of the name first appeared. The Pelasgi erected Cyclopean structures fifteen hundred years before Christ, as seen in the ma.s.sive walls of the Acropolis at Athens, constructed of huge blocks of hewn stone, and in the palaces of the princes of the heroic times. The lintel of the doorway of the Mycenaean treasury is composed of a single stone twenty-seven feet long and sixteen broad. But these edifices, which aimed at splendor and richness merely, were deficient in that simplicity and harmony which have given immortality to the temples of the Dorians. In this style of architecture everything was suitable to its object, and was grand and n.o.ble. The great thickness of the columns, the beautiful entablature, the ample proportion of the capital, the great horizontal lines of the architrave and cornice predominating over the vertical lines of the columns, the severity of geometrical forms produced for the most part by straight lines, gave an imposing simplicity to the Doric temple.

How far the Greek architects were indebted to the Egyptian we cannot tell, for though columns are found amid the ruins of the Egyptian temples, they are of different shape from any made by the Greeks. In the structures of Thebes we find both the tumescent and the cylindrical columns, from which amalgamation might have been produced the Doric column. The Greeks seized on beauty wherever they found it, and improved upon it. The Doric column was not probably an entirely new creation, but shaped after models furnished by the most original of all the ancient nations, even the Egyptians. The Doric temples were uniform in plan. The columns were fluted, and were generally about six diameters in height; they diminished gradually upward from the base, with a slightly con vexed swelling; they were surmounted by capitals regularly proportioned according to their height. The entablature which the column supported was also of a certain number of diameters in height. So regular and perfect was the plan of the temple, that "if the dimensions of a single column and the proportion the entablature should bear to it were given to two individuals acquainted with the style, with directions to compose a temple, they would produce designs exactly similar in size, arrangement, and general proportions." The Doric order possessed a peculiar harmony, but taste and skill were nevertheless necessary in order to determine the number of diameters a column should have, and also the height of the entablature.

The Doric was the favorite order of European Greece for one thousand years, and also of her colonies in Sicily and Magna Graecia. It was used exclusively until after the Macedonian conquest, and was chiefly applied to temples. The ma.s.sive temples of Paestum, the colossal magnificence of the Sicilian ruins, and the more elegant proportions of the Athenian structures, like the Parthenon and Temple of Theseus, show the perfection of the Doric architecture. Although the general style of all the Doric temples is so uniform, hardly two temples were alike. The earlier Doric was more ma.s.sive; the later was more elegant, and its edifices were rich in sculptured decorations. Nothing could surpa.s.s the beauty of a Doric temple in the time of Pericles. The stylobate, or general base upon which the columnar story stood, from two thirds to a whole diameter of a column in height, was built in three equal courses, which gradually receded upward and formed steps, as it were, of a grand platform. The column, simply set upon the stylobate, without base or pedestal, was from four to six diameters in height, with twenty flutes, having a capital of half a diameter. On this rested the entablature, two column-diameters in height, which was divided into architrave (lower mouldings), frieze (broad middle s.p.a.ce), and cornice (upper mouldings).

The great beauty of the temple was the portico in front,--a forest of columns supporting the triangular pediment, about a diameter and a half to the apex, making an angle at the base of about fourteen degrees.

From the pediment projects the cornice, while in the apex and at the base of the flat three-cornered gable are sculptured ornaments, generally the figures of men or animals. The whole outline of columns supporting the entablature is graceful, while the variety of light and shade arising from the arrangement of mouldings and capitals produces a grand effect.

