Dionysus/Bacchus

Dionysus (Greek) or Bacchus (Roman) is the god of wine and fertility.  Born out of the thigh of Zeus/Jupiter, he was raised by nymphs, satyrs, and Silenus.  He saved Ariadne after she was abandoned by Thesus, and married her.  

He is often portrayed with maenads and satyrs, and sometimes Silenus or Ariadne, in a drunken celebration (called the "triumph of Bacchus").  The god himself is sometimes depicted as drunk and frequently holds a thyrsus (wand of fennel).  He can also appear in a chariot pulled by leopards, tigers, or goats.
