Kalymnos Island

God used a sieve to create Kos and Kalymnos island.
Looking towards East, he used the good and rich earth, to create KOS island. 
He threw to his backside, the rocks and the bit of earth remained in the sieve to create KALYMNOS island.

This myth accurately describes the morphology of Kalymnos island. A lot of rocky mountains with a bit of cultivated earth. This is the reason that Kalymnians work a lot with the sea and became great rock builders, sailors and worldwide famous divers.
