Under the Athenian tyrant Peisistratus, the Greater Panathenaia festival was reorganized around 566 BCE to include competitive recitations of the Iliad and Odyssey by professional rhapsodes. Performers recited in relay sequence, each picking up where the previous rhapsode stopped, ensuring complete sequential performance of both epics. Ancient sources credit Peisistratus's son Hipparchus with formalizing this rule. The competitions attracted rhapsodes from across the Greek world to Athens, standardizing the Homeric texts and establishing Athens as the center of their cultural transmission.
