The Atlas Mountains stretch for over 1,500 miles across the Maghreb of North-West Africa, from Morocco through Algeria to Tunisia. The origin of the name is unclear but seems to be generally accepted as having been named after the Titan.
Herodotus states (The Histories, Book IV. 42-43) that the inhabitants of ancient Mauretania (modern Morocco) were known as Atlantes and took their name from the nearby mount Atlas. Jean Gattefosse believed that the Atlas Mountains were also known as the Meros and that a large inland sea bounded by the range had been known as both the Meropic and the Atlantic Sea. Furthermore, he contended that Nysa had been a seaport on this inland sea.
*The Maghreb, or parts of it, have been identified as the location of Atlantis by a number of commentators. One, Ulrich Hofmann concluded his presentation to the 2005 Atlantis Conference with the comment that “based on Plato’s detailed description it can be concluded that Atlantis was most likely identical with the Maghreb.”[629.377] Furthermore, he has proposed that the Algerian Chott-el-Hodna has a ring structure deserving investigation.*
