The Gods

Zeus-

In Greek mythology, the chief of the Olympian gods (Roman Jupiter). He was the son of Kronos, whom he overthrew; his brothers included Pluto and Poseidon, his sisters Demeter, Hestia, and Hera. As the supreme god he dispensed good and evil and was the father and ruler of all humankind, the fount of kingly power and law and order. His emblems were the thunderbolt and aegis (shield), representing the thundercloud. The colossal ivory and gold statue of the seated god, made by Phidias for the temple of Zeus in the Peloponnese, was one of the Seven Wonders of the World.

Zeus ate his pregnant first wife Metis, goddess of wisdom, fearing their child Athena would be greater than himself. However, Athena later sprung fully armed from Zeus' head when Hephaestus split it with an axe. His second wife was Themis, the personification of order, and third Hera, but he also fathered children by other women and goddesses. The offspring, either gods and goddesses or godlike humans, included Apollo, Artemis, Castor and Pollux/Polydeuces, Dionysus, Hebe, Heracles, Hermes, Minos, Perseus, and Persephone.

Hermes-

In Greek mythology, the messenger of the gods; son of Zeus and Maia, one of the Pleiades. Homer's Odyssey presented the god as the conductor of the dead (shades) to Hades, in which capacity he became associated with the underworld and dreams. Identified with the Roman Mercury and ancient Egyptian Thoth, he protected thieves, travellers, and merchants. As a god of good fortune, he presided over some forms of popular divination, public competitions, and games of dice.

Medusa -

In Greek mythology, a mortal woman who was transformed into a snake-haired Gorgon by Athena for defiling the goddess's temple with the god Poseidon. She was slain by the hero Perseus who watched her reflection in his shield, as her head was so hideous – even in death – that a direct beholder was turned to stone.

The winged horse Pegasus and warrior Chrysaor were said to have sprung from her blood; offspring of Medusa and Poseidon.
