The rise seems to have been less in former times than now. In the days of Moeris it is said that 8 cubits were sufficient; 15 or 16 were required in the time of Herodotus, 456 B. C. At the present day 18 cubits is considered the lowest inundation at Cairo.
Hear the Father of history : —
One fact which I learnt of the priests is to me a strong evidence of the origin of the country.
They said to me that, when Moeris was king, the Nile overflowed all Egypt below Memphis, as soon as it rose so little as 8 cubits.
Now Moeris had not been dead 900 years at the time when I heard this of the priests; yet at the present day, unless the river rise 15 or 16 cubits, it d

The periodical rise of the Nile commences about the first of June, continues for three months, remains stationary about twelve days, and then as gradually subsides.
The rise is greatest in Upper Egypt, and less toward the month of the river.
The rise was less at former periods than now. In the time of Moeris, it is said that eight cubits were sufficient; fifteen or sixteen were required in the time of Herodotus, 456 B. C. At the present day eighteen cubits is considered the lowest inundation at Cairo.
In the time of Pliny (A. D. 70) twelve cubits were a famine, thirteen scarcity, fifteen safety, sixteen plenty.
At the present day eighteen cubits in the lowest, and at this hight the canals are cut, and distribution commences; nineteen cubits are tolerable, twenty adequate, twenty-one excellent, twenty-two abundant, and twenty-four ruinous to the houses and stores which are overflowed thereby.
