Semele is the goddess of madness, and is the mother of Dionysus. She was a Theban princess loved by the god Zeus. Hera later on found out about their secret relationship, and made Zeus accidentally hit her with his lightning bolts, when she was pregnant with Dionysus. He later on recovered and reached adulthood in Mount Olympus, and soon requested her to join the company of the gods.
Semele is now quiet, ever since the lightning bolt affected her.
People call her either Semele or Thyone.
Semele's officila Greek name is Θυωνη or Σεμελη.
