The name Bacchus originates from the Greek Βάκχος (Bakchos), derived from ἰάχω (iacho) meaning 'to shout'. It is another name for the Greek god Dionysus, commonly used by the Romans. Dionysus is the god of wine-making, orchards, fruit, vegetation, fertility, festivity, insanity, ritual madness, religious ecstasy, and theatre. The name Bacchus is associated with the frenzy (baccheia) he induces, symbolizing liberation through wine, music, and ecstatic dance.
