The columns of the portico carried beams, on the frieze of which the following inscription in large letters has been placed: M·AGRIPPA·L·F·COS·TERTIUM·FECIT. Another inscription below this one, in smaller characters, states the building to have been restored by Septimius Severus and Caracalla. The beams carry a large pediment, originally adorned with groups of statues representing Jupiter's victories over the Gigantes. Behind and above this gable rises a second one of the same proportions, serving as an ornament of the projecting wall which connects the round building with the portico. The roof of the portico was supported by beams made of brass. According to the drawing of Serlio, these beams were not massive, but consisted of brass plates riveted together into square pipes—a principle frequently applied by modern engineers on a larger scale in building bridges, etc. Unfortunately, the material of the roof, barring some of the large rivets, has been used by Pope Urban VIII. for guns and various ornaments of doubtful taste in St. Peter's Cathedral. The large columns carrying the ugly tabernacle on the grave of St. Peter are one of the results of this barbarous spoliation. The old door, also made of brass, which leads from the portico into the interior has, on the contrary, been preserved. The outer appearance of the round building is simple and dignified. It most likely was originally covered with stucco and terra-cotta ornaments, of which, however, little remains at present; but the simple bricks, particularly in the upper stripes, where the insertion of the vault becomes visible, look, perhaps, quite as beautiful as the original coating. The whole cylinder of masonry is divided into three stripes by means of cornices, which break the heaviness of the outline, the divisions of the inner space corresponding to those of the outer surface. The first of these stripes is about forty feet high, and rests on a base of Travertine freestone. It consists of simple horizontal slabs of stone, broken only by doors which lead to chambers built in the thickness of the wall between the niches. It corresponds to the columns forming the first story of the interior, the two cornices, in and outside, being on a level. The second stripe, about thirty feet in height, answers to the second story of the interior, where the semicircular arches of the niches are situated. The horizontal stone layers outside are accordingly broken by large double arches, destined to balance the vaults in the interior. They alternate with smaller arches, thus forming a decoration of the exterior at once dignified and in harmony with the general design of the building. The two cornices in and outside are again on a level. The third stripe corresponds to the cupola, the tension of which is equal to 140 feet. The outer masonry reaches up to about a third of its height, from which point the cupola proper begins to rise in seven mighty steps.
The height of the dome is equal to the diameter of the cylindrical building, 132 feet, which adds to the sober and harmonious impression of the whole building. The lower of the above-mentioned interior stories is adorned with columns and pilasters, the latter of which enclosed the niches. Eight of these columns, over thirty-two feet in height, are monoliths of giallo antico—a yellow kind of marble beautifully veined, and belonging to the most valuable materials used by ancient architects. Six other columns are made of a kind of marble known as pavonazzetto; by an ingenious mode of coloring these columns are made to harmonize with those consisting of the rarer material. Above the first lies a second lower story, the architectural arrangements of which may be recognized from Adler's ingenious attempt at reconstruction. Its original decoration consisted of tablets of colored marble, the effect being similar to that of a sequence of narrow pilasters. This original decoration has later been changed for another. Above the chief cornice which crowns this story, and at the same time terminates the circular walls, rises the cupola, divided into five stripes, each of which contains twenty-five "caskets" beautifully worked and in excellent perspective. In the center at the top is an opening, forty feet in diameter, through which the light enters the building. Near this opening a fragment has been preserved of the bronze ornamentation which once seems to have covered the whole cupola. Even without these elegant decorations the building still excites the spectator's admiration, as one of the masterpieces of Roman genius.
HALF-SECTION OF THE PANTHEON.[ToList]
Obelisks were in Egypt commemorative pillars recording the style and the title of the king who erected them, his piety, and the proof he gave of it in dedicating those monoliths to the deity whom he especially wished to honor. They are made of a single block of stone, cut into a quadrilateral form, the width diminishing gradually from the base to the top of the shaft, which terminates in a small pyramid (pyramidion). They were placed on a plain square pedestal, but larger than the obelisk itself. Obelisks are of Egyptian origin. The Romans and the moderns have imitated them, but they never equaled their models.
