According to Dionysius of Halicarnassus, Dardanus left Pheneus in Arcadia to colonize a land in the North-East Aegean Sea. When Dardanus' deluge occurred, the land was flooded and the mountain where he and his family survived formed the island of Samothrace. He left Samothrace on an inflated skin to the opposite shores of Asia Minor and settled on Mount Ida. Due to the fear of another flood, they refrained from building a city and lived in the open for fifty years. His grandson Tros eventually moved from the highlands down to a large plain, on a hill that had many rivers flowing down from Ida above. There he built a city, which was named Troy after him. Today, we call the area the Dardanelles (formerly known as Hellespont), a narrow strait in northwestern Turkey that connects the Aegean Sea to the Sea of Marmara. The name is derived from Dardania, an ancient land on the Asian shore of the strait which in turn takes its name from Dardanus, the mythical son of Zeus and Electra.
