In Homer’s epic the Odyssey, Helen of Troy fled (circa 1200 B.C.) to Pharos Island, off the coast of present-day Alexandria, Egypt, with no mention of the ancient riverport cities (of the now extinct Canopic branch of the Nile), about 10 miles to the east of Pharos, on the other side of Cape Zephyrion, submerged in Aboukir Bay, three miles from shore, the submerged ruins of ancient Herakleion/Thonis and Menouthis, on the submerged river channel of the Canopic branch of the Nile, which was but a trickle by the time Alexander the Great arrived circa 350 B.C. to found Alexandria, on the coast facing Pharos Island, where the trojan Helen sought refuge for a time some 900 years previously (when Menouthis and Heraklion were nowhere in sight lest she would have gone there).
When Menouthis and Herakleion were thriving port cities at the mouth of the Canopic branch, when sea level was much lower, Pharos Island was but a hill near the coast at that time, to later become an island when sea level rose, when also, Herakleion and Menouthis were consumed by the sea, but nautical archaeologist Franck Goddio, who has photographed the extensive submerged ruins of paved streets, temples, port factilities, and statues, says the cities sloughed off into the sea about 2,000 years ago, not by sea level rise, but by erosion and earthquakes, however, ruins 3 miles from shore cannot be explained by erosion nor earthquakes, it would have had to have been like a roller coaster ride out to sea.
And Alexander, when he arrived in the area, built a port city there, because obviously, there were no others around, with no mention of Herakleion nor Menouthis in his chronicle, so those cities were submerged before Alexander’s time, and even before the time of Homer’s Odyssey, which happened about 900 years before Alexander’s time, putting the submergence in the time of the greek Flood of Ogyges, when much of Greece was consumed by the sea, actually when the Ice Age ended, with Ogyges acknowledged to have lived circa 1500 b.c.
And when you realize that Plato’s bronze age Atlantis, in the Gibralter region (with trireme ships, metallurgy, and global navigation), went under not about 11,600 years ago, but 3,500 years ago, it’s obvious that was when the egyptian port cities went under too, as well as, much of Greece (as told in the story of the Flood of Ogyges and also in Plato’s story about Atlantis), corroborated by submerged megalithic ruins off Greece, Spain, Morocco, Egypt, Israel/Lebanon, and many other locations around the world, proving that the Ice Age ended much later than popularly advertised, in perfect line with the biblical timeline, with the ancient navigational capabilities of those ancients explained in article #2 at http://IceAgeCivilizations.com, the method by which the dimensions for the Great Pyramid, and thereby, the length for the royal cubit, were established, according to intelligent design of the universe by the God.
