What is the name of Athena's protective shield?

The story behind the answer

Aegis is correct because it is the famed protective shield (or breastplate) associated with Athena, often depicted edged with snakes and bearing the Gorgoneion—the head of Medusa—which struck terror into enemies. In myth, the Aegis is sometimes said to belong to Zeus and be lent to Athena; its name likely comes from “aigis,” meaning goatskin, perhaps referencing the goat Amalthea. Beyond physical defense, it symbolizes divine authority and protection.

Memory tip: “Under the aegis of” still means “under protection” today. Picture Athena’s Aegis flashing the Gorgon’s face—instantly petrifying foes—and remember A for Athena and Aegis as a pair of “A’s” of protection.
