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 accumulated by private persons.

The earliest monuments of enduring magnificence were the temples of powerful priests and the palaces of kings; and in Egypt and Assyria 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 principal 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, massive, 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 massive 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 nobly 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 principal 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 assumes 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 mass 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 circumference, and in which were one hundred gates of brass, 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 façades 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 balustrade, 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 basement 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.
