In Greek mythology, the god associated with wine and revelry is Dionysus. Known as Bacchus in Roman mythology, Dionysus embodies the spirit of fertility, ecstasy, and liberation. He presides over wine, festivity, and the theater, representing the dual nature of intoxication as both joy and chaos. His followers, including the Maenads and satyrs, celebrate the loosening of social constraints, underscoring themes of transformation and the connection between nature and divine inspiration.
