This chapter discusses both premieres and post-premiere performances in Classical Athens and Attica by focusing on their venues and on the tragedies involved. The main dramatic festivals in Athens, the Great Dionysia and the Lenaea, offered post-premiere performances only rarely, but the Dionysia held in the demes, the Attic Dionysia, had a more flexible schedule allowing for both types of dramatic events. After discussing the ancient evidence for dramatic contests at the Attic Dionysia, I argue that these festivals had a key role in the early formation of the dramatic canon. As for the tragedies involved, I present three case-studies: Libation Bearers and Edonians by Aeschylus and Euripides’ Telephus. Dramatic texts suggest that these tragedies were mounted time and again already in Classical Attica, and these early performances laid the groundwork for the popularity that these tragedies enjoyed with later actors and audiences.
