Assaf Yasur-Landau argues that the Philistines reached Canaan by this route, which led from Greece through the Dardanelles (the only major body of water on the journey) to Anatolia, and then southward to the Levant. The land routes, writes Yasur-Landau, would have been passable at the end of the Late Bronze Age, when political upheaval weakened the kingdoms along the way, many of which would have ordinarily presented obstacles to any party of migrants.
