Sacred Haven of Debauchery

Zeus's wives were:

Metis (swallowed by Zeus)
Themis
Hera (Zeus's last "official" wife). According to Callimachus, when Cronus ruled the world, Zeus and Hera hid their marriage for 300 years[22].
Zeus had many lovers:

Eurynome
Demeter
Mnemosyne
Leto (Latona)
Io
Europa
Leda
and many others (see the section Children of Zeus)

Calliroe is also mentioned as Zeus's lover, the mother of Amphoter and Acaranus, as well as Thiva and Phthia.

Some myths claim that Zeus wanted to leave Hera for Thetis, but he didn't do so because of a prophecy – the Nereid would give birth to a son who would surpass his father in everything. Thetis married King Peleus, and they had Achilles.

Synope and Medea rejected Zeus.

The young man Aitos (see Myths of Crete) and Ganymede are also called his lovers.

In the form of a snake, he seduced Demeter, and then Persephone; in the form of a bull and a bird – Europa; in the form of a bull – Io; in the form of an eagle – Ganymede; in the form of a swan – Nemesis (who became a goose) or Leda; in the form of a quail – Leto; in the form of an ant – Eurymedusa; in the form of a dove – Phthia; in a fiery form – Aegina; in the form of a golden shower – Danaë; in the form of a satyr – Antiope; in the form of a shepherd – Mnemosyne; in the form of a stallion – Dia. His lovers usually retain human form, but he turns Callisto into a bear and Io into a cow.
