Noted greek historians Herodotus and Apollonius of Rhodes (author of Jason and the Argonauts) wrote about Lake Tritonis in Libya (North Africa), according the the geographic hints given where today is the Great Eastern Erg in Algeria, just south of Tunisia, which began to go dry just over a thousand years before those greek writers lived, hence their familiarity with it, as well fem Plato that Greece (Pelasgia) once flowed with streams for bountiful crops where by classical greek days were dry beds.
