Dan was the tribe of great navigators of Israel, many of whom during the time of The Judges sailed up into the Black Sea (Danube, Dneister, Dneiper rivers), and to Greece known as the Danaoi where they apparently intermarried with Hellenes (progeny of Elisha/Hellen) the Achaeans, confirmed by medieval Irish texts saying that the Tuatha de Danann had come from Achaia.
