Athena
Athena is the Greek goddess of wisdom, warfare, handiwork, and strategy. She is one of the Twelve Olympians. Athena's symbol is the owl, the wisest of the birds. She also had a shield called Aegis, which was a gift given to her by Zeus. She is usually shown wearing her helmet and often with her shield. The shield later had Medusa's head on it; after Perseus killed her, he gave the head of Medusa to Athena for safekeeping and she put the head on her shield.
