Pentheus (Πενθεύς) (Pentheús) was a king of Thebes in Greek myths and legends. Echion (Ἐχῑ́ων) was his father and Agave (Ἀγαύη) (Agaúē) was his mother. Epirus (Ἤπειρος) (Ḗpeiros) was Pentheus' sister. Also, the character had a son named Menoeceus (Μενοικεύς) (Menoikeús).
He was killed by his mother Agave and her sisters. It was tragedy.
The creature Sphinx (Σφίγξ) guarded Thebes (Θῆβαι), the Greek city. Typhon (Τυφῶν) and Chimera (Χίμαιρα) were her parents. Hera (Ἥρα) or Ares (Ἄρης) sent her in this place. The Sphinx had her own riddle. It sounds like this:
"Which creature has one voice and yet becomes four-footed and two-footed and three-footed?"
She killed who couldn't answer this question.
Oedipus (Οἰδίπους) solved the riddle of Sphinx.
"Person-who crawls on all fours as a baby, then walks on two feet as an adult, and then uses a walking stick during old age," he answered.
Afterwards, the creature killed herself.
Later Oedipus became the king of Thebes.
This riddle is popular in culture and art.