The Parthenon, the most beautiful specimen of the Doric, has never been equalled, and it still stands august in its ruins, the glory of the old Acropolis and the pride of Athens. It was built of white Pentelic marble, and rested on a bas.e.m.e.nt of limestone. It was two hundred and twenty-seven feet in length, one hundred and one in breadth, and sixty-five in height, surrounded with forty-eight fluted columns, six feet and two inches at the base and thirty-four feet in height, while within the peristyle, at either end, was an interior range of columns standing before the end of the cella. The frieze and the pediment were elaborately ornamented with reliefs and statues, and the cella, within and without, was adorned with the choicest sculptures of Phidias, The remains of the exquisite sculptures of the pediment and the frieze were in the early part of this century brought from Greece by Lord Elgin, purchased by the English government, and placed in the British Museum, where, preserved from further dilapidation, they stand as indisputable evidence of the perfection of Greek art. The grandest adornment of the temple was the colossal statue of Minerva in the eastern apartment of the cella, forty feet in height, composed of gold and ivory; the inner walls of the chamber were decorated with paintings, and the whole temple was a repository of countless treasure. But the Parthenon, so regular to the eye with its vertical, oblique, and horizontal lines, was curved in every line, with the exception of the gable,--with its entablature, architrave, frieze, and cornice, together with the bas.e.m.e.nt, all arched upwards; and even the columns had a slight convexity of vertical line, amounting to 1/550 of the entire height of shaft, though so slightly as not to be perceptible. These curved lines gave to the structure a peculiar grace which cannot be imitated, as well as an effect of solidity.

Nearly coeval with the Doric was the Ionic order, invented by the Asiatic Greeks, still more graceful, though not so imposing. The Acropolis is a perfect example of this order. The column is nine diameters in height, with a base, while the capital is more ornamented than the Doric. The shaft is fluted with twenty-four flutes and alternate fillets (flat longitudinal ridges), and the fillet is about a quarter the width of the flute. The pediment is flatter than that of the Doric order, and more elaborate. The great distinction of the Ionic column is a base, and a capital formed with volutes (spiral scrolls), the shaft also being more slender. Vitruvius, the greatest authority among the ancients in architecture, says that "the Greeks, in inventing these two kinds of columns, imitated in the one the naked simplicity and dignity of man, and in the other the delicacy and ornaments of woman; the base of the Ionic was the imitation of sandals, and the volutes of ringlets." The discoveries of many of the Ionic ornamentations among the remains of a.s.syrian architecture indicate the Oriental source of the Ionic ideas, just as the Doric style seems to have originated in Egypt.

The artistic Greeks, however, always simplified and refined upon their masters.

The Corinthian order exhibits a still greater refinement and elegance than the other two, and was introduced toward the end of the Peloponnesian War. Its peculiarity consists in columns with foliated capitals modelled after the acanthus leaf, and still greater height, about ten diameters, surmounted with a more ornamented entablature. Of this order the most famous temple in Greece was that of Minerva at Tegea, built by Scopas of Paros, but destroyed by fire four hundred years before Christ.

Nothing more distinguished Greek architecture than the variety, the grace, and the beauty of the mouldings, generally in eccentric curves.

The general outline of the moulding is a gracefully flowing cyma, or wave, concave at one end and convex at the other, like an Italic _f_, the concavity and convexity being exactly in the same curve, according to the line of beauty which Hogarth describes.

The most beautiful application of Greek architecture was in the temples, which were very numerous and of extraordinary grandeur, long before the Persian War. Their entrance was always from the west or the east. They were built either in an oblong or round form, and were mostly adorned with columns. Those of an oblong form had columns either in the front alone, or in the eastern and western fronts, or on all the four sides.

They generally had porticos attached to them, and were without windows, receiving their light from the door or from above. The friezes were adorned with various sculptures, as were sometimes the pediments, and no expense was spared upon them. The most important part of the temple was the cell (_cella,_ or temple proper, a square chamber), in which the statue of the deity was kept, generally surrounded with a bal.u.s.trade. In front of the cella was the vestibule, and in the rear or back a chamber in which the treasures of the temple were kept. Names were applied to the temples as well as to the porticos, according to the number of columns in the portico at either end of the temple,--such as the tetrastyle (four columns in front), or hexastyle (when there were six).

There were never more than ten columns across the front. The Parthenon had eight, but six was the usual number. It was the rule to have twice as many columns along the sides as in front. Some of the temples had double rows of columns on all sides, like that of Diana at Ephesus and of Quirinus at Rome. The distance between the columns varied from one diameter and a half to four diameters. About five eighths of a Doric temple were occupied by the cella, and three eighths by the portico.

