It was for similar motives that the Egyptians did not, as a rule, care to use very large stones. Their obelisks and colossal statues prove that they knew how to quarry and raise blocks of enormous size, but they never made those efforts except when they had good reason to do so. They did not care to exhaust themselves with dragging huge stones up on to their buildings, where they would ever after be lost to sight under the stucco. In the most carefully built Theban edifices the average size of the stones hardly exceeds that of the materials which are used by our modern architects. A single course was from 30 to 38 inches high, and the length of the blocks varied between 5 feet and rather more than 8. In the great pylon of Karnak the lintel over the doorway is a stone beam more than 25 feet long. In the hypostyle hall the architraves of the central aisle are at least 29 feet long.[59]
It is said that some attain a length of nearly 32 feet.

The Egyptian architect was therefore quite ready to use monoliths of exceptional size for the covering of voids when they were necessary, but he did not wantonly create that necessity, as those of other nations have often done. Most of the travellers who visit Egypt expect to find huge monolithic shafts rearing their lofty heads on every side, and their surprise is great when they are told that the huge columns of the hypostyle halls are not cut from single blocks. Their first illusion is fostered by the large number of monolithic granite columns which are found at Erment, at Antinoe, at Cairo, in most of the modern Egyptian mosques. When they arrive at Thebes they discover their error. At Karnak and at Luxor, at Medinet-Abou and in the Ramesseum, the columns are made up of drums placed one upon another.
In many cases even these drums are not monolithic, but consist of several different stones. Under the Roman domination the Egyptians deliberately chose to make their columns of single stones, and most of those which are of exceptional size date from that late epoch. We know but one case to which these remarks do not apply; we mean that of the monolithic supports in the chambers of the labyrinth which were mentioned by Strabo, and discovered, as some believe, by Lepsius.[60]
We are told by that traveller that they were of granite, but he only saw them when broken. Strabo says that the chambers were roofed in with slabs of such a size that they amazed every one who saw them, and added much to the effect which that famous structure was otherwise calculated to produce. Prisse describes and figures a column of red granite which he ascribes to Amenophis III., and which, according to him, was brought from Memphis to Cairo. Without the base which, as given in his drawing, must be a restoration, it is 13 feet 8-1/2 inches high, including the capital.[61] It belongs to the same kind of pillar as those observed by Lepsius in the Fayoum. In a painting in one of the Gournah tombs, three workmen are shown polishing a column exactly similar to that figured by Prisse, with the single exception that its proportions are more slender (Fig. 42). Monolithic columns of red granite have been discovered to the west of the present city of Alexandria which are nearly 22 feet high. Their capitals are imitated from truncated lotus-buds, like that in Fig. 42.

It would seem, then, that monolithic columns were in fashion during the early centuries of the second Theban empire, but that, in later times, the general custom was to build up columns, sometimes for their whole height, of moderately sized, and sometimes of very small stones (Fig. 17).[62]
[62] The columns at Luxor are constructed in courses. The joints of the stone are worked carefully for only about a third of their whole diameter. Their centres are slightly hollowed out and filled in with a mortar of pounded brick which has become friable. (_Description de l"egypte_, _Antiquites_, vol. ii. p.
384.)

