From the Perry-Castañeda Library Historical Atlas by William R. Shepherd.
Flowing for 5584 km (3470 miles), the Nile River is the longest river in the world. The delta of the Nile River empties into the Mediterranean Sea. The beginning of the Nile is south of Egypt in Lake Victoria.
On this map you can see the city named for Alexander the Great at the top -- in the Mediterranean. Also note the Old Kingdom capital city of Memphis, with Giza (spelled Gizeh) to its west. In Plato's Timaeus Solon hears the story of Atlantis while visiting the Egyptian city in the Nile Delta that is marked on the map as Sais.
