The Dioscuri (Castor and Polydeuces) vs Hunahpu and Xbalanque

The divine twins Castor, tamer of horses, and Polydeuces (Pollux), the boxer, sons of Leda and brothers of Helen. Sailors prayed to them in storms, and after Castor's death the brothers were said to share immortality, alternating days between Olympus and the world below.

Leda bore the twins beneath Mount Taygetus after Zeus lay with her; some versions make only Polydeuces the son of Zeus and Castor the son of her husband Tyndareus. Their sisters were Helen and Clytemnestra.

The Homeric Hymns call the Tyndaridae the sons of Zeus, born to Leda beneath Mount Taygetus in Sparta: Castor the horse-tamer and Polydeuces the boxer. Other traditions differ: the *Odyssey* calls both sons of Leda's husband Tyndareus, while Pindar divides them, making Castor mortal and Polydeuces the immortal son of Zeus.

The Hero Twins of Maya mythology, sons of the maize god Hun Hunahpu. Through cleverness and sacrifice, they defeated the lords of death and became the sun and moon.

The Hero Twins were miraculously conceived from their father's skull. Born in the upper world, they became great heroes who defeated false gods, outwitted the lords of death, and became the sun and moon.

Hunahpu and Xbalanque are the central heroes of the **Popol Vuh**. Their adventures feature monster-slaying, underworld journeys, death and resurrection, and the establishment of cosmic order.
