In Greek mythology, Pentheus was a king of Thebes. His father was Echion, the wisest of the Spartoi. His mother was Agave, the daughter of Cadmus, the founder of Thebes, and grandson of the goddess Harmonia. His sister was Epeiros and his son was Menoeceus.

Dragon's teeth (mythology)
In Greek myth, dragon's teeth feature prominently in the legends of the Phoenician prince Cadmus and in Jason's quest for the Golden Fleece. In each case, the dragons are present and breathe fire. Their teeth, once planted, would grow into fully armed warriors.
