The legendary city of Alexandria was founded by Alexander the Great as he swept through Egypt in his quest to conquer the known world.
Now scientists have discovered hidden underwater traces of a city that existed at Alexandria at least seven centuries before Alexander the Great arrived, findings hinted at in Homer's Odyssey and that could shed light on the ancient world.
Alexandria was founded in Egypt on the shores of the Mediterranean in 332 B.C. to immortalize Alexander the Great. The city was renowned for its library, once the largest in the world, as well as its lighthouse at the island of Pharos, one of the Seven Wonders of the Ancient World.
They used coring to find it.
