Metis

By the era of Greek philosophy in the fifth century BCE, Metis had become the Titaness of wisdom and deep thought, but her name originally connoted "magical cunning" and was as easily equated with the trickster powers of Prometheus as with the "royal metis" of Zeus.[1] The Stoicc (Stoicism) commentators allegorized Metis as the embodiment of "prudence", "wisdom" or "wise counsel", in which form he was inherited by the Renaissance.[2] The Greek word metis meant a quality that combined wisdom and cunning. This quality was considered to be highly admirable and was regarded by Athenians as one of the notable characteristics of the Athenian character. Metis was the one who gave Zeus a potion to cause Kronos to vomit out Zeus' siblings.[3] http://en.wikipedia.org/wiki/Metis_(mythology)
