Metis (Μῆτις) is the Greek word for **"cunning wisdom, skill, craft."** **The Greek Titaness of wise counsel, planning, cunning, and craftiness** — Zeus's first wife. **An oracle prophesied that any son she bore would be greater than his father, so Zeus swallowed her whole while she was pregnant** — Athena was later born fully grown and armored from Zeus's forehead, after Hephaestus split it open with an axe. **Metis remains inside Zeus, serving as his counsel** — Hesiod tells us that this is the source of Zeus's wisdom.
Featured throughout Hesiod's *Theogony* and Apollodorus's *Library*.
Metis reduces to nine — the number of cunning wisdom.
