The southern line of Egypt only just touches the tropics; still the climate, influenced by the wide and hot deserts that hem the valley, is semi-tropical in character. The fruits of the tropics and the cereals of the temperate zone grow luxuriantly. Thus favored in climate as well as in the matter of irrigation, Egypt became in early times the granary of the East. To it less favored countries, when stricken by famine,—a calamity so common in the East in regions dependent upon the rainfall,—looked for food, as did the families of Israel during drought and failure of crops in Palestine.

DYNASTIES AND CHRONOLOGY.—The kings, or Pharaohs, that reigned in Egypt from the earliest times till the conquest of the country by Alexander the Great (332 B.C.), are grouped into thirty-one dynasties. Thirty of these we find in the lists of Manetho, an Egyptian priest who lived in the third century B.C., and who compiled a chronicle of the kings of the country from the manuscripts kept in the Egyptian temples.

We cannot assign a positive date to the beginning of the First Dynasty, chiefly because Egyptologists are at a loss to know whether to consider all the dynasties of Manetho's list as successive or in part contemporaneous. Thus, it is held by some scholars that several of these families were reigning at the same time in the different cities of Upper and Lower Egypt; while others think that they all reigned at different epochs, and that the sum of the lengths of the several dynasties gives us the true date of the beginning of the political history of the country. Accordingly, some place the beginning of the First Dynasty at about 5000 B.C., while others put it at about 3000 B.C. The constantly growing evidence of the monuments is in favor of the higher figures.

MENES, THE FIRST OF THE PHARAOHS.—Menes is the first kingly personage, shadowy and indistinct in form, that we discover in the early dawn of Egyptian history. Tradition makes him the founder of Memphis, near the head of the Delta, the site of which capital he secured against the inundations of the Nile by vast dikes and various engineering works. To him is ascribed the achievement of first consolidating the numerous petty principalities of Lower Egypt into a single state.

THE FOURTH DYNASTY: THE PYRAMID KINGS (about 2700 B.C.).—The kings of the Fourth Dynasty, who reigned at Memphis, are called the Pyramid builders. Kufu I., the Cheops of the Greeks, was the first great builder. To him we can now positively ascribe the building of the Great Pyramid, the largest of the Gizeh group, near Cairo; for his name has been found upon some of the stones,—painted on them by his workmen before the blocks were taken from the quarries.

The mountains of stone heaped together by the Pyramid kings are proof that they were cruel oppressors of their people, and burdened them with useless labor upon these monuments of their ambition. Tradition tells how the very memory of these monarchs was hated by the people. Herodotus says that the Egyptians did not like even to speak the names of the builders of the two largest pyramids.

THE TWELFTH DYNASTY (about 2300 B.C.).—After the Sixth Dynasty, Egypt, for several centuries, is almost lost from view. When finally the valley emerges from the obscurity of this period, the old capital Memphis has receded into the background, and the city of Thebes has taken its place as the seat of the royal power.

The period of the Twelfth Dynasty, a line of Theban kings, is one of the brightest in Egyptian hhistory. Many monuments scattered throughout the country perpetuate the fame of the sovereigns of this illustrious house. Egyptian civilization is regarded by many as having during this period reached the highest perfection to which it ever attained.

THE HYSKOS, OR SHEPHERD KINGS (from about 2100 to 1650 B.C.).—Soon after the bright period of the Twelfth Dynasty, Egypt again suffered a great eclipse. Nomadic tribes from Syria crossed the eastern frontier of Egypt, took possession of the inviting pasture-lands of the Delta, and established there the empire of the Shepherd Kings.

These Asiatic intruders were violent and barbarous, and destroyed or mutilated the monuments of the country. But gradually they were transformed by the civilization with which they were in contact, and in time they adopted the manners and culture of the Egyptians. It was probably during the supremacy of the Hyksos that the families of Israel found a refuge in Lower Egypt. They received a kind reception from the Shepherd Kings, not only because they had the same pastoral habits, but also, probably, because of near kinship in race.
