Athens, one of the worldâs oldest cities, has a history of over 3000 years. Details of its founding, though, are not known; the rich mythology of ancient Greeks, though, fills in the blanks. According to the legend, Cecrops was the founder and first King of Athens.
Greek tragedy as we know it was created in Athens around the time of 532 BC, when Thespis was the earliest recorded actor. Being a winner of the first theatrical contest held at Athens, he was the exarchon, or leader, of the dithyrambs performed in and around Attica, especially at the rural Dionysia.