That which gives to the Greek temples so much simplicity and harmony,--the great elements of beauty in architecture,--is the simple outline in parallelogrammic and pyramidal forms, in which the lines are uninterrupted through their entire length. This simplicity and harmony are more apparent in the Doric than in any of the other orders, but pertain to all the Grecian temples of which we have knowledge. The Ionic and Corinthian, or the voluted and foliated orders, do not possess that severe harmony which pervades the Doric; but the more beautiful compositions are so consummate that they will ever be taken as models of study.

There is now no doubt that the exteriors of the Grecian temples were ornamented in color,--perhaps with historical pictures, etc.,--although as the traces have mostly disappeared it is impossible to know the extent or mode of decoration. It has been thought that the mouldings also may have been gilded or colored, and that the background of the sculptures had some flat color laid on as a relief to the raised figures. We may be sure, however it was done, that the effect was not gaudy or crude, but restrained within the limits of refinement and good taste by the infallible artistic instinct of those masters of the beautiful.

It is not the magnitude of the Greek temples and other works of art which most impresses us. It is not for this that they are important models; it is not for this that they are copied and reproduced in all the modern nations of Europe. They were generally small compared with the temples of Egypt, and with the vast dimensions of Roman amphitheatres; only three or four would compare in size with a Gothic cathedral,--the Parthenon, the Temple of Olympian Zeus at Athens, and the Temple of Diana at Ephesus; even the Pantheon at Rome is small, compared with the later monuments of the Caesars. The traveller is always disappointed in contemplating the ruins of Greek buildings so far as size is concerned. But it is their matchless proportions, their severe symmetry, the grandeur of effect, the undying beauty, the graceful form which impress us, and make us feel that they are perfect.

By the side of the Colosseum they are insignificant in magnitude; they do not cover acres, like the baths of Caracalla. Yet who has copied the Flavian amphitheatre; who erects an edifice after the style of the Thermae? All artists, however, copy the Parthenon. That, and not the colossal monuments of the Caesars, reappears in the capitals of Europe, and stimulates the genius of a Michael Angelo or a Christopher Wren.

The flourishing period of Greek architecture was during the period from Pericles to Alexander,--one hundred and thirteen years. The Macedonian conquest introduced more magnificence and less simplicity. The Roman conquest accelerated the decline in severe taste, when different orders began to be used indiscriminately.

In this state the art pa.s.sed into the hands of the masters of the world, and they inaugurated a new era in architecture. The art was still essentially Greek, although the Romans derived their first knowledge from the Etruscans. The Cloaca Maxima, or Great Sewer, was built during the reign of the second Tarquin,--the grandest monument of the reign of the kings. It is not probable that temples and other public buildings in Rome were either beautiful or magnificent until the conquest of Greece, after which Grecian architects were employed. The Romans adopted the Corinthian style, which they made even more ornamental; and by the successful combination of the Etruscan arch with the Grecian column they laid the foundation of a new and original style, susceptible of great variety and magnificence. They entered into architecture with the enthusiasm of their teachers, but in their pa.s.sion for novelty lost sight of the simplicity which is the great fascination of a Doric temple. Says Memes:--

"They [the Romans] deemed that lightness and grace were to be attained not so much by proportion between the vertical and the horizontal as by the comparative slenderness of the former. Hence we see a poverty in Roman architecture in the midst of profuse ornament. The great error was a constant aim to lessen the diameter while they increased the elevation of the columns. Hence the ma.s.sive simplicity and severe grandeur of the ancient Doric disappear in the Roman, the characteristics of the order being frittered down into a multiplicity of minute details."

