Writing of the Arsinoïte Nome he says, “This province is the most remarkable of all in appearance, natural properties, and embellishment. It grows olive-trees which bear fruit. It produces wine in abundance, corn, pulse, and a great variety of other grains. . . .
“It has also a remarkable lake called the Lake of Mœris, large enough to be called a sea, and resembling the open sea in colour; its shores are also similar in appearance to sea-beaches, whence we may suspect a community of nature between them and the district about Ammon. For they are in fact not far distant from one another or from Parætonium, and as there is good reason to suppose that the latter temple formerly stood on the sea-shore, so also this district must formerly have been littoral. Lower Egypt and the parts towards the Serbonian Lake were then covered by the sea, perhaps connected with the Red Sea by Heroöpolis and the Elanitic Gulf. . . .
“Thus, the Lake of Mœris is, from its size and depth, capable of receiving the overflow of the Nile at its rising, and preventing the flooding of houses and gardens; when the river falls, the lake again discharges the water by a canal at both orifices, and it is available for irrigation. There are regulators at both ends of the canal for controlling the inflow and outflow. Near these is an immense stone Labyrinth, a work comparable with the Pyramids; and the tomb of the king who constructed it. . . .
“Sailing 100 furlongs further one comes to the city Arsinoë, formerly called Crocodilopolis.”
Diodorus Siculus, Book I. Chap. LI. (about B.C. 20).
“He (King Mœris) dug a lake 600 furlongs above the city (Memphis), which is amazingly useful and incredibly large. Its circumference is said to be 3600 furlongs, and its depth in most parts 50 fathoms. . . . For as the rising of the Nile is irregular, and the fertility of the country depends on its uniformity, he dug the lake for the reception of the superfluous water. And he constructed a canal from the river to the lake 80 furlongs in length and 300 feet in breadth. Through this he admitted or let out water as required, the mouth being opened or closed by an elaborate and costly process (for it cost not less than 50 talents whenever any one wished to open or close the mechanism). This lake has continued to serve the Egyptians for this purpose down to our own times, and is called the Lake of Mœris after its constructor. When the king dug it he left in the centre a place on which he built a tomb and two pyramids, one for himself and the other for his wife, a furlong in height, expecting thus to leave an immortal reputation for his benefactions. The revenue of the fisheries in the lake he gave to his wife for her allowance for perfumes and cosmetics generally; they brought in a sum of a talent of silver daily; for there are said to be twenty-two kinds of fish in it, and the quantity taken is so large that the numerous hands engaged in the salt-curing industry can hardly keep pace with the work.”
Pliny, Nat. Hist., Book V. Chap. 9 (A.D. 50-70).
“Between the nomes of Arsinoë and Memphis was a lake, 250 miles (i.e. Roman miles) in circumference; or, as Mucianus tells us, 450 miles in circumference and 50 paces in depth, artificially constructed, called the Lake of Mœris, from the king who made it. Seventy-two miles distant from this is Memphis, formerly the capital of Egypt.”
Pliny, Nat. Hist., Book XXXVI. Chap. 16.
“There were two other pyramids near the Lake of Mœris, which is a large excavation.”
