Why does Athena have a shield?

Athena, the Greek goddess of wisdom and warfare, is often depicted with a shield known as the Aegis. This shield symbolizes her role as a protector and a strategic warrior, embodying both defensive and offensive capabilities in battle. The Aegis is sometimes shown adorned with the head of the Gorgon Medusa, which adds a protective aspect by instilling fear in her enemies. Additionally, the shield reflects her wisdom and tactical prowess in warfare, distinguishing her from other deities of conflict.
