Paragraph 108 108. Then Sesostris, having returned to Egypt and having taken vengeance on his brother, employed the multitude which he had brought in of those whose lands he had subdued, as follows:—these were they who drew the stones which in the reign of this king were brought to the temple of Hephaistos, being of very great size; and also these were compelled to dig all the channels which now are in Egypt; and thus (having no such purpose) they caused Egypt, which before was all fit for riding and driving, to be no longer fit for this from thenceforth: for from that time forward Egypt, though it is plain land, has become all unfit for riding and driving, and the cause has been these channels, which are many and run in all directions. But the reason why the king cut up the land was this, namely because those of the Egyptians who had their cities not on the river but in the middle of the country, being in want of water when the river went down from them, found their drink brackish because they had it from wells.
Paragraph 109 109. For this reason Egypt was cut up; and they said that this king distributed the land to all the Egyptians, giving an equal square portion to each man, and from this he made his revenue, having appointed them to pay a certain rent every year: and if the river should take away anything from any man's portion, he would come to the king and declare that which had happened, and the king used to send men to examine and to find out by measurement how much less the piece of land had become, in order that for the future the man might pay less, in proportion to the rent appointed: and I think that thus the art of geometry was found out and afterwards came into Hellas also. For as touching the sun-dial 91 and the gnomon 92 and the twelve divisions of the day, they were learnt by the Hellenes from the Babylonians.
