From Euripides' The Bacchae...

Dionysus: "It's a wise man's part to practise a smooth-tempered self-control."

Dionysus: "Your [Pentheus'] name points to calamity. It fits you well." (The name "Pentheus" derives from πένθος, pénthos, grief)

Messenger: "Dionysus' powers are manifold; he gave to men the vine to cure their sorrows."

Dionysus: "Can you, a mortal, measure your strength against a god?"