When the Romans used the Doric at all, they used a base for the column, which was never done at Athens. They also altered the Doric capital, which cannot be improved. Again, most of the Grecian Doric temples were peripteral,--surrounded with pillars on all the sides. But the Romans built with porticos on one front only, which had a greater projection than the Grecian. They generally were projected three columns, while the Greek portico had usually but a single row. Many of the Roman temples are circular, like the Pantheon, which has a portico of eight columns projected to the depth of three. Nor did the Romans construct hypaethral or uncovered temples with internal columns, like the Greeks. The Pantheon is an exception, since the dome has an open eye; and one great ornament of this beautiful structure is in the arrangement of internal columns placed in the front of niches, composed of antae, or pier-formed ends of walls, to carry an entablature round under an attic on which the cupola rests. The Romans also adopted coupled columns, broken and recessed entablatures, and pedestals, which are considered blemishes.

They again paid more attention to the interior than to the exterior decoration of their palaces and baths,--as we may infer from the ruins of Hadrian's villa at Tivoli and the excavations of Pompeii.

The pediments (roof-angles) used in Roman architectural works are steeper than those made by the Greeks, varying in inclination from eighteen to twenty-five degrees, instead of fourteen. The mouldings are the same as the Grecian in general form, although they differ from them in contour; they are less delicate and graceful, but were used in great profusion. Roman architecture is overdone with ornament, every moulding carved, and every straight surface sculptured with foliage or historical subjects in relief. The ornaments of the frieze consist of foliage and animals, with a variety of other things. The great exuberance of ornament is considered a defect, although when applied to some structures it is exceedingly beautiful. In the time of the first Caesars Roman architecture had, from the huge size of the buildings, a character of grandeur and magnificence. Columns and arches appeared in all the leading public buildings,--columns generally forming the external and arches the internal construction. Fabric after fabric arose on the ruins of others. The Flavii supplanted the edifices of Nero, which ministered to debauchery, by structures of public utility.

The Romans invented no new principle in architecture, unless it be the arch, which was known, though not practically applied, by the a.s.syrians, Egyptians, and Greeks. The Romans were a practical and utilitarian people, and needed for their various structures greater economy of material than was compatible with large blocks of stone, especially for such as were carried to great alt.i.tudes. The arch supplied this want, and is perhaps the greatest invention ever made in architecture. No instance of its adoption occurs in the construction of Greek edifices before Greece became a part of the Roman empire. Its application dates back to the Cloaca Maxima, and may have been of Etrurian invention. Some maintain that Archimedes of Sicily was the inventor of the arch; but to whomsoever the glory of the invention is due, it is certain that the Romans were the first of European nations to make a practical application of its wonderful qualities. It enabled them to rear vast edifices with the humblest materials, to build bridges, aqueducts, sewers, amphitheatres, and triumphal arches, as well as temples and palaces. The merits of the arch have never been lost sight of by succeeding generations, and it is an essential element in the magnificent Gothic cathedrals of the Middle Ages. Its application extends to domes and cupolas, to floors and corridors and roofs, and to various other parts of buildings where economy of material and labor is desired. It was applied extensively to doorways and windows, and is an ornament as well as a utility. The most imposing forms of Roman architecture may be traced to a knowledge of the properties of the arch, and as brick was more extensively used than any other material, the arch was invaluable. The imperial palace on Mount Palatine, the Pantheon (except its portico and internal columns), the temples of Peace, of Venus and Rome, and of Minerva Medica, were of brick. So were the great baths of t.i.tus, Caracalla, and Diocletian, the villa of Hadrian, the city walls, the villa of Mecaenas at Tivoli, and most of the palaces of the n.o.bility,--although, like many of the temples, they were faced with stone. The Colosseum was of travertine, a cheap white limestone, and faced with marble. It was another custom to stucco the surface of brick walls, as favorable to decorations. In consequence of the invention of the arch, the Romans erected a greater variety of fine structures than either the Greeks or Egyptians, whose public edifices were chiefly confined to temples. The arch entered into almost every structure, public or private, and superseded the use of long stone-beams, which were necessary in the Grecian temples, as also of wooden timbers, in the use of which the Romans were not skilled, and which do not really pertain to architecture: an imposing edifice must always be constructed of stone or brick. The arch also enabled the Romans to economize in the use of costly marbles, of which they were very fond, as well as of other stones. Some of the finest columns were made of Egyptian granite, very highly polished.

