Amphion and Zethus
Amphion and Zethus, another pair of twins fathered by Zeus and Antiope, are portrayed as the legendary founders of Thebes. They are called "Dioskouroi, riders of white horses" (λευκόπωλοι) by Euripides in his play "The Phoenician Women" (the same epithet is used in "Heracles" and in the lost play "Antiope"). In keeping with the theme of distinction between the twins, Amphion was said to be the more contemplative, sensitive one, whereas Zethus was more masculine and tied to physical pursuits, like hunting and cattle-breeding.
