 In a famous passage in chapter 4 of the "Poetics", Aristotle formulated the hypothesis that the earliest forms of comedy originated and evolved from "those who lead off the phallic processions", which were still common in many towns at his time.The city of Tyrnavos in Greece holds an annual Phallus festival, a traditional phallophoric event on the first days of Lent.In August 2000, to promote a representation of Aristophanes' "The Clouds", a traditional Greek phallic procession had been organized, with a long phallus paraded by the cast with the accompaniment of Balkan music; the phallic device was banned by the staff of the Edinburgh Festival.