To all that concerns the quality of the building similar remarks may be applied. We have mentioned a few examples of careful and scientific construction, but, as a rule, Egyptian buildings were put together in a fashion that was careless in the extreme.[63] The foundations were neither wide enough nor deep enough. It is not until we come to the remains of the Ptolemaic period, such as the temples at Edfou and Denderah, that we discover foundations sinking 16 or 18 feet into the ground. The Pharaonic temples were laid upon the surface rather than solidly rooted in the soil. Mariette attributes the destruction which has overtaken the temples at Karnak less to the violence of man or to earthquakes than to inherent faults of construction, and to the want of foresight shown by their architects in not placing them at a sufficient elevation above the inundations. For many centuries the waters of the Nile have reached the walls of the temples by infiltration, and have gradually eaten away the sandstone of which they are composed. "Similar causes produce similar effects, and the time may be easily foreseen when the superb hypostyle hall will yield to the attacks of its enemy, and its columns, already eaten through for three quarters of their thickness, will fall as those of the western court have fallen."[64]
[63] See p. 29, vol. i. (Note 1) and p. 170. The engineers who edited the _Description_ make similar remarks with regard to Karnak. (_Antiquites_, vol. ii. pp. 414 and 500.)
[64] MARIETTE, _Itineraire_, p. 179. The pavement of the great temple is now about six feet below the general level of the surrounding plain.
At the time when Karnak was built there were in the country buildings which were from ten to fifteen centuries old, to which the architects of the time might have turned for information upon doubtful points. In them the gradual rising of the valley level must have been clearly shown. This want of foresight need cause us, however, no great surprise; but it is otherwise with the carelessness of the architects in arranging their plans, and in failing to compel the workmen to follow those plans when made. "Except in a few rare instances," says Mariette, "the Egyptian workman was far from deserving the reputation he has gained for precision and care in the execution of his task.
Only those who have personally measured the tombs and temples of Egypt know how often, for instance, the opposite walls of a single chamber are unequal in height."[65]
[65] MARIETTE, _Les Tombes de l"Ancien Empire_, p. 10.
The custom of building as fast as possible and trusting to the painted decoration for the concealment of all defects, explains the method most usually taken to keep the materials together. The system of using large dressed stones made the employment of mortar unnecessary. The Greeks, who used the same method and obtained from it such supreme effects, put no mortar between their stones. Sometimes they were held together by tenons of metal or wood, but the builder depended for cohesion chiefly upon the way in which his materials were dressed and fixed. The two surfaces were so intimately allied that the points of junction were almost invisible. The Egyptians were in like manner able to depend upon the _vis inertiae_ of their materials for the stability of their walls, and their climate was far better fitted even than that of Greece for the employment of those wooden or metal tenons which would prevent any slipping or settlement in the interior of the masonry. The dangers attending such methods of fixing would thus be reduced to a minimum. "In consequence of a dislocation in the walls caused by the insufficiency of the foundations, it is possible, at several points of the temple walls at Abydos, to introduce the arm between the stones and feel the sycamore dovetails still in place and in an extraordinary state of preservation. A few of these dovetails have been extracted, and, although walled in for eternity so far as the intentions of the Egyptians were concerned, they bear the royal ovals of Seti I., the founder of the temple, the hieroglyphs being very finely engraved."[66]
[66] MARIETTE, _Abydos_, vol. i. p. 8.--_Catalogue general des Monuments d"Abydos_, p. 585. Similar tenons were found by the members of the _Inst.i.tut d"egypte_ in the walls of the great hall at Karnak (_Description de l"egypte, Antiquites_, vol. ii.
p. 442.--See also _Plates_, vol. ii. pl. 57, figs. 1 and 2). We took this ill.u.s.tration for our guide in compiling our diagram of Egyptian bonding in Fig. 69.
We see, then, that in many buildings the Egyptians employed methods which demanded no little patience, skill, and attention from the workman, but as a rule they preferred to work in a more expeditious and less careful fashion. They used a cement made of sand and lime; traces of it are everywhere found, both in the ruins of Thebes and in the pyramids, between the blocks of limestone and sandstone.[67] Still more did bricks require the use of mortar, which in their case was often little more than mud.

Among the processes made use of for the construction of the great temple at Thebes there was one which bore marks of the same tendency.
Mariette tells us that traces exist in the front of the great temple of a huge inclined plane made of large crude bricks. This incline was used for the construction of the pylon. The great stones were dragged up its slopes, and as the pylon grew, so did the ma.s.s of crude brick.
When the work was finished the bricks were cleared away, but the internal face of the pylon still bears traces of their position against it. This work was carried out, according to Mariette, under the Ptolemies,[68] but the primitive method of raising the stones must have come down from times much more remote.[69]

