Although there are still minor differences of opinion with regard to the details of Egyptian chronology, still the divergences between the various systems proposed are gradually narrowing in extent. The sequence of events is certain, and accepted by all. The initial date, and the adjustments depending on it, are alone in dispute. The truth is that every subsequent step in the investigation has tended more and more to prove the correctness of the data furnished by the lists of Manetho, and the only important question is, “what is Manetho?” His work is lost. The only real extracts we have from the original are those in ‘Josephus contra Apion.’ The lists in Eusebius and Syncellus or Africanus have avowedly been adjusted to suit preconceived theories of Biblical chronology; but on the whole a great preponderance of evidence seems in favour of assuming that he really intended to fix the year 3906 as the initial year of the reign of Menes,[[24]] or some year within a very short distance of that date. Some years ago this would have seemed to suffice, but so many new monuments have been disinterred of late, so many new names of kings added to our lists, that the tendency is now rather to extend than to contract this limit of duration.

Be this as it may, what we really do know absolutely is that there was an old kingdom of pyramid-builders, comprising the first ten dynasties of Manetho, who reigned at Memphis. These, after a period of decadence, were superseded by kings of a different race coming from the south; and that these, after a short period of glory, were conquered by an Asiatic race of hated Shepherd kings.

After five centuries of foreign domination, the Shepherds in their turn were driven out, and the new kingdom founded. This, after witnessing the glories of the 18th and 19th dynasties, declined during the next seven dynasties till they were struck down by the Persian Cambyses.

A third period of architectural magnificence arose with the Ptolemys, and was continued by the Cæsars on nearly the same scale of magnificence as the second kingdom; but wanting its exuberant nationality, and far below the quiet grandeur of the earlier epoch.

In counting backwards the dates of these dynasties, the first authentic synchronism we meet with is that of Shishak, the first king of the 22nd dynasty, contemporary with Rehoboam, about 970 B.C.

The next is the Exode of the Jews, which took place 1312 B.C., under the reign of Meneptah II., the fourth king of the 19th dynasty of Manetho. Many would place it earlier, but none probably would bring that event down to a more modern date.

From this date Josephus tells us that Manetho counted 518 years to the expulsion of the Shepherds, and 511 for the duration of their sojourn in Egypt,[[25]] we thus get back to 2340 for the first year of Salatis. There then remain only fifteen centuries and a half, in which we have to arrange the two great Theban dynasties (the 11th and 12th), which reigned for more than two centuries over the whole of Egypt; while the 12th seems to have extended some distance into the period occupied by the Shepherds. We are thus left with little more than 1300 years over which to spread the ten first dynasties, notwithstanding that some 60 or 70 of their royal sepulchral pyramids still adorn the banks of the Nile; and we have many names to which no tombs can be attached, and many pyramids may have perished during the 5000 years which have elapsed since the greater number of them were erected.

Long as these periods may to some appear, they are certainly the shortest that any one familiar with the recent progress of Egyptian research would be willing to assign to them. But in whatever light they may be viewed, they sink into utter insignificance when compared with the periods that must have elapsed before Egypt could have reached that stage of civilisation in which we find her when her existence first dawns upon us. If one point in Egyptian history is proved with more certainty than another, it is that the great Pyramids of Gizeh were erected by the kings of the 4th dynasty: and it seems impossible to find room for the now ascertained facts of Egyptian chronology, unless we place their erection between 3000 and 3500 years before the Christian era.

No one can possibly examine the interior of the Great Pyramid without being struck with astonishment at the wonderful mechanical skill displayed in its construction. The immense blocks of granite brought from Syene—a distance of 500 miles—polished like glass, and so fitted that the joints can hardly be detected. Nothing can be more wonderful than the extraordinary amount of knowledge displayed in the construction of the discharging chambers over the roof of the principal apartment, in the alignment of the sloping galleries, in the provision of ventilating shafts, and in all the wonderful contrivances of the structure. All these, too, are carried out with such precision, that, notwithstanding the immense superincumbent weight, no settlement in any part can be detected to the extent of an appreciable fraction of an inch. Nothing more perfect, mechanically, has ever been erected since that time; and we ask ourselves in vain, how long it must have taken before men acquired such experience and such skill, or were so perfectly organised, as to contemplate and complete such undertakings.

Around the base of the pyramid are found numerous structural tombs, whose walls bear the cartouche of the same king—Khufu—whose name was found by Colonel Howard Vyse in one of the previously unopened chambers of the Great Pyramid.[[26]] These are adorned with paintings so numerous and so complete, as to enable us to realise with singular completeness the state of Egyptian society at that early period.
