"Zeus, as king of the gods, took as his first wife
Metis: A Sea Nymph
While pregnant, Metis warned Zeus that their son would eventually overthrow him. Zeus was so horrified by this prospect that he tricked Metis into turning herself into a fly, and swallowed her whole.
In some versions of Greek mythology, Zeus ate his wife Metis because it was known that their second child would be more powerful than him. After Metis's demise, their first child Athena was born when Hephaestus cleaved Zeus's head open and the goddess of war emerged, fully grown and armed.
Metis, the goddess of wisdom, was Zeus' first wife. According to a prophecy, she would bear two children. The first would be Athena and the second, a son who would be powerful enough to overthrow Zeus. This made him very anxious.
Seven wives
According to Hesiod, Zeus takes Metis, one of the Oceanid daughters of Oceanus and Tethys, as his first wife.
Zeus finally became enamored of the goddess who was to become his permanent wife — Hera.
Before his marriage to Hera, Zeus consorted with a number of the female Titanes (and his sister Demeter). These liaisons are ordered by Hesiod as follows: (1) Metis; (2) Themis; (3) Eurynome; (4) Demeter; (5) Mnemosyne; (6) Leto.
Greek goddess of marriage, very jealous wife of Zeus, queen of gods.
After Rhea refused to marry him, Zeus turned into a snake and raped her. She had Persephone with Zeus.
Zeus was known in his time as much more than the father of the gods. He was also a womanizer, and as such, he fathered many, many offspring! He would transform into various animals to fulfill his desires; therefore, his 'children' are quite interesting.
As punishment for her attempt to overthrow him, Zeus seized Hera and hung her in the sky by golden chains. Hera wailed in pain all night, but no one would help her out of fear of Zeus.
Cuckoo for Love
So he appeared to her in the guise of a bedraggled, rain-soaked cuckoo. Hera saw the poor bird and kindly brought him into the shelter of her bosom to warm and dry him. Zeus immediately returned to his true form and—true to form, indeed—ravished her.
Amalthaea, in Greek (originally Cretan) mythology, the foster mother of Zeus, king of the gods. She is sometimes represented as the goat that suckled the infant god in a cave in Crete, sometimes as a nymph who fed him the milk of a goat.
In order to forestall these consequences, Zeus tricked Metis into turning herself into a fly and promptly swallowed her. However, she was already pregnant with their first and only child, Athena.
Her father Zeus (Jupiter) had swallowed his pregnant consort Metis (“wisdom”), because he was afraid she would bear a son who would overthrow him.
ZAGREUS A divine son of Zeus and his own daughter Persephone.
Ganymede, a beautiful Trojan young man, was aducted by Zeus to serve as his personal cupbearer and lover on mount Olympus among the other gods.
Antiope in Greek mythology was the daughter of King Asopus of Boeotia. Zeus, enchanted by her beauty, transformed himself into a satyr and raped her. Antiope's rape by the father of the ancient Greek gods was only the beginning of her misfortunes. Soon after it became evident that she was pregnant with Zeus' child.
Who hasn't Zeus slept with? According to a Homeric Hymn, there are three goddesses whom Aphrodite “can't persuade or decieve”, i.e. who don't feel sexual desire and are perpetually virgins. They are Athena, Artemis and Hestia. So, we are sure that Zeus did never have affairs with any of those three.
A while later, he rapes her, she agrees to marry him and they create a family on Mount Olympus, the Deities' new home. Unfortunately, Zeus constantly cheats on Hera and he has done it over a hundred times, but in the end Hera always forgives him.
Zeus slept around because he thought it was fun. Zeus wanted to have as much offspring as possible.
Revenge on Zeus
Hera was a very jealous and vengeful wife. She wanted Zeus all to herself, but Zeus cheated on her constantly with other goddesses and with mortal women. Hera often took out her revenge on the women who Zeus loved and the children they had with Zeus.
Zeus had an eye for ladies from all walks of life, and his affairs with mortals often resulted in mortal children. Some estimates have come up with around 51 children of Zeus who were not divine in nature. Even though they were mere mortals, many of them went on to make history in other ways.
Accordingly, the Greek god Zeus's affairs were with willing participants – regardless of his trickery and disguise to seduce them. The male-dominated art world interpreted Zeus's promiscuity as part of fulfilling his duty to populate the newly formed world.
Some estimates put the count at well over a hundred, with the lovers being mostly but not exclusively female. In some cases, ancient authorities differ, so the exact lineage and relationships remain open to debate.
