"Of these children Dardanus, who was a man who entertained great designs and was the first to make his way across to Asia in a makeshift boat, founded at the outset a city called Dardanus, organized the kingdom which lay about the city which was called Troy at a later time, and called the peoples Dardanians after himself". Diodorus Siculus - Library of History 5.48