The first travellers who visited Egypt in modern times were struck with the colossal size of some buildings and of a few monoliths, and jumped to the conclusion that the Egyptians were peculiarly skilled in mechanics and engineering. They declared, and it has been often repeated, that this people possessed secrets which were afterwards lost; that many an Archimedes flourished among them who excelled his Syracusan successor. All this was a pure illusion. Their only machines seem to have been levers and perhaps a kind of elementary crane.[70]
The whole secret of the Egyptians consisted in their unlimited command of individual labour, and in the unflinching way in which they made use of it. Mult.i.tudes were employed upon a single building, and kept to their work by the rod of the overseer until it was finished. The great monoliths were placed upon rafts at the foot of the mountains in which they were quarried, and floated during the inundation by river and ca.n.a.l to a point as near as possible to their destined sites. They were then placed upon sledges to which hundreds of men were harnessed, and dragged over a well-oiled wooden causeway to their allotted places. Fig. 43, which is taken from a hypogeum of the twelfth dynasty, gives an excellent idea of the way in which these ma.s.ses of granite were transported. In this picture we see one hundred and seventy-two men arranged in pairs and, to use a military term, in four columns, dragging the sledge of a huge seated colossus by four ropes.[71] This colossus must have been about twenty-six feet high, if the pictured proportions between the statue and its convoy may be taken as approaching the truth. Upon the pedestal stands a man, who pours water upon the planks so that they shall not catch fire from the friction of so great a ma.s.s.[72] The engineer, who presides over the whole operation, stands upright upon the knees of the statue and "marks time" with his hands. At the side of the statue walk men carrying instruments of various kinds, overseers armed with rattans, and relays of men to take the place of those who may fall out of the ranks from fatigue. In the upper part we see a numerous troop of Egyptians carrying palm branches, who seem to be leading the procession.
[70] WILKINSON, _Manners and Customs_, etc., vol. ii. p. 309. In speaking of the pyramids Herodotus mentions what seems to have been a kind of crane, but he gives us no information as to its principle or arrangement (ii. 125).
[71] The painting in question dates from the reign of Ousourtesen II. and was found at El-Bercheh, a short distance above the ruins of Antinoe.
[72] The position of this man and the general probabilities of the case suggest perhaps, that his jar contains oil rather than water.--ED.
[Ill.u.s.tration: FIG. 43.--Transport of a colossus (Wilkinson, vol. ii., p. 305).]
From the first centuries of the monarchy blocks of granite of unusual size were thus transferred from place to place. We learn this from the epitaph of a high official named Una, who lived in the time of the sixth dynasty.[73] He recounts the services which he had rendered in bringing to Memphis the blocks of granite and alabaster required for the royal undertakings. Mention is made of buildings which had been constructed for the reception of monoliths. The largest of those buildings was 60 cubits (about 102 feet) long by 30 cubits wide. A little farther on we are told that one monolith required 3,000 men for its transport.
[73] BRUGSCH, _Histoire d"egypte_, vol. i. pp. 74 _et seq._
Thanks to their successful wars the great Theban princes had far wider resources at their command than their predecessors. Their architects could count upon the labour not only of the fellahs of the _corvee_, but also upon thousands of foreign prisoners. It was not astonishing, therefore, that the enterprises of the ancient empire were thrown into the shade. Neither were the Sait monarchs behind those of Thebes.
According to Herodotus the monolithic chapel which Amasis brought from the Elephantine quarries was 39 feet high by nearly 23 feet wide and 13 feet deep, outside measurement.[74] Taking the hollow inside into consideration such a stone must have weighed about 48 tons. Two thousand boatmen were occupied for three years in transporting this chapel from Elephantine into the Delta. Another town in the same region must have had a still larger monolithic chapel, if we are to believe the Greek historian"s account of it. It was square, and each of its sides measured 40 cubits (nearly 70 feet).[75]
[74] We agree with Wilkinson in taking for the height that which Herodotus calls the length. In all monuments of the kind the height is the largest measurement. Herodotus"s phrase is easily explained. The monolith appears to have been lying in front of the temple into which they had failed to introduce it. (?e?ta?
pa?? t?? ?s?d??, he says). Its height had thus become its length.
[75] HERODOTUS, ii. 155.
How did they set about erecting their obelisks? Upon this point we have no information whatever, either from inscriptions or from figured monuments. They may have used an inclined plane, to the summit of which the obelisk was drawn by the force of innumerable arms, and then lowered by the gradual removal of the part supporting its lower end. It is certain that the process was often a slow and laborious one. We know from an inscription that the obelisk which now stands before the church of San Giovanni Laterano in Rome was more than thirty-five years in the hands of the workmen charged with its erection in the southern quarter of Thebes.[76] Sometimes, however, much more rapid progress was made. According to the inscription on the base of the obelisk of Hatasu at Karnak, the time consumed upon it, from the commencement of work in the quarry to its final erection at Thebes, _was only seven months_.[77]
[76] The text in question is quoted in the notes contributed by Dr. BIRCH to the last edition of WILKINSON (vol. ii. p. 308, note 2). PLINY"S remarks upon the obelisks are intersprinkled with fabulous stories and contain no useful information (H. N., x.x.xvi. 14).
[77] PIERRET, _Dictionnaire d"Archeologie egyptienne_. (The dates upon which this a.s.sertion depends have been disputed. M.
CHABAS reads the inscription "from the first of Muchir in the year 16, to the last of Mesore in 17," making nineteen months in all, a period which is not quite so impossible as that ordinarily quoted.--ED.)
Whatever may have been their methods we may be sure that there was nothing complicated or particularly learned in them. The erection of the obelisks, like that of the colossal statues, must have been an affair merely of time and of the number of arms employed.
"One day," says Maxime du Camp, "I was sitting upon one of the architraves supported by the columns of the great hall at Karnak, and, glancing over the forest of stone which surrounded me, I involuntarily cried out: "But how did they do all this?""
"My dragoman, Joseph, who is a great philosopher, overheard my exclamation, and began to laugh. He touched my arm, and pointing to a palm tree whose tall stem rose in the distance, he said: "That is what they did it all with; a hundred thousand palm-branches broken over the backs of people whose shoulders are never covered, will create palaces and temples enough. Ah yes, sir, that was a bad time for the date trees; their branches were cut a good deal faster than they grew!" And he laughed softly to himself as he caressed his beard."
"Perhaps he was right."[78]

-- 4. _The Arch._
We have already said that among the Egyptians the arch was only of secondary importance; that it was only used in accessory parts of their buildings. We are compelled to return to the subject, however, because a wrong idea has generally been adopted which, as in the case of the monoliths, we must combat evidence in hand. The extreme antiquity of the arch in Egypt is seldom suspected.
It was an article of faith with the architects of the last century that the arch was discovered by the Etruscans. The engineers of the French expedition did not hesitate to declare every arch which they found in Egypt to be no older in date than the Roman occupation. But since the texts have been interpreted it has been proved that there is more than one arch in Egypt which was constructed not only as early as the Ptolemies, but even under the Pharaohs. Wilkinson mentions brick arches and vaults bearing the names of Amenophis I., and Thothmes III.
at Thebes, and judging from the paintings at Beni-Ha.s.san, he is inclined to believe that they understood the principle as early as the twelfth dynasty.[79]
