According to the ancient historian Hesiod, Metis was the wife of Zeus, he swallowed her when she was pregnant knowing that Metis was to bare Athena and then another child who would become the ruler of the Universe. It was Zeus however, who bore Athena not Metis.

Hera was the wife of Zeus, but Zeus had a child with Metis. Here is how the story goes: ( In the story is Jupiter is Zeus, and Minerva is Athena, the Roman names of the gods.) Jupiter, king of gods, was Athena’s father, and her mother was Metis, a minor goddess in Roman mythology. Metis obviously became pregnant. Now, it was prophesised by a fortune-teller that if Metis had a son, he would kill and overthrow his father. In Roman mythology, powerful gods loved their sons, but their biggest, most major gear was to be killed and overthrown by their own son. For Jupiter, it was even worse, it was even more frightening for him- as there was a sort of history of this. For Jupiter had killed and overthrown his father, and his father had done the exact same thing to his father! Jupiter went to desperate measures to overcome this common fate. This is what he did. He swallowed Metis. Soon after consuming Metis, he began experiencing a headache so bad he started thrashing his head against a rock. His son Hephaestus,. A blacksmith, hit Jupiter on the forehead with a mallet in a bid to relieve his father of his pain. Jupiter’s forehead split open and out from his cracked skull sprang a tall, fully-grown, grey-eyed maiden and that was Minerva! As she sprang from her father’s cranium, she instantly became goddess of intellect and wisdom. She was fully-grown and dressed in a helmet, breastplate: full armour; and was holding a lance and a spear, when born. She never took this off. Another story is: Athena’s mother was Metis, a daughter of the almighty Titans that ruled the earth before the Olympians overthrew them. Athena’s father was Zeus, king of the gods. Metis was expecting a child. Zeus went to see an oracle, a fortune-teller. The oracle said this to Zeus: “Metis will bear a son. And this son of yours will overthrow you, just as you overthrew your father Cronus, and just how your grandfather, Uranus, was overthrow by your father.” Zeus was frightened as all Greek gods were of losing their power to their sons, although there was no doubt that Zeus would love his son all the same. As you could see, there was a history of this taking the throne in this manner, and Zeus decided to be extremely precautious. He swallowed Metis. That’s right, he gulped her down. Soon after, he began experiencing an incredible headache. It was so bad he started thrashing his head against a rock. Hephaestus, Zeus’s son by Hera, ran to the rescue. With his huge blacksmith mallet, Hephaestus hit Zeus on the forehead in a bid to relieve his father of his pain. Zeus’s skull split open and out sprang a tall, fully-grown maiden with grey-eyes. She was dressed in the most flabbergasting attire: she was wearing full armour including a breastplate, a shield and a helmet and she was grasping a spear in one hand and a lance in the other. She was Athena. As she was born from her father’s head, she became goddess of intellect, the mind and especially wisdom. And as she was fully-grown and was wearing full armour when she was born in the most astonishing way possible, she became goddess of war and battle. Combing both abilities, in battle she was considered the goddess of the intellectual and tactual side of war.

If you look in any Mythology story...the first comment was correct from what I can see. Were reading on Mythology in my school, so I know that this story is correct. And Athena was born out of her fathers head becasue he swallowed Metis. But Metis wasnt a goddess so of course she died in his stomach. But Athena was a goddess so she lived of course.
