In 335-334 BC, Lysicrates, sponsor (choregos) of a play performed at the Big Dionysia theatrical contest, built the monument to celebrate his victory. That's why it's called a choragic monument. They put a bronze tripod on it. The same was done with all the choragic monuments that were arranged on the same street, starting from the theatre of Dionysus. For this reason, the street’s name was Tripodon (Tripods) Street, as it is today. For obvious reasons, the frieze of the monument depicts a mythological scene with Dionysus. Tyrrhenian pirates have captured him without knowing who he is. He punishes them by transforming them into dolphins.
