Metis
Zeus turns a succession prophecy into a battle of pride and words.
Zeus, the great presiding deity of the cosmos, took for his first wife Metis, the Titan-goddess of wisdom—“wisest among gods and mortal men.”
We’ve met Metis before—she is the Oceanid and shape-shifter who advised Zeus against his father, Kronos. It was her stratagem that compelled Kronos to disgorge the children he had swallowed.
Hesiod
It was fated that Metis's first child would be the gray-eyed maiden, Tritogeneia Athena, and afterward a son whose overmastering heart would have ruled gods and men alike.
When Metis was about to give birth to gray-eyed Athena, Zeus deceived her with slippery words…
Zeus (jupiter)
My dear Metis, your ability to take any shape is marvelous. To transform yourself into something mighty is no challenge for you.
Your challenge is just the opposite. I imagine it would be beyond your ability to turn into anything insignificant and small. What irony! You can become a great she-bear yet not a trifling honeybee.
Metis
Beyond my ability?? Absurd!
At that, Metis turned herself into a honeybee. Zeus smiled, caught her in his hand, and swallowed her.
Hesiod
This he did at the counsel of Gaia and starry Ouranos, so that no immortal besides himself should ever hold kingly power.
It is rare that anyone—mortal or immortal—can escape the fates. But here, Zeus evaded the prophecy of his downfall and brought an end to the cycle of sons overthrowing their fathers.
By swallowing Metis, he also incorporated her wisdom (literally) into his being. As an immortal she could not die, but remained in his belly forever, adding to his cunning and giving him the power to shape-shift.
Hesiod
Concealed beneath Zeus’s vital organs, Metis conceived Athena, and within his belly fashioned for her daughter the gleaming arms and armor in which she would soon be born.
As the time of birth drew near, Zeus felt a terrible headache. It grew worse and worse, until he called in agony for Prometheus.
Prometheus struck Zeus, split his head, and from his crown Athena sprang, in glorious armor, goddess of wisdom, ‘terror to all armies.’
