Zeus's father was the king bee of the Titans, he was a not too bright man called Cronus. One of Cronus' great fears was a prophecy that assured him he was going to be killed by one of his sons. Many will argue that this happened a lot in the bad old days when our Limbic Emissions had a less effective Department of Administrative Satisfaction. The point is, every time Cronus' wife Rhea, who was Cronus' sister, bore him a son he swallowed the boy.
This left a problem of succession, which Rhea decided to solve by persuading her husband to swallow a stone instead of swallowing her most recent son, Zeus. And lo, when Zeus came of age he forced Cronus to regurgitate the sons he had swallowed, took advantage of his brothers, none of whom had any love for Cronus, and he made war on the Titans, took control of Olympus, became King of the Gods and in the family tradition he married one of his own many sisters, this one was called Hera, who's pictured above.
In due course Hera had a more serious than usual disagreement with Zeus, this one was about which of her children got what. There was no trying to be reasonable, so in her role as Queen of Olympus she decided that as punishment for Zeus' constant infidelities, in the traditional manner through deception, she'd see to it that her favorite, not his favorite, would get the keys to the Oldsmobile.
Say what you like about the close relationship the Greek Gods had with their Limbic Emissions and their poorly developed Department of Administration, but if Hera hadn't acted as she did we might never have met the personification of delusion, recklessness, folly and ruin the Ancient Greeks called Atè. She may have been one of Zeus daughters or possibly the daughter of the Goddess of Strife and Discord, but she had keen insights into the Human Condition.
Hera had asked Atè to help her make sure her disputed son Hephaestus received the due respect he deserved and it didn't all go to her undisputed son Aries, who nobody, not even Zeus liked. Relatively speaking, both Hephaestus and Aries were perfectly decent Gods, but the title disputed attached to more gossipy mentions of the name Hephaestus pissed Zeus off because no one in Olympus believed, even for God's, that parthenogenesis, which is another name for Virgin birth, was a real thing. If it wasn't Zeus then someone else had sired Hephaestus, and there was every reason to believe Hera was as well attached to her own Department of Limbic Emissions as any other traditional Queen of the Gods.
Well it wouldn't be Ancient Greece if Atè had managed to successfully deceive Zeus. Hera claimed innocence, apart from which she was a Queen and the Goddess for women, marriage, childbirth and family, and of course she was perfect. Zeus was furious, he had to do something, he grabbed Atè by her hair and threw her down to earth where she kept herself occupied by blinding the minds of both gods and men, causing them to do dreadful and foolish things.
The Greeks believed in a kind of blindness and delusion they identified as Atè. It just came over you, it wasn't really your fault, but once the wrong was done, it still created a Blood-Debt. If someone stole your wife and took her to live a life of luxury in Troy as opposed to the rather tedious and isolated lifestyle offered to the most beautiful female mortal in the world by a Greek Property Owner who spent most of his time out with the lads beating up on neighboring City States, you were duty bound to get her back or die trying. This eye for an eye logic was well sourced in Limbic Emissions and is still very much a subject of dispute in those interstitial spaces between "I" and "Me."
Nonetheless, Atè, somewhere in her devious soul, had given Hannah Arendt the beginning of her understanding of forgiveness. An opportunity for a New Beginning as opposed to some soppy excuse for not putting any effort into getting your own revenge right here on earth.
