How each was worshipped

Hera

Cult sites: Heraion of Argos; Heraion of Samos; Temple of Hera at Olympia
Festivals: Heraia; Daedala (Boeotia)

Argos and Samos kept her oldest houses. The Heraia were women's games at Argos and a foot-race at Olympia. Marriage, cattle, and the cuckoo or peacock are hers; the cult is civic and jealous, not only a wedding story.

Poseidon

Cult sites: Sanctuary of Poseidon at Isthmia; Temple of Poseidon at Sounion; Onchestos in Boeotia
Festivals: Isthmian Games; Posideia

Horses, earthquakes, and the drowned coast are his working signs. Isthmia held games under his name. A bull often went to the sea. Inland Boeotia kept him as a horse god, not only a sailor's patron.

The two figures

Greek Pantheon

Hera

Queen of the gods and goddess of marriage and family. Wife and sister of Zeus, known for her jealousy toward Zeus's lovers and illegitimate children.

Hera was the eldest daughter of Cronus and Rhea, swallowed by Cronus at birth and later freed by Zeus. She became Zeus's wife after he courted her in the form of a cuckoo bird.

Hera is the majestic queen of Olympus and the goddess of marriage and childbirth. As the wife of Zeus, she holds immense power, but she is most famously known for her jealousy and vengeance against Zeus's lovers and illegitimate children.

Greek Pantheon

Poseidon

God of the sea, earthquakes, and horses. Brother of Zeus and Hades, ruler of the oceans and all waters.

Poseidon rules the vast oceans, earthquakes ("Earth-Shaker"), and horses. He is a moody and tempestuous god, much like the sea itself. Sailors prayed to him for safe passage, often sacrificing horses or bulls to appease his wrath.

About this comparison

Comparisons pair figures that play a similar role across traditions, or that the myths connect within one. A shared role does not, by itself, establish a shared origin.
