Kaunos certainly started with an interesting story. It was founded by Kaunos, who was the son of King Miletos and Kyane, who had tried to prevent Hades from abducting her playmate, Persephone.
Kaunos happened to have a twin sister named Byblis, who started lusting after her brother. When Kaunos learned of her love, he skipped town and ran away with his followers. He named the place where he ran, Kaunos – and so the city was founded.
Byblis, for her part, cried so much that the river Kablys came from her tears. The sources differ on what eventually happened to her, but she either committed suicide or died of grief.
The city of Kaunos, on the other hand, grew to be an important city due to its two ports.
During the Hellenistic times after Alexander the Great, Kaunos was ruled by the Seleukids, Ptolemies, and Antigonids.