The extensive application of the arch doubtless led to the deterioration of the Grecian architecture, since it blended columns with arcades, and thus impaired the harmony which so peculiarly marked the temples of Athens and Corinth; and as taste became vitiated with the decline of the empire, monstrous combinations took place, which were a great fall from the simplicity of the Parthenon and the interior of the Pantheon.

But whatever defects marked the age of Diocletian and Constantine, it can never be questioned that the Romans carried architecture to a perfection rarely attained in our times. They may not have equalled the severe simplicity of their teachers the Greeks, but they surpa.s.sed them in the richness of their decorations, and in all buildings designed for utility, especially in private houses and baths and theatres.

The Romans do not seem to have used other than semicircular arches. The Gothic, or Pointed, or Christian architecture, as it has been variously called, was the creation of the Middle Ages, and arose almost simultaneously in Europe after the first Crusade, so that it would seem to be of Eastern origin. But it was a graft on the old Roman arch, in the curve of the ellipse rather than the circle.

Aside from this invention of the arch, to which we are indebted for the most beautiful ecclesiastical structures ever erected, we owe everything in architecture to the Greeks and Romans. We have found out no new principles which were not known to Vitruvius. No one man was the inventor or creator of the wonderful structures which ornamented the cities of the ancient world. We have the names of great architects, who reared various and faultless models, but they all worked upon the same principles, and these can never be subverted; so that in architecture the ancients are our schoolmasters, whose genius we revere the more we are acquainted with their works. What more beautiful than one of those grand temples which the cultivated heathen Greeks erected to the worship of their unknown G.o.ds!--the graduated and receding stylobate as a base for the fluted columns, rising at regular distances in all their severe proportion and matchless harmony, with their richly carved capitals supporting an entablature of heavy stones, most elaborately moulded and ornamented with the figures of plants and animals; and rising above this, on the ends of the temple, or over a portico several columns deep, the pediment, covered with chiselled cornices, with still richer ornaments rising from the apices and at the feet, all carved in white marble, and then spread over an area larger than any modern churches, making a forest of columns to bear aloft those ponderous beams of stone, without anything tending to break the continuity of horizontal lines, by which the harmony and simplicity of the whole are regulated! So accurately squared and nicely adjusted were the stones and pillars of which these temples were composed, that there was scarcely need even of cement. Without noise or confusion or sound of hammers did those temples rise, since all their parts were cut and carved in the distant quarries, and with mathematical precision. And within the cella, nearly concealed by surrounding columns, were the statues of the G.o.ds, and the altars on which incense was offered, or sacrifices made. In every part, interior and exterior, do we see a matchless proportion and beauty, whether in the shaft or the capital or the frieze or the pilaster or the pediment or the cornices, or even the mouldings,--everywhere grace and harmony, which grow upon the mind the more they are contemplated. The greatest evidence of the matchless creative genius displayed in those architectural wonders is that after two thousand years, and with all the inventions of Roman and modern artists, no improvement has been made; and those edifices which are the admiration of our own times are deemed beautiful as they approximate the ancient models, which will forever remain objects of imitation. No science can make two and two other than four; no art can make a Doric temple different from the Parthenon without departing from the settled principles of beauty and proportion which all ages have indorsed. Such were the Greeks and Romans in an art which is one of the greatest indices of material civilization, and which by them was derived from geometrical forms, or the imitation of Nature.

The genius displayed by the ancients in sculpture is even more remarkable than their skill in architecture. Sculpture was carried to perfection only by the Greeks; but they did not originate the art, since we read of sculptured images from the remotest antiquity. The earliest names of sculptors are furnished by the Old Testament. a.s.syria and Egypt are full of relics to show how early this art was cultivated. It was not carried to perfection as early, probably, as architecture; but rude images of G.o.ds, carved in wood, are as old as the history of idolatry.
