Hydria with scene from a story of Dionysus (Bacchus). While travelling to Greece by sea, pirates overtook Dionysus’ ship. They repeatedly tied him up but the ropes wouldn’t fasten. Dionysus then began to cover the ship with vines. In their desperation to escape the pirates leaped into the sea, turning into dolphins as they did so.
On this hydria, Dionysus is represented by the vines on the left of the scene.
