Dionysus or Dionysos (in Greek, Διόνυσος or Διώνυσος; associate with Roman Liber), is the god of wine, the inspirer of madness, and a major figure of Greek mythology. He represents not only the intoxicating power of wine, but also its social and beneficial influences. The geographical origins of his cult were unknown, but almost all myths depicted him as having "foreign" (i.e. non-Greek) origins.
