Metis
Μῆτις
The goddess of cunning — Zeus's first wife, whom he swallowed whole.
It was Metis who gave Zeus the drug that made Cronus vomit up his children.
When a prophecy warned that the son she bore would surpass him, Zeus swallowed her, pregnant, whole.
That is why Athena is born from Zeus's head. The Greek word mētis also means craft and cunning.
