It is not precisely known who were the first residents of Kassos. Anyway, there are indications that Achaeans had lived on the island before the Phoenicians. These indications are strengthened by certain findings in the Ellinokamara cave and by the fact that a place in about the centre of the island is named Argos. After Achaeans and Phoenicians the Dorians came by and eventually the island generally had the same luck as Dodecanese and especially its neighbor Karpathos.
