Stephanos of Byzantium - Ethnika
Kaunos: a city in Karia, named after Kaunos; his sister Byblis fell in love with him and, when he fled, [hanged herself]. Hence the proverb, 'the Kaunian love'. It is unhealthy, and for this reason Stratonikos the kithara-player too, seeing that the Kaunians were notably pale, said, 'Just as is the generation of leaves, so too that of men.' There is also another city in Crete. The ethnonym is 'Kaunios', and 'Kaunia' and 'Kaunaios'.