Egyptian obelisks are generally made of red granite of Syene. There are some, however, of smaller dimensions made of sandstone and basalt. They were generally placed in pairs at the entrances of temples, on each side of the propyla. The shaft was commonly ten diameters in height, and a fourth narrower at the top than at the base. Of the two which were before the palace of Luxor at Thebes, one is seventy-two feet high, and six feet, two inches wide at the base; the other is seventy-seven feet high, and seven feet, eight inches wide. Each face is adorned with hieroglyphical inscriptions in intaglio, and the summit is terminated by a pyramid, the four sides of which represent religious scenes, also accompanied by inscriptions. The corners of the obelisks are sharp and well cut, but their faces are not perfectly plane, and their slight convexity is a proof of the attention the Egyptians paid to the construction of their monuments. If their faces were plane they would appear concave to the eye; the convexity compensates for this optical illusion. The hieroglyphical inscriptions are in a perpendicular line, sometimes there is but one in the middle of the breadth of the face, and often there are three. The inscription was a commemoration by the king who had the temple or palace built before which the obelisk was placed. It contained a record stating the houses and titles which the king who erected, enlarged, or gave rich presents to a temple, had received in return from the priesthood, and setting forth, for instance, that Rameses was the lord of an obedient people, and the beloved of Ammon. Such is the subject of the inscription which is in the middle of each face of the obelisks; and though the name of the same king and the same events are repeated on the four sides, there exists in the four texts, when compared, some difference, either in the invocation to the particular divinities or in the titles of the king. Every obelisk had, in its original form, but a single inscription on each face, and of the same period of the king who had erected it; but a king who came after him, adding a court, a portico, or colonnade to the temple or palace, had another inscription relative to his addition, with his name engraved on the original obelisk; thus, every obelisk adorned with many inscriptions is of several periods. The pyramidion which terminates them generally represents in its sculptures the king who erected the obelisk making different offerings to the principal deity of the temple, and to other divinities. Sometimes also the offering is of the obelisk itself. The short inscriptions of the pyramidion bear the oval of the king and the name of the divinity. By these ovals can be known the names of the kings who erected the obelisks still existing, whether in Egypt or elsewhere. The largest obelisk known is that of St. John Lateran, Rome. It was brought from Heliopolis to Alexandria by the emperor Constantine, and was conveyed to Rome by Constantius, who erected it in the Circus Maximus. The height of the shaft is 105 feet, 7 inches. The sides are of unequal breadth at the base, two measure nine feet, eight and one-half inches, the other two only nine feet. It bears the name of Thohtmes III. in the central, and that of Thohtmes IV. in the lateral lines, kings of the eighteenth dynasty, in the fifteenth century B.C. The two obelisks at Luxor were erected by the king Rameses II., of the nineteenth dynasty, 1311 B.C. (Wilkinson). One of these has been taken to Paris. The obelisk of Heliopolis bears the name of Osirtasen I., 2020 B.C. (Wilkinson), and is consequently the most ancient. It is about sixty-seven feet high. The obelisks at Alexandria were brought from Heliopolis about 2,000 years ago. The one that was lying in the sand, and the smaller of the two, was removed to London some years ago, and the other, which was still standing, was presented to the United States by Ismail Pasha, father of the present Khedive. This monument of antiquity is an inestimable treasure to our country. It bears the name of Thohtmes III. In the lateral lines are the ovals of Rameses the Great. It is of red granite of Syene. It bears the name of Cleopatra's Needle, is about seventy feet high, with a diameter at its base of seven feet, seven inches. We can hardly appreciate that we should have standing in New York a relic so ancient—a column upon which Moses and Aaron looked, and doubtless read its hieroglyphic inscription; that Rameses the Great (Sesostris) had his knightly banner carved upon it; that Darius, Cambyses, Alexander the Great, the Ptolemies, Julius Cæsar, Cleopatra, Mark Antony and Augustus knew it; that it was equally known and beheld of Pythagoras, Herodotus and Strabo; that a long procession of the most illustrious characters of the middle ages have passed before it, from the days of Clement and Anastasius to those of Don John of Austria; and, finally, that it was the first herald of Egypt to Napoleon and Mohammed Ali. A monument like this will truly be cherished by every citizen. The obelisk of the Piazza del Popolo claims great interest, as it also stood before the Temple of the Sun at Heliopolis. Lepsius attributes it to Meneptha. It was removed to Rome by Augustus, B.C. 19, to ornament the Circus Maximus. The obelisk in front of St. Peter's was brought to Rome by Caligula, and placed on the Vatican in the Circus of Caligula. It is about eighty-three feet high. There are several other Egyptian obelisks in Rome. Nothing can afford a greater idea of the skill of the Egyptians, and of their wonderful knowledge of mechanism, than the erection of these monoliths.
