After the Tower of Babel, some of the progeny of Heber and his son Peleg moved north to the Caucasus region where became known Iberia, and some of them built the megalithic “pelasgian” structures now submerged (since the end of the Ice Age) in the Black Sea off Anapa, Russia, then some sailed west across the ice age Black Sea basin (it was a huge lake during the Ice Age) to the Hellespont and beyond to ice age Greece where the Pelasgians were known as great navigators and builders, ruins of many of their megalithic buildings submerged off islands of Greece such as Pelagos since circa 1500 b. c. when the Ice Age began to end. The Hebrus river originating in the Rila mountains of western Bulgaria was named for Heber, and west of those mountains in Albania is spoken the Arvanite language, the modern remnant of Pelasgian, the ancient ancestors of those in Albania speaking Arvanite having come across the Rila’s when the Ice Age had ended.
