1 Now in Arabia, not far from Egypt, there is a gulf extending inland from the sea called Red , whose length and width are such as I shall show:
2 in length, from its inner end out to the wide sea, it is a forty days' voyage for a ship rowed by oars; and in breadth, it is half a day's voyage at the widest. Every day the tides ebb and flow in it.
3 I believe that where Egypt is now, there was once another such gulf; this extended from the northern sea towards Aethiopia, and the other, the Arabian gulf of which I shall speak, extended from the south towards Syria; the ends of these gulfs penetrated into the country near each other, and but a little space of land separated them.
4 Now, if the Nile inclined to direct its current into this Arabian gulf, why should the latter not be silted up by it inside of twenty thousand years? In fact, I expect that it would be silted up inside of ten thousand years. Is it to be doubted, then, that in the ages before my birth a gulf even much greater than this should have been silted up by a river so great and so busy?
