Mareotis

Mareotis, Lake, now called El Mariut, a brackish lake in northern Egypt, separated from the Mediterranean by a narrow strip of land, on which part of Alexandria is situated. It is 40 miles long and 18 broad. It was once navigable, but has frequently so far dried up as to be no more than a marsh, as in 1882.
