Aristotle Describes Efforts to Connect the Nile to the Red Sea

350 BCERed Sea

"One of their kings tried to make a canal to [the Red Sea], for it would have been of no little advantage to them for the whole region to have become navigable; Sesostris is said to have been the first of the ancient kings to try, but he found that the sea was higher than the land. So he first, and Darius afterwards, stopped making the canal, lest the sea should mix with the river water and spoil it."
