Of this land then, concerning which I have spoken, it seemed to myself
also, according as the priests said, that the greater part had been
won as an addition by the Egyptians; for it was evident to me that the
space between the aforesaid mountain-ranges, which lie above the city
of Memphis, once was a gulf of the sea, like the regions about Ilion
and Teuthrania and Ephesos and the plain of the Maiander, if it be
permitted to compare small things with great; and small these are in
comparison, for of the rivers which heaped up the soil in those
regions none is worthy to be compared in volume with a single one of
the mouths of the Nile, which has five mouths. Moreover there are
other rivers also, not in size at all equal to the Nile, which have
performed great feats; of which I can mention the names of several,
and especially the Acheloos, which flowing through Acarnania and so
issuing out into the sea has already made half of the Echinades from
islands into mainland. Now there is in the land of Arabia, not far
from Egypt, a gulf of the sea running in from that which is called the
Erythraian Sea, very long and narrow, as I am about to tell. With
respect to the length of the voyage along it, one who set out from the
innermost point to sail out through it into the open sea, would spend
forty days upon the voyage, using oars; and with respect to breadth,
where the gulf is broadest it is half a day's sail across: and there
is in it an ebb and flow of tide every day. Just such another gulf I
suppose that Egypt was, and that the one ran in towards Ethiopia from
the Northern Sea, and the other, the Arabian, of which I am about to
speak, tended from the South towards Syria, the gulfs boring in so as
almost to meet at their extreme points, and passing by one another
with but a small space left between. If then the stream of the Nile
should turn aside into this Arabian gulf, what would hinder that gulf
from being filled up with silt as the river continued to flow, at all
events within a period of twenty thousand years? indeed for my part I
am of the opinion that it would be filled up even within ten thousand
years. How, then, in all the time that has elapsed before I came into
being should not a gulf be filled up even of much greater size than
this by a river so great and so active? As regards Egypt then, I both
believe those who say that things are so, and for myself also I am
strongly of opinion that they are so; because I have observed that
Egypt runs out into the sea further than the adjoining land, and that
shells are found upon the mountains of it, and an efflorescence of
salt forms upon the surface, so that even the pyramids are being eaten
away by it, and moreover that of all the mountains of Egypt, the range
which lies above Memphis is the only one which has sand: besides which
I notice that Egypt resembles neither the land of Arabia, which
borders upon it, nor Libya, nor yet Syria (for they are Syrians who
dwell in the parts of Arabia lying along the sea), but that it has
soil which is black and easily breaks up, seeing that it is in truth
mud and silt brought down from Ethiopia by the river: but the soil of
Libya, we know, is reddish in colour and rather sandy, while that of
Arabia and Syria is somewhat clayey and rocky. The priests also gave
me a strong proof concerning this land as follows, namely that in the
reign of king Moiris, whenever the river reached a height of at least
eight cubits it watered Egypt below Memphis; and not yet nine hundred
years had gone by since the death of Moiris, when I heard these things
from the priests: now however, unless the river rises to sixteen
cubits, or fifteen at the least, it does not go over the land. I think
too that those Egyptians who dwell below the lake of Moiris and
especially in that region which is called the Delta, if that land
continues to grow in height according to this proportion and to
increase similarly in extent, will suffer for all remaining time, from
