Greeks already had Athena, so they didn't need another god of wisdom.
Tsk, tsk, Jimthedog, you have been neglecting your Bulfinch's Mythology lately.

also spelled Athene, in Greek religion, the city protectress, goddess of war, handicraft, and practical reason, identified by the Romans with Minerva (q.v.). She was essentially urban and civilized, the antithesis in many respects of Artemis, goddess of the outdoors. Athena was probably a pre-Hellenic goddess and was later taken over by the Greeks. Yet the Greek economy, unlike that of the Minoans, was largely military, so that Athena, while retaining her earlier domestic functions, became a goddess of war.
