Imagine just getting on a ship and heading out to sea kind of aiming for another city. That’s crazy when you think about it but we did it like it was nothing.

There's a thick, info filled book called "The Mediterranean" by Braundel. One of the things I got from there was the spacing of what are now cities along the north coast of the med is the distance a ship could sail in one day.

I haven't read both of them, just parts. The kind of books that I'd pick up and read bits and pieces. (And finding cheap copies was easier a couple of decades ago.)

But really interesting in how that pond became so important.

Speaking of maps: LINK The Tabla Peutingeriana is a map of the Mediterranean, but not the way we expect maps to be.

Nice.

Re: That under Sahara river

Libya has found a lake big as lake michigan under ground in south central Libya.

Change the title.

Black sea

Title changed. (I didn't know it was this easy. Thankee.)

The river/lake under the Sahara is an aquifer full of Pleistocene aged water, left over from the time of glaciers.

About 40+ years ago, the AAPG sent around a speaker who had worked in Libya and he talked about that water and the government's decisions to pump it up for agriculture. The alternative was for it to flow to the surface and evaporate in a band of saline swamps. That was multiple generations of despots ago, but it was a memorable talk.
