According to Greek Myth Zeus was married 4 times, 1st to Metis, 2nd to Themis, 3rd to Eurynome and finally to Hera.
Metis (on the right) was an Oceanid and a Titan and was the Titan Goddess of Good Council and Wisdom. She was his first wife and the mother of his favorite child Athena. Gaia told of a Prophecy in which their son (she was pregnant with Athena when the prophecy was told) would over throw Zeus so he tricked her into changing into a fly and he swallowed her like his father did to his siblings, she remained inside Zeus for many years until after Athena was full grown and she caused a headache which caused Zeus to get another God to take a axe to his head (since he was immortal he would be alright) and allowed Athena to emerge, she may have also emerged and went off somewhere. It's possible the Prophecy was told by Gaea as she was upset with Zeus for imprisoning several of her children and upset with her for some reason and want to keep them appart and she may have did something to Zeus to cause him to react the same way as his father. She was the daughter of Oceanus and Tethys.
Themis was the Titan Goddess of natural order, divine law and tradition as well as the oracles of the earth. She was the daughter of Ouranus and Gaia, and was formally a wife (his second) of Zeus before they seperated. She counciled Zeus on matters and was by him the mother of the 3 youngest Horai (the Seasons): Eunomia, Dike, and Eirene. As well as Praxidike, The 3 Themeides Nymphs and possibly the 3 Litae (goddess of Prayers who followed Ate as she wondered the earth). They would later divorce for some uknown reason.
Eurynome was an Oceanid Nymph and a Titan Goddess of water-meadows and pasturelands and was the daughter of Oceanus and Tethys and sister to Metis. She became Zeus 3rd wife and by him was mother of the 4 elder charities, Aglaia, Pasithea, Euphrosyne and Thalia. She and Zeus later divorced for unknown reasons.
Hera was the Goddess of Marriage and was 4th and final wife of Zeus as well as his older sister. She was tricked by Zeus into laying with him and he married her and she also became the Queen of the Gods. She was known for being vindictive and jealous, especially on Zeus' lovers even before she was his wife like trying to prevent Leto from giving birth, so she was in love with and jealous of his lovers. She is also known for having tossed her deformed son Hephaestus off of Olympus. She had several children by him. Although interesting to note is that it is unknown if Zeus and Metis actually divorced unlike with his 2nd and 3rd wife so she may not actually be married to Zeus and is the other woman.
