Now the country lying between the Linant Lake Mœris and the Birket-el-Qurûn was said to be irrigated from this lake. Imagine the state of insecurity for this tract of sloping land, with a huge reservoir of water standing 13 metres above that part which lies along the north face of the lake, and more than this above the part along the west face. When one considers, too, that there must have been passages for irrigation through this bank, and how dangerous such an arrangement would be, it is scarcely credible that the collection of thriving towns included in the Arsinoïte nome would have grown in such a perilous situation. Imagine, also, the infiltration that would result on the lands along the faces of this lake. According to the theory, the Lake Linant, not being of sufficient dimensions itself to regulate the Nile, was to pass on the surplus into Birket-el-Qurûn by escapes on the two main drainage lines. Thus the poor fools, who had settled themselves on the strip between the two lakes, would be in danger of inundation, both from above and below, and would be in as bad a plight as Pharaoh’s horsemen in the Red Sea. A diagrammatic section of the Fayûm (Plate VIII.), as it would have been when in this unhappy state (fortunately imaginary), will make the situation perhaps plainer. The diagram, by exaggerating the vertical dimensions with reference to the horizontals, emphasises the danger of the situation and shows how improbable it is that such a theory could be true. [Illustration: PLATE VIII. SKETCH OF THE FAYÛM From Lahûn through Biahmu to Lake Qurûn through the highest plateau, showing Linant’s supposed Lake.] It should be noted that the Linant Lake itself covers the richest land of the Fayûm, namely, that which, being near the first point of expansion of the inflow into the depression, had received the richest deposit during the time that the Fayûm was forming previous to the creation of Lake Mœris; and, further, it should be remarked that the remainder of the best land round the margins and for a considerable distance from the Linant lake banks would have been probably ruined by infiltration. Where, then, should we find the rich lands of the Arsinoïte Nome, so famous for their produce? M. Linant objects (and there is, doubtless, weight in this objection) to the theory of the submergence of the Fayûm by a sufficient elevation of the waters of the Birket-el-Qurûn, that there would be no place for the Arsinoïte Nome; and he thinks that by his theory he has found a place for it between the two rival lakes. The ancient Egyptians, who lived before our era, must have had prodigious faith in their protecting deities, or in their department of public works, if they took up their abode behind Linant’s bank.
