Cylon of Athens

Cylon was an Athenian of the archaic period in Ancient Greece, primarily known for the events of the Cylonian Affair, an attempted seizure of power in the city. Cylon, one of the Athenian nobles and a previous victor of the Olympic Games in 640 BC, attempted a coup in either 636 BC or 632 BC with support from Megara, where his father-in-law, Theagenes, was tyrant.
