Many Greek heroes are responsible for founding a city or being the ancestral head of some powerful dynasty of later heroes. This episode (32) focuses on Cadmus, who arrives in Greece while searching for his missing sister. He goes on to found the city of Thebes after killing a serpent dragon and marries Harmonia, an immortal daughter of the gods Ares and Aphrodite. I also discuss how their children went through a series of tragedies, most of which were due to offending the gods.
