Gylon

Gylon , also known as Gylon of Cerameis, Gylon is said to have betrayed Nymphaeum to "the enemy" when in 405 BC, he handed it to the Bosporan King Satyros in exchange for needed grain. One theory is that it was no longer feasible for the Athenians to maintain the outpost. but Glyon was punished for his role in letting go of Nyphaeum. He was first sentenced to death, but the punishment was later changed to a fine that Demosthenes paid off. They had a daughter, Cleobule , who married Demosthenes Senior and they had a son Demosthenes.
